Melbourne, VICPlumbing, drainage & gas

The half of your house you never see

Drains, gas lines and hot water live behind walls and under slabs. Getting them right the first time is cheaper than opening them up twice.

Why it matters

Nobody admires a drain until it stops working

A plumbing job is judged on the ten minutes of it you can see. The tap runs, the shower drains, the water is hot. Everything that decides whether it stays that way happens earlier, in a trench or inside a wall, and gets covered up before anyone photographs it.

That is the part worth paying attention to. A drain laid at the wrong fall works for a season. A gas line sized for the wrong appliance load works until the day it does not. Pipework that carries its own weight on the fittings will eventually find the weakest one.

Getting it right the first time is not craftsmanship for its own sake. It is the cheapest version of the job, because the alternative is paying someone to open it up again.

Read the work

A finished install tells you how it was done

You do not need a licence to judge plumbing. Pipe that runs square to the wall and sits in proper clips. Valves you can actually reach. Connections lagged where they should be. Nothing hanging off a fitting that was never meant to hold it.

The details on this hot water and tempering setup are the same details that decide whether the thing behind your wall lasts fifteen years or five.

One real job

High pressure feels like good pressure

This house was taking mains water at 700 kPa. Nothing had failed yet, which is exactly the problem. At that pressure every tap spindle, flexible hose, cistern inlet and appliance valve in the building is under constant strain, and the failures it causes look like bad luck.

A pressure limiting valve at the meter brought it down to a steady 500 kPa. Small part, short job, and it quietly stops the next decade of leaks that would otherwise get blamed on cheap tapware.

Testing your pressure takes minutes. A reading that comes back fine is still worth having.

Where we work

Melbourne and the north west

The jobs on record run from Greenvale down through Glenroy, Airport West, Essendon and Ascot Vale, plus drainage work over at Brighton Beach. Everything marked in brass is somewhere with completed work behind it.

All areas covered

How a job runs

No surprises, in either direction

  1. Tell us what is happening

    A message with the suburb, the problem and a photo. Most jobs can be narrowed down to one or two likely causes before anyone gets in a van.

  2. Looked at on site

    Quotes get worked out against your actual setup, not a price list. What is behind the wall changes the job, so the job gets priced after someone has seen it.

  3. Price agreed before work starts

    The price is agreed up front. If something genuinely unexpected turns up once things are open, work stops and you get a message before it continues.

  4. Installed, tested, commissioned

    Pipework tested before it is covered, appliances checked running rather than just connected, and the site left clean. Captions on completed jobs regularly note testing and commissioning.

Common questions

The things people ask first

If yours is not here, ask. A photo and a sentence usually gets a straight answer back.

Send a direct message on Instagram at @aquacore_plumbing, or use the enquiry form on this site. Include the suburb, what is happening, and a photo if you have one, because a photo usually answers three questions at once. No public phone or email is published yet.

Quotes are worked out on site against your actual setup and agreed before work starts. What is behind the wall changes the job, so the price follows what is actually there rather than a generic price list.

It depends on the age and what failed. A unit under about eight years old with a failed element or valve is usually worth repairing. A tank over ten years old that is leaking from the body is not, because the leak is the tank itself. Both options get quoted so the decision is yours.

Turn the water off at the meter, which is usually at the front boundary. Open a tap inside to drain the pressure out of the line, and keep anything electrical clear of the water. Then get in touch on Instagram. Finding your isolation valve before an emergency is half the battle.

Under AS/NZS 3500 and Victorian plumbing rules, static pressure at outlets inside a building should not exceed 500 kPa. Above that, taps, flexible hoses and appliance valves wear out years early. Testing takes minutes and a pressure limiting valve is a small part.

Yes. Gas appliance installs and changeovers are checked for leaks and commissioned before the job is finished. The published job record includes instantaneous gas hot water and appliance fit-off work.

Yes. Renovation rough-ins, drain repositioning and new service connections are covered, with pipework graded, tested and checked before walls or slabs are closed up.
