How much does a plumber cost in Melbourne?

Most plumbers in Melbourne charge a call-out fee plus an hourly rate, or a fixed price per job. ATC Plumbing provides upfront quotes before starting work — you know the price before we start. As a guide, clearing a blocked drain starts from around $200–$450, hot water system replacement from $1,200, and general repairs from $150. See our full plumbing prices guide for detailed 2026 pricing.

Do I need a licensed plumber for all plumbing work?

In Victoria, all plumbing work must be performed by or under the direct supervision of a VBA-licensed plumber. This includes seemingly minor jobs like replacing taps, installing toilets, and connecting appliances to water supply. Unlicensed plumbing work is illegal and can void your home insurance. ATC Plumbing holds VBA Licence BPC #50694 — all work is performed by licensed tradespeople.

How do I know if I have a water leak?

Common signs of a hidden water leak include an unexplained increase in your water bill, damp patches on walls or ceilings, the sound of running water when all taps are off, or your water meter moving when nothing is in use. To check: turn off all water in the house, note the meter reading, wait 30 minutes without using any water, then check the meter again. If it's moved, you likely have a leak. ATC Plumbing uses acoustic and thermal leak detection to pinpoint leaks without unnecessary excavation.

How long does a hot water system last?

Gas storage hot water systems typically last 8–12 years. Continuous flow systems last 15–20 years. Electric storage systems last 8–12 years. Heat pump systems last 10–15 years. If your system is over 10 years old and starting to fail, replacement is usually more cost-effective than repeated repairs. See our full guide on hot water system lifespan.

What causes a blocked drain to keep coming back?

If your drain keeps blocking after being cleared, the cause is almost certainly structural — tree root intrusion at a joint, a cracked or collapsed pipe section, or pipe bellying where waste pools and accumulates. High-pressure jetting clears the blockage temporarily, but only a CCTV drain inspection identifies the underlying cause. Pipe relining is often the permanent fix — no excavation, 35-year warranty.

Is it safe to use chemical drain cleaners?

Chemical drain cleaners can clear minor blockages caused by grease or hair, but they won't clear root intrusion or structural blockages — and repeated use can damage older clay and PVC pipes. For persistent or recurring blockages, call a plumber for a proper assessment rather than repeatedly pouring chemicals down the drain.

What should I do in a plumbing emergency?

First: turn off the water at the meter to stop damage. The meter is usually near your front boundary under a small lid. Then call ATC Plumbing on 1300 282 758 — we answer 24/7 for genuine emergencies and can advise over the phone while we're on the way.
