Sydney plumbing questions, answered.

Turn the water off at the main meter (usually a blue-lidded box near the front boundary) — one clockwise quarter-turn on the handle stops the water. Then flip the switch on your hot water system to stop it refilling an empty tank. Call us on 0432 304 609. Move valuables, towel the floor, and don’t touch any wet electrical fittings.

Honestly, it depends on what’s on for the day. We’re a local Sydney plumbing team (not a 24/7 dispatch service), so when you ring we’ll check the day’s bookings and tell you straight whether we can get there today, tomorrow, or whether a closer plumber would serve you better. The drive from our Rydalmere yard is 20–40 minutes to most mid-ring suburbs and 60–90 minutes to the outer rings — but the van may be coming from a previous job, so we’ll give you a realistic window when we book.

Don’t turn anything electrical on or off, don’t strike a flame. Open doors and windows for ventilation, turn the gas off at the meter if safe to reach (clockwise quarter-turn), and leave the building. Call Jemena on 131 909 if the smell is strong, then call us. Do not go back inside until it’s cleared.

If water is actively coming over the rim and onto the floor, yes — turn off the isolating tap behind the toilet (clockwise) and stop flushing anywhere in the house. If the whole main sewer is blocked, other drains will gurgle when the toilet is used. Call us and we’ll tell you straight whether we can fit it in today or point you to a plumber who can get there sooner.

There are usually two places: the Sydney Water meter at your front boundary, and an isolation valve near where the water enters the house. Either stops water to the whole property. Individual fixtures often have their own isolators (behind toilets, under basins) which we recommend to clients during renovations.

Actively escaping water, gas smell, main-sewer blockage backing up into the house, a leaking hot water tank, or anything threatening safety or major property damage. Dripping taps, slow drains and non-urgent hot water faults are not emergencies — we’ll book those in quickly but won’t charge emergency rates.

No — and we’d rather be upfront than pretend. We’re a booking-first Sydney plumbing team that works through scheduled jobs each day. We’ll prioritise urgent work where we can during business hours and for regular commercial/strata clients we’ll take after-hours calls, but for one-off overnight or weekend emergencies a dedicated 24-hour plumber will usually get there quicker. We’ll point you in that direction honestly on the phone.

Electric storage tanks: 10–15 years. Gas storage: 8–12 years. Gas continuous flow: 15–20 years. Heat pumps: 10–15 years. Solar: 15–20 years on panels, 8–10 on boosters. Hard water and high chlorine levels in some Sydney suburbs can shorten these — replacing the anode rod at year 5 roughly doubles the life of a storage tank.

Under 8 years old and the failure is a part (thermostat, element, TPR valve, thermocouple) — repair. Over 12 years old, or leaking from the tank base itself — replace. Anything in between, we’ll weigh the repair cost against remaining life and give you a straight answer.

For a 4-bedroom Sydney home with natural gas connected, a gas continuous-flow unit (Rinnai Infinity 26 or Rheem Metro) is the most reliable and lowest-fuss. No connection to gas? A heat pump (Sanden, Reclaim, or Rheem) will beat an electric tank on running cost by 70% and attracts federal rebates.

On a storage tank it usually means the bottom element or thermostat has failed (in electric), the dip tube has snapped and cold water is short-circuiting hot water to the outlet, or the tank is ready for replacement. We’ll diagnose it without a call-out fee on a scheduled job.

For most Sydney households replacing an electric tank — yes. Federal STC rebates and NSW energy rebates often cover 30–60% of the install cost, and running costs are typically ∼70% lower than electric storage. The best brands (Sanden, Reclaim) have 10-year warranties; avoid the cheapest imports. Full breakdown in our heat pump vs gas vs electric guide.

Yes. Rheem, Rinnai, Dux, Bosch, Aquamax, Vulcan, Sanden, Reclaim, Thermann, Stiebel Eltron and more. We stock the common parts for all of them on the van.

The temperature-and-pressure-relief valve is a safety device on every storage hot water tank. A slow drip is normal during the daily heat cycle. A steady stream means the valve has failed or the tank is over-pressurising — both jobs for a plumber, not DIY.

On running cost alone, heat pumps generally come out cheapest, followed by solar with electric boost, then gas continuous flow, then gas storage, then electric storage. Actual figures depend on your tariff, household size and usage patterns — tariffs change, so we don’t quote a hard number here. Whether a system wins overall depends on your install cost after any rebates you qualify for. Our hot water comparison guide walks through the trade-offs.

A like-for-like changeover (gas-to-gas or electric-to-electric in the same spot) is typically a half-day — 3–5 hours on site. Switching fuel types or relocating the unit (e.g. electric tank to a heat pump in a new position) usually runs a full day because of new electrical wiring, condensate drainage and a tempering valve to AS 3500. We aim to leave you with hot water that night.

Sometimes — but heat pumps need air clearance to work efficiently. Most need at least 300–500 mm clear above and around the unit, and they push out cool air, so under-eaves or alongside an outdoor area is best. They also need power and condensate drainage. We size up the spot before quoting and tell you straight if it’ll fit or needs relocating.

Repeat blockages nearly always mean tree roots have entered a cracked earthenware sewer pipe — common in Sydney homes over 30 years old — or a joint has dropped and food/waste is catching. A once-off clear is a band-aid. A CCTV camera survey shows you exactly why it’s happening.

Supermarket drain chemicals rarely clear a real blockage and can damage old pipes, seals and chrome fittings. At best they soften a localised grease plug. For tree roots, grease traps and kitchen blockages they’re useless. Hot water and dish soap will do as much for a slow kitchen sink.

We run a waterproof camera on a flexible rod down the drain, recording video as we go. You get to see exactly where the blockage is, what caused it, and the condition of the pipe on either side. We measure the depth and supply the footage — invaluable before any dig or reline.

We pull an epoxy-soaked liner through the damaged pipe, inflate a bladder to press it to the pipe walls, and cure it in place — creating a new, seamless, root-proof pipe inside the old one. No trench, no lawn demolition. Lasts 50+ years on most manufacturers’ warranties.

From inside the house to the connection point at Sydney Water’s main (usually at the front boundary), the pipe is the homeowner’s. From there it’s Sydney Water’s. If your blockage turns out to be in their section we’ll give you the CCTV footage to escalate.

Empty the trap under the sink first (bucket underneath, unscrew the two collars, clean it out). That fixes about half of kitchen-sink slowdowns. If not, it’s further down the line and grease build-up is the likely culprit — a water jetter will clear it properly where a plunger won’t.

Usually a dry or failed trap letting sewer gas up, a partially blocked vent, or decaying food/biofilm in the line. Run water in every drain for 30 seconds to refill traps first. Persistent smells need investigation — they often signal an upstream problem.

For a typical Sydney house run (10–25 metres of sewer), the actual install is one day on site — CCTV survey, hydro-jet clean, measure, install the liner, inflate the bladder and cure. The cured-in-place liner is fully usable within a few hours. We schedule access and toilet downtime so you’re only without facilities for 4–6 hours mid-day. Relines are warrantied for 50 years.

Top causes in order: a running toilet (the silent leak — up to 60 L/hr), an irrigation valve stuck open, an undetected pipe leak in the slab or yard, a faulty hot water TPR valve dripping continuously, or a misread meter. Take a meter reading at night, don’t use any water for 2 hours, then check it again — movement = leak. Full diagnostic walkthrough in our 8 causes of a water bill spike guide.

No. In NSW all gas connections must be done by a licensed gas fitter and come with a NSW Gas Compliance Certificate. DIY gas work voids your home insurance and is a prosecutable offence under the Gas Supply Act. A cooktop install takes a licensed gas fitter 60–90 minutes.

It’s the NSW document a licensed gas fitter issues for any gas installation or modification. You’ll need to produce it when selling a home and your insurer may request it after any claim. We issue one for every gas job we do.

Have a licensed gas fitter service gas heaters and cooktops every 2–3 years. Continuous-flow hot water units benefit from a service every 3 years. If you ever smell gas, hear hissing, or see a yellow/orange flame instead of blue, that’s sooner not later.

Most current-model BBQs and ovens accept a conversion kit. We install the gas point, fit the conversion orifice, and pressure-test it. Some budget imports don’t have a conversion path — we’ll check before quoting.

If the smell is strong, ring Jemena on 131 909 (the Sydney gas distributor) — they attend free to make the site safe. Then call us on 0432 304 609 to locate and repair the fault. If the smell is faint, call us directly.

Almost never. New residential gas pipework is a notifiable plumbing job lodged through NSW Fair Trading by your licensed gas fitter (Form 7), not a council DA. Council only enters the picture for very large works or commercial fit-outs in heritage or fire-rated buildings. Either way, the gas fitter is responsible for the lodgement, inspection by Sydney Water/Jemena where required, and the Compliance Certificate at the end.

A plumber is licensed for water, drainage and sanitary work. A gas fitter is licensed for gas pipework and appliances — a separate NSW licence with separate training. Most Sydney renovations need both: a plumber for the kitchen sink and dishwasher, a gas fitter for the cooktop. Many tradespeople (us included) hold both licences, but the work and the certificates are issued separately.

Yes — NSW plumbing licence, NSW gas fitting licence, backflow accreditation, fire services accreditation, and $20 million public liability insurance. Certificates of Currency are available on request for any commercial client.

Yes for most residential and commercial work. Phone diagnosis is always free. On-site quotes for straightforward jobs are free too — we only charge if the job needs a proper investigation (leak detection, CCTV survey) or is a specialist report.

Fixed price, not hourly, wherever we can. You get a written quote before we start, and that quote includes all the charges that apply to your job — labour, materials, call-out where relevant, disposal, any travel component for longer runs, and any after-hours loading if the work falls outside normal trading hours. Nothing extra gets tacked on at the end. If the job scope changes we stop, quote the variation in writing, and wait for your go-ahead before we resume.

Bank transfer, Visa, Mastercard (small surcharge) and Amex. For commercial account clients we offer 14- or 30-day terms after two successful invoices.

Absolutely. We’d rather sort your tap washer today than lose you as a customer later. Small jobs are how you find out whether a plumber is actually good.

12 months workmanship guarantee on everything we touch. Materials carry the manufacturer’s warranty. If something we installed fails in the warranty period we come back and make it right at no cost to you.

Every Sydney suburb — we’re based in Rydalmere (NSW 2116) which puts us central to Parramatta, Ryde, Eastwood, the Hills, and the Inner West. Eastern Suburbs, Sutherland Shire, Northern Beaches and the full metropolitan area are all regular routes.

Yes — use the contact form or email info@southernstarplumbing.com.au. Include photos if you have them — it helps us scope the job and load the right parts on the van.

Saturday mornings (7am–12pm) are normal trading hours for booked work. Sundays, public holidays and late evenings we’re generally not out on the tools unless it’s for a regular commercial client or a genuine emergency — and work done outside normal hours carries an after-hours rate. Whatever the time slot, the rate that applies will be shown on your written quote before we start.

Every NSW plumber and gas fitter has a public licence number. Search it free at verify.licence.nsw.gov.au — you’ll see the licence type, status (active/expired/cancelled), and the categories they’re licensed for (plumbing, drainage, gas fitting). It’s also worth checking ABN registration at abr.business.gov.au and that they hold current public liability insurance. Any reputable plumber will give you their numbers without hesitation.

For larger jobs — renovation rough-ins, full hot water replacements, anything that touches multiple trades — yes, get 2–3 quotes. But compare like-for-like: same brand, same scope, same disposal arrangements, and the same compliance certificates included. The cheapest quote is rarely the cheapest job once variations come in. For straightforward one-off repairs, multiple quotes usually cost more in your time than they save.

It depends entirely on the job — access, scope, parts, and whether it’s in normal hours all matter. Rather than charge by the hour, we quote a fixed price in writing before we start so you know exactly what you’re paying. Our plumber pricing guide talks through how different jobs are priced and what an honest quote should include. The only accurate price for your job is one we give you in writing for your specific situation.

Because “the same job” often isn’t. Cheap quotes usually skip the compliance certificate, use lowest-grade fittings, leave the old unit for you to dispose of, or don’t include testing and commissioning. Always compare itemised inclusions, not just the headline number.

For quoted work the call-out is rolled into the fixed price — what’s on your quote is what you pay. For urgent attendance where the scope can’t be confirmed until we arrive, a single attendance fee applies (credited against the repair if you proceed). After-hours, weekend and public-holiday attendance carries a higher rate. The rate that applies to your job will always be set out in writing before we start.

Yes. Work done outside normal trading hours — evenings, Sundays, public holidays, and urgent after-hours attendances — carries an after-hours rate. We’ll tell you on the phone whether your job falls into that category and what the rate is, and it will form part of the written quote before any work starts. No hidden surcharges at the end of the job.

Yes — a 10% discount on labour for pension and concession card holders. Just mention it when you book.

Yes — our minimum charge is typically 1 hour of on-site time within normal trading hours, and a higher minimum for after-hours attendance. We’ll confirm what applies when you book, and it forms part of your written quote.

For most Sydney suburbs the travel component is already rolled into the fixed-price quote. For longer runs, regional jobs or work outside our usual service area we may include a separate travel line in the quote — you’ll see it before you accept, never as a surprise on the invoice.

It depends on the brand and model you choose, the complexity of the install (like-for-like vs relocation, electrical changes, condensate drainage), and any rebates you qualify for. Federal STC rebates and the NSW Energy Savings Scheme can take a meaningful chunk off the out-of-pocket cost. We’ll size the right unit for your home, calculate the rebates you’re eligible for, and give you a written, itemised quote. Our hot water buyer’s guide walks through what affects the final number.

Pipe relining is priced per metre of pipe, with a separate setup fee that covers the CCTV survey, hydro-jet preparation and bladder hire. The total depends on pipe diameter, length of the run, depth, the number of junctions and access. Relining is usually cheaper than excavation once you account for reinstating lawn, driveway or paving — but the only meaningful number is one based on your actual CCTV footage. We’ll survey, measure and quote in writing before any work starts.

The biggest cost variable is the toilet you choose — close-coupled, wall-faced, wall-hung, or a concealed-cistern smart suite all sit at very different price points before any plumbing labour. Then there’s whether the new pan goes back in the same position, or the soil pipe needs relocating. Removal and disposal of the old unit is included in our quote. Send us a photo of the existing toilet and we’ll quote the swap in writing.

A like-for-like mixer swap on a standard sink is usually a quick job, but the price depends on the tap you’ve chosen (which can range widely), whether the existing isolators are still good, and the access under your sink. We quote a fixed all-in price before we start — tap, fitting, isolators if they need doing, testing and clean-up.

A reputable plumber’s quote already has the fat trimmed — what you can negotiate is the scope, not the rate. Combining several small jobs into one visit, supplying your own taps/toilets/heaters, or scheduling out of peak weeks (Christmas/EOFY) genuinely lowers the bill. Pressuring a quote down 30% usually just gets corners cut on parts or the compliance certificate.

Regularly. Hot water, fire hose reels, stormwater, common-property drainage, TMV testing, backflow — we handle the lot. Invoices can be split between owner and common property with appropriate scope notes.

Backflow prevention stops contaminated water siphoning back into the drinking-water supply. In Sydney it’s compulsory for commercial properties, medical premises, any boundary with chemicals/dental/veterinary, and certain residential setups (e.g. swimming pools with fill lines). Annual testing is a legal requirement — we can do it.

Yes — childcare, aged-care and medical properties must have TMVs maintained and tested annually (AS 4032.3). We test, certify, and keep your records audit-ready.

Section 73 applications for new water/sewer connections in NSW go through Sydney Water directly, but we do the on-site civil plumbing portion and coordinate with the accredited WSC. Happy to walk developers through the process.

Yes — weekly. Food outlets, hospitality, pharmacies, barbers, dental and beauty. We work to the shopfitter’s program and handle water, waste, gas, backflow and compliance documentation.

It depends on the device type, size and hazard class, how many devices are on site, and accessibility. The annual test always includes the report lodged with Sydney Water. Multiple devices on the same site work out cheaper per device than a single one. If a device fails the test, it will need rebuilding or replacement, which we quote separately. Our backflow guide explains who needs them and why.

Annually under AS 4032.3 — thermostatic mixing valves on warm-water outlets in childcare, aged care, hospitals, schools and disability premises must be tested, certified and cartridges replaced where required. We do flow checks, temperature checks, valve servicing, and lodge the audit-ready paperwork. Sites with multiple TMVs (e.g. aged-care floors) get scheduled service runs to keep cost per valve down.

You’ll speak to a real plumber, not a call centre. We’ll diagnose what we can over the phone, book a time that suits, and give you an arrival window. For quoted jobs, we confirm the price in writing before we start work.

Where possible, yes — continuity matters, especially in a renovation or multi-visit job. For quick fixes it depends who’s closest.

Every job finishes with site left tidy, rubbish taken away, and paperwork handed over. Drop cloths go down in a home before work starts. Old hot water units, old toilets, and scrap pipe leave with us.

Yes — we can take photos or short videos of the problem, the access area, and the finished job. Handy for landlords, strata managers, insurance claims, and anyone who isn’t on site.

We love Google reviews — they help other Sydney homeowners find us. After your job we’ll send a quick link if you’re happy with the work.

Yes. For storm damage, flood, hidden leak, burst pipe or fire claims we issue a written plumber’s report covering the cause, date noticed, scope of repair, materials used, and photos before/during/after. Most Sydney insurers accept it directly. We can also quote remediation work alongside the temporary fix so the insurer has both numbers in front of them. A small report-writing fee applies for stand-alone reports without repair work — we’ll confirm it before we start.

Tell us — before paying, ideally. We carry a 12-month workmanship guarantee on everything we touch and we’d rather come back and put it right than see a bad review go up. If something isn’t to the standard you expected, ring 0432 304 609 or email info@southernstarplumbing.com.au and we’ll be back at no cost. Materials carry the manufacturer’s warranty separately.
