// GENERAL5 QUESTIONS
Response times, call-out fees, licensing and the guarantee — the basics, up front.
Most Sydney jobs booked before early afternoon are done the same day, and genuine 24/7 emergency callouts typically land within the hour. We confirm a tight arrival window when you book and keep you updated by SMS.
No call-out fee during business hours. We diagnose the problem and give you a fixed quote before any work starts — if you don't go ahead, you owe nothing. After-hours emergencies carry a fixed attendance component that's credited against the repair.
Fully. We operate under NSW plumbing and gas licence 496469C and carry comprehensive public liability insurance. Every gas job comes with a compliance certificate, and commercial clients get all documentation for their records.
Yes — offices, retail, hospitality, industrial sites and strata blocks across Sydney. We run scheduled preventative maintenance programs, handle backflow and TMV compliance, and give contracted sites priority 24/7 response.
Our workmanship is guaranteed on every job, and installed products carry their full manufacturer warranties — which we register for you. If something we've fixed ever plays up, call and we'll make it right.
// RESIDENTIAL PLUMBING18 QUESTIONS
Drains, hot water, taps and renovations — the questions we get asked in Sydney homes every week.
Blocked DrainsVIEW PAGE →
Same-day for most of Sydney if you call before early afternoon, and we run 24/7 emergency callouts for overflowing sewers. Most standard blockages are cleared within the hour once we're on site.
Repeat blockages usually mean tree roots, a cracked or collapsed pipe, or a belly in the line — not bad luck. A CCTV camera down the drain shows the cause in minutes, and we give you the footage and a written repair quote.
Both. Electric drain machines suit internal fixtures, while high-pressure jet rodding is far more effective on sewer and stormwater lines because it scours the full bore of the pipe instead of drilling a hole through the blockage.
Sometimes — policies often cover damage caused by the blockage rather than the clearing itself. We provide CCTV footage and written reports that you can submit with a claim.
Keep fats and oils out of the kitchen sink, fit strainers on shower and floor wastes, and flush nothing but paper down the toilet — wet wipes are behind a huge share of Sydney blockages even when labelled flushable. If mature trees sit near your sewer line, an annual jet-rod and root treatment costs far less than an emergency callout every winter.
Everything on your side of the connection point to the main is the property owner's responsibility, which covers most blockages we attend. When our camera shows the fault sitting in Sydney Water's main or a council stormwater asset, we tell you straight away and point you to the right authority instead of charging you for a repair that isn't yours.
Hot Water SystemsVIEW PAGE →
In most cases, yes. We carry common tank and continuous-flow sizes, and if you call in the morning we can usually have the new system running the same day anywhere across Sydney.
A tank over 8–10 years old that's leaking from the cylinder is a replacement — repairs are money down the drain. Faults in valves, thermostats or elements on younger units are usually worth repairing. We price both options so you can decide.
Heat pumps are the cheapest to run and attract NSW rebates, gas continuous flow suits homes already on gas, and electric storage is the cheapest upfront. We'll size the right option for your household rather than the one with the biggest margin.
Yes — we'll install a compliant unit you've purchased, though supply-and-install usually works out similar in cost once warranty and delivery are counted, and it means one company is responsible for everything.
Storage tanks benefit from a service every five years — the sacrificial anode is checked and replaced if worn, which can add years to the cylinder's life, and the temperature-pressure relief valve is tested. Continuous-flow units want a flush and filter clean around the same interval. It's cheap insurance: most tanks that fail early were simply never serviced.
Cold inlet water in a Sydney winter can be ten degrees lower than summer, so the system works harder to reach the same temperature and a marginal tank suddenly feels too small. Longer showers in July don't help either. If winter shortfalls happen every year, the unit is undersized for the household — we can size a replacement properly rather than guessing.
Bathroom & Kitchen PlumbingVIEW PAGE →
Either. We can supply quality tapware and toilets at trade pricing with warranty handled by us, or install fixtures you've already bought — we'll tell you honestly if something you've picked is likely to give trouble.
We handle all plumbing stages of a renovation — strip-out, rough-in, and fit-off — and work in with your builder, waterproofer and tiler. We don't tile or waterproof ourselves, but we can recommend trades we trust.
It's usually a failed waterproofing membrane, a cracked shower base or a leaking valve in the wall. We pressure-test the pipework first, so you never pay to re-tile a bathroom when the actual fault was a worn valve.
Taps, toilets and appliance connections are usually same-week, often same-day. Small jobs are welcome — there's no minimum job size and no call-out fee.
For an apartment, usually yes once the work goes beyond like-for-like fixture swaps. Anything touching waterproofing, relocating fixtures or altering common pipework generally needs owners corporation consent, and some buildings require it in writing before trades start. We've worked under plenty of strata by-laws and can supply the licence details, insurance certificates and scope description your strata manager will ask for.
Braided flexi hoses are one of the most common causes of internal flooding in Australian homes — they fail without warning and release mains-pressure water until someone shuts it off. Check them for rust spots, fraying or kinks, and replace any hose older than about ten years. While we're at your place for other work, we'll happily inspect every flexi in the house at no charge.
// COMMERCIAL & INDUSTRIAL18 QUESTIONS
Compliance, maintenance programs and drainage surveys for offices, strata blocks and industrial sites.
Commercial & Strata MaintenanceVIEW PAGE →
Offices, retail, hospitality, medical suites, warehouses, schools and strata blocks across Sydney. If it has water, gas or drainage, we can put it on a program.
Yes. We start with a site audit, inherit your compliance calendar and flag anything overdue — the handover usually takes one visit.
Every visit produces a digital report with photos, and annual testing (backflow, TMV, eyewash stations) is lodged with the right authority automatically. Auditors love us.
Priority 24/7 response — typically under an hour for emergencies inside our Sydney service area, with a make-safe first, then a fixed quote for the permanent repair.
As a rule of thumb, pipework serving a single lot is the owner's cost, while shared risers, common drains and anything within common property sits with the owners corporation. Boundaries blur in older strata plans, so we photograph the fault, identify where it sits relative to common property, and give the strata manager a report that settles the question before invoices fly.
Sydney Water sets the pump-out frequency in your trade waste agreement — often quarterly for a busy commercial kitchen, though light-use sites may be approved for longer intervals. Letting it slip risks blocked drains mid-service, odour complaints and penalties on your agreement. Our programs track the schedule, coordinate the pump-out contractor and keep the paperwork audit-ready.
Backflow Prevention & TMVVIEW PAGE →
Yes — Sydney Water requires testable backflow prevention devices to be tested every 12 months by an accredited plumber, with results lodged. Fines apply for lapsed devices, and we make sure you never lapse.
A thermostatic mixing valve delivers water at a safe, stable temperature — mandatory in aged care, childcare, schools and healthcare, and best practice in commercial amenities. They must be serviced every 12 months.
We tell you on the spot, quote the repair or replacement, and in most cases rebuild and retest the device in the same visit so your compliance never lapses.
Yes — we consolidate all your devices into one register, align due dates where possible, and invoice once. Property managers typically save hours of admin a year.
Any connection where contaminated water could be drawn back into the drinking supply needs protection — think irrigation systems, fire hose reels, commercial kitchens, workshops with chemical use, or medical and dental suites. Sydney Water rates each property's hazard level, and the rating dictates the device type. Unsure where you stand? We'll audit the site and confirm exactly what's required.
Briefly, yes — testing a backflow device means isolating it for around 15 to 30 minutes per device, and a TMV service interrupts the outlets that valve feeds. On occupied sites we schedule around your quiet periods, stagger devices so the whole building is never off at once, and give tenants notice beforehand. Most occupants never notice we were there.
CCTV Drain InspectionsVIEW PAGE →
Clearing fixes the symptom; the camera finds the cause. If roots or a broken pipe are in the line, the blockage will return — the footage tells you whether it's a one-off or a structural problem that's far cheaper to fix now than after it fails.
Absolutely — cracked or root-bound sewers are among the most expensive hidden defects in Sydney's older suburbs, and standard building inspections never look underground. A survey before you buy can save you from a very expensive surprise.
The camera head carries a sonde we trace from the surface, giving location within centimetres and depth within about 5%. Repairs become a small keyhole excavation instead of digging up the yard.
Yes — every inspection includes the full recording and a written report, emailed the same day. It's yours for insurance claims, council submissions or negotiating a purchase price.
Allow 45 minutes to an hour for a typical house with accessible inspection openings — longer if we're surveying both sewer and stormwater or need to clear a blockage before the camera can pass. You're welcome to watch the monitor live while we work; most clients find it oddly fascinating. The recording and report land in your inbox before close of business.
Where mature trees sit over or beside an older clay sewer, an inspection every 12 to 24 months keeps you ahead of the roots — fine root intrusion shows up on camera well before it becomes a Sunday-night overflow. Pair the survey with preventative jetting and a root inhibitor treatment and many owners avoid excavation entirely for decades.
// EMERGENCY PLUMBING18 QUESTIONS
Burst pipes, gas leaks and blocked sewers — what to do first, and what happens when we arrive.
24/7 Emergency PlumbingVIEW PAGE →
Under an hour for most suburbs inside our Sydney service area, day or night. When you call, we give you a realistic ETA and SMS updates — not a vague 'sometime today'.
For water: turn off the main isolation valve (usually at the front boundary or water meter) — we'll talk you through finding it. For gas: turn off the meter valve, open windows, no flames or switches. Then leave the rest to us.
After-hours attendance carries a fixed callout component that's credited against the repair if you go ahead. The repair itself is quoted at the same fair rates as daytime — emergencies aren't an excuse to gouge.
Sudden burst pipes and resulting water damage are commonly covered. We document everything with photos and a written report, which is exactly what assessors ask for.
Anything you can't safely stop or contain: water you can't isolate, sewage coming up inside the house, any suspicion of gas, or a failed hot water system in a household with young children or elderly residents. If a bucket and a closed valve will hold it overnight, a next-day booking saves you the after-hours component — and we'll tell you honestly which one you've got when you call.
For genuine emergencies, NSW tenancy law lets tenants arrange urgent repairs — burst pipes, blocked toilets where there's no second toilet, gas leaks and failed hot water all qualify — and claim back reasonable costs up to a capped amount. Ring your agent first if you can reach them; if nobody answers and water is pouring through the ceiling, call us, keep the invoice, and notify the agent as soon as possible.
Burst Pipes & Leak DetectionVIEW PAGE →
Classic signs: a water bill jump with no change in habits, the meter spinning with every tap off, damp carpet or skirting, mould, or a warm patch on the floor (a hot water slab leak). A two-minute meter test confirms it.
Yes — acoustic ground microphones and thermal imaging locate slab leaks without breaking anything. Often the smartest fix is rerouting the failed section above slab rather than excavating it.
Usually just one small, precise opening at the leak point — that's the whole value of detection. We're replacing 'rip it up until we find it' with 'open exactly here'.
Many policies cover the cost of locating a hidden leak and the resulting damage, though not always the pipe repair itself. Our written detection report supports the claim either way.
High mains pressure is the quiet culprit in much of Sydney — anything consistently above about 500 kPa fatigues pipework, joints and flexible hoses. Add age-related corrosion in copper and galvanised lines, ground movement, and the occasional nail through a wall pipe, and failures follow. If we measure high pressure at your place, a pressure limiting valve at the meter is cheap protection for every pipe in the house.
Possibly — Sydney Water runs an allowance scheme for concealed leaks that can wind back part of the excess usage on your bill, provided the leak was genuinely hidden and repaired promptly by a licensed plumber. Applications need evidence of the repair, which is where our detection report and invoice come in. We'll flag it whenever your job looks eligible and give you the paperwork to apply.
Gas Fitting & Gas LeaksVIEW PAGE →
Turn the gas off at the meter, open windows and doors, don't operate switches or flames, and call us from outside on (02) 9606 4913. We treat suspected leaks as 24/7 emergencies.
No — in NSW all gas work must be done by a licensed gas fitter and certified. Uncertified work voids insurance and appliance warranties, and it's genuinely dangerous. We connect and certify it properly.
Yes — both, including converting appliances between fuels, bottle installations for homes without mains gas, and caravan or outdoor kitchen fit-outs.
It's the legal record that your gas work was done by a licensed fitter and tested safe. You'll want it for insurance, warranty claims and when you sell. We issue one on every job automatically.
Every couple of years is the accepted rule for heaters, cooktops and gas hot water — and annually for old flued heaters that get heavy winter use. Servicing checks burner pressure, combustion and carbon monoxide spillage, which you can't see or smell until it's a serious problem. Book heater servicing in autumn rather than the first cold week of winter, when every gas fitter in Sydney is flat out.
It's a smart move, particularly on older houses where lines may be undersized, corroded or carrying long-abandoned dead legs. A pre-purchase gas inspection includes a pressure-drop test of the whole installation, a look at appliance condition and flueing, and a written summary for your solicitor or building report. The cost is trivial next to discovering after settlement that the heater fails a safety check.
// SERVICE AREAS60 QUESTIONS
Local questions from each of the 12 Sydney regions we patrol.
Eastern SuburbsVIEW PAGE →
We typically reach Bondi, Randwick and surrounding suburbs within 45 minutes for emergencies, and offer same-day standard bookings across the region.
Constantly. We know the quirks of Federation-era plumbing — original clay sewers, galvanised water lines and shared party-wall drainage — and how to fix them without wrecking heritage fabric.
Yes, from small art-deco blocks to large complexes — common property maintenance, backflow and TMV testing, and 24/7 emergency response for building managers.
Urgent problems like burst pipes or a failed hot water system are the landlord's responsibility to fix promptly, so contact your property manager first. When agents are unreachable and the issue is genuinely urgent, NSW tenants can arrange the repair themselves and seek reimbursement of reasonable costs. Either way, we attend rentals across Coogee, Kingsford and Randwick daily and invoice whoever the tenancy paperwork says we should.
Strongly, yes. Terraces in Paddington, Woollahra and surrounding streets often still run on their original clay sewers, and a cracked or root-choked line is one of the priciest defects a building report will never find. A camera survey before exchange costs a few hundred dollars and gives your solicitor something concrete to negotiate with — or the confidence to proceed.
Inner WestVIEW PAGE →
Yes — our compact jetting gear is built for rear lanes and tight terrace access, and we're used to coordinating with neighbours on shared boundary drains.
Daily. Grease arrestor programs, under-sink pump cleanouts, gas appliance certification and after-close maintenance visits that don't cost you trading hours.
Usually the culprit is original galvanised pipework that's corroded internally. We confirm it with a pressure test, then quote a re-pipe in modern materials, staged to keep water on each night.
Regularly — the apartment corridor through Burwood, Strathfield and Ashfield keeps our strata crews busy with common-property leaks, riser valve replacements, backflow testing and hot water plant maintenance. Building managers get a single contact, digital reports after each visit and 24/7 emergency cover, whether the block is a six-pack walk-up or a new tower.
All the time. Much of Balmain, Rozelle and Annandale sits in conservation areas, so we run new services along routes that spare original fabric, reuse existing penetrations where possible and leave sandstone and brickwork untouched. When a job needs council input, we've been through the process often enough to keep it painless.
Northern BeachesVIEW PAGE →
Yes — Manly through to Palm Beach, including Frenchs Forest and the forest suburbs. Emergency response typically lands within the hour, even mid-peninsula.
That's classic undersized or blocked roof drainage. We clear, camera and re-size gutters, downpipes and stormwater lines so they handle a proper east-coast low, not just a shower.
Stainless-tank units and heat pumps with coated coils fare best in salt air, positioned out of direct spray. We'll site and spec the system for your exact exposure.
Yes — the semi-rural blocks through Terrey Hills and parts of Belrose are regular territory. Pressure pump replacements, mains-to-tank changeover valves, filtration housings and leaking tank fittings are the usual jobs, and we carry common pump spares so most repairs finish in a single visit. If the original installer has long since retired, we'll pick the system up from whatever documentation exists.
Happily — beachside strata is a big part of our Northern Beaches workload. Salt air shortens the life of common hot water plants and roof plumbing, so blocks in Dee Why, Manly and Collaroy benefit from scheduled inspections rather than waiting for failures. We provide the compliance testing, photographic reports and after-hours response building committees ask for.
North ShoreVIEW PAGE →
Often, yes — CCTV locating pinpoints the fault so repairs are keyhole excavations, and pipe relining can fix root-damaged sections with no digging at all.
Yes — we're the plumbing trade on renovations across the North Shore, from ensuite refits in Roseville to whole-house projects in Mosman, coordinating cleanly with your builder's schedule.
Typically 45 minutes or less to the lower North Shore and around an hour to Hornsby and the upper suburbs, 24/7.
Yes — the tower growth through Chatswood, St Leonards and Crows Nest has made strata work a core part of our North Shore operation. We handle common-property repairs, annual backflow and TMV testing, hot water plant servicing and emergency response, with the induction paperwork and insurances building managers require sorted before the first visit.
That knock is water hammer, and it's common in the older homes of Killara, Turramurra and Wahroonga where original pipework was never clipped to modern standards. Fast-closing mixer taps and appliance solenoid valves make it worse. Fixes range from securing loose pipes and fitting hammer arrestors to installing a pressure limiting valve — usually a small job that ends years of noise.
Hills DistrictVIEW PAGE →
Yes. We diagnose the defect, document it with photos and CCTV footage where relevant, and issue a written report you can put in front of the builder or Fair Trading.
Absolutely — pressure pumps, rainwater switching, long poly mains and stock troughs are regular work for our Hills crews in Dural, Galston and Glenhaven.
For 4+ bathrooms we usually spec twin continuous-flow units or a large heat pump with a buffer — sized properly so showers never go cold. We calculate it from your fixtures, not a guess.
Frequently. New release areas around Kellyville, North Kellyville and Box Hill can carry mains pressure well above what fixtures are designed for, which shortens the life of flexi hoses, mixer cartridges and hot water valves. A pressure reduction valve at the meter brings everything back within range — we test your static pressure free of charge on any visit.
Plenty of Castle Hill, Baulkham Hills and Winston Hills housing dates from the 1970s and 80s, and those original bathrooms are being renovated street by street. We handle strip-out, rough-in and fit-off, upgrade tired galvanised or early copper pipework while the walls are open, and coordinate with your builder so the plumbing stages never hold up the tiler.
South West SydneyVIEW PAGE →
Yes — this is our base region, which is why our response times here are the best in our network. A Liverpool emergency can often see a truck inside 30 minutes.
Extensively — trade waste compliance, grease arrestors, backflow testing, roof and stormwater plumbing, and scheduled maintenance across the Moorebank and Ingleburn industrial precincts.
Almost always. Being based locally with stocked trucks means a dead system reported in the morning is usually replaced and running by the evening.
Yes — as mains reach the Austral and Leppington acreage belt, we manage the whole changeover: drainage design, the connection itself, decommissioning the old septic tank properly and any yard reinstatement afterwards. Timing depends on when the authority makes your street's connection available, so send us your notice and we'll give you a fixed quote for the private works side.
Across Liverpool, Campbelltown and Prestons we look after exactly those facilities — thermostatic mixing valves serviced annually, backflow devices tested and lodged, hot water delivered at compliant temperatures and everything documented for your next audit. Facility managers get reminders before due dates so certification never lapses, and there's one contractor, one register and one invoice across all your sites.
Western SydneyVIEW PAGE →
Yes — the whole western corridor from Auburn out to Glenmore Park, with crews positioned so emergency response stays around the hour mark even at the Penrith end.
That's standard for us in Parramatta — inducted technicians, after-hours access protocols and works scheduled so tenants never see a closed bathroom sign.
Brown or rusty water usually means corroding galvanised pipes. We confirm it, then quote a staged re-pipe in copper or PEX — most homes are done in two days with water on each night.
Yes — the health precinct around Westmead and Wentworthville brings steady work in TMV servicing, backflow testing and fixture maintenance for medical suites, dental clinics and allied health rooms. We understand infection-control expectations, work around appointment schedules and keep the compliance records practice managers need on file, with reminders ahead of every due date.
Winter out west bites harder than the coast, and gas heating is everywhere from Blacktown to Glenmore Park. Our licensed gas fitters install heater points and bayonet fittings, connect and certify new units, and service older heaters — including the combustion and spillage checks that catch carbon monoxide risks before the cold sets in. Book in autumn to beat the June rush.
Sydney CBDVIEW PAGE →
Yes — most of our CBD work is scheduled after hours by design. We handle building inductions, access permits and lift bookings, and leave sites presentation-ready.
All over the CBD — grease trap programs, blocked kitchen drains cleared before service, gas compliance and emergency response that understands a Friday night matters.
Generally: inside your lot is yours, shared risers and common pipes are strata's. We work for both owners and building managers daily and can tell you within minutes whose problem a leak actually is.
Constantly — Zetland, Chippendale and the southern fringe have added thousands of apartments, and new buildings bring their own plumbing patterns: pump room maintenance, defect-period investigations, riser isolation for lot renovations and hot water plant servicing. We report in the format building managers and owners corporations expect, with photos attached to every job.
Yes — tenancy fit-outs across the CBD, Barangaroo and Surry Hills are familiar ground. We rough-in kitchenettes and end-of-trip facilities, extend risers under permit, and coordinate with your shopfitter and the building's engineer so base-building systems are never compromised. Works are staged outside business hours where the lease demands it, and certification is supplied for the defects file.
FairfieldVIEW PAGE →
Fairfield sits close to our South West base, so emergencies here are among our fastest callouts — usually inside the hour, with same-day booking for standard jobs.
Regularly. Grease arrestor cleaning and scheduling, trade waste compliance paperwork for Sydney Water, drain jetting and after-hours work so we're not in the way during service.
In Fairfield the usual answer is soil movement. Clay ground shifts through the year and pulls old earthenware joints apart, so debris catches at the same point every time. A camera survey finds the displaced joint, and relining fixes it without digging up the yard.
Yes — sewer and water connection, hot water sizing, and the compliance certificates your certifier will ask for. We check the existing junction has the fall and capacity to take the extra load before we quote, which avoids the classic problem of two dwellings sharing a line that was only ever sized for one.
Our crews cover a range of languages across the team, and Fairfield is a region we work in constantly. If you'd prefer to arrange the job in another language, mention it when you call and we'll match you with a plumber who can.
Ryde & Macquarie ParkVIEW PAGE →
Yes — commercial maintenance, backflow prevention and TMV testing with certificates, plus emergency response for building managers. We schedule around tenant hours so the work doesn't interrupt trading.
Regularly. We work with owners corporations and strata managers across the newer Meadowbank and Melrose Park buildings — common property risers, pump wells and leak investigation, with written reports for defect claims where they're needed.
Ryde is well covered by our northern crews. Most emergencies see a van inside the hour, and standard jobs booked before early afternoon are usually done the same day.
Almost every recurring blockage we clear in that pocket comes down to wipes and fat rather than the pipe itself. A camera survey between tenancies confirms whether the line is sound, and a short note to incoming tenants about what not to flush prevents most callouts. If the survey does find roots or a cracked joint, relining fixes it permanently.
Many do eventually. Interwar and post-war homes around there were plumbed in galvanised steel, which corrodes internally and slowly strangles flow. If your pressure has dropped or the water runs rusty first thing in the morning, a pressure test will tell you whether it's a single failing section or time for a full repipe.
St GeorgeVIEW PAGE →
Most St George emergencies see a van inside the hour, and standard bookings across Hurstville, Kogarah and Rockdale are usually same-day if you call before early afternoon.
It's common there, but it isn't something you have to live with. Those streets sit very low relative to the bay, so stormwater lines have minimal fall and silt up easily. A camera survey shows whether the line is simply blocked, has a belly holding water, or is genuinely undersized — the fix is different for each, and only one of them needs excavation.
Salt air. Within a few streets of Botany Bay, tanks and external fittings corrode considerably faster than inland. Checking the sacrificial anode every couple of years costs very little and routinely adds years to a tank's life — most people never have it done and replace the whole unit instead.
Yes — from small interwar blocks to the newer towers. Common property maintenance, backflow prevention and TMV testing with certificates, and 24/7 emergency response for building managers and strata committees.
Worth it. Homes through that pocket often still run their original clay sewer beneath established gardens, and a root-choked or cracked line is an expensive defect that a standard building report will never look for. A camera survey before exchange gives you either something concrete to negotiate on or the confidence to proceed.
Sutherland ShireVIEW PAGE →
We run crews through the Shire daily. Emergencies around Miranda, Caringbah and Sutherland typically see a van inside the hour, with same-day standard bookings across the region.
Yes. Around Menai, Illawong, Bundeena and the river fringe we work on pump-out systems, septic tanks and absorption trenches — servicing, repairs and advice on changeover if mains sewer reaches your street.
Usually, yes — and in the Shire that matters more than most places. Excavating through sandstone is slow and costly, so we camera the line first and reline wherever the host pipe allows it. That puts a new pipe inside the old one through existing access points, with no trench across your yard.
Salt air. Coastal streets corrode tanks and external fittings considerably faster than inland suburbs. Having the sacrificial anode checked every couple of years is inexpensive and routinely adds years of life — most people skip it and end up replacing the whole system early.
Treat it as urgent. On the steep blocks around the Woronora and Port Hacking there's no gravity fall to fall back on, so once the pump stops the well fills and backs up toward the house. Call us straight away, stop using water where you can, and we'll get someone out — we carry common pump spares on the trucks.
