Why the two supplies must not mix the wrong way
A house that has both tank water and a town supply needs an arrangement so tank water, which may not be treated to drinking standard, cannot find its way into the town main. That usually means the right valves and, in many cases, a testable reduced-pressure zone or similar device. We check what is there and explain what the standard asks for, rather than assuming a single brass valve is enough.
Testing, not guesswork
Testable devices need periodic testing with a calibrated kit and a report. We test, repair or arrange a replacement if a device fails, and we retest after. We do not sign off a fail, and we do not test with a neglected kit.
Booking a test
Send a photo of the device — the body and the test cocks are enough — and ring 03 8658 7379. If you have been asked for a current test by the water authority or an auditor, tell us when the letter is due so we can book in time.
Do not bypass a failed device
If a device fails its test, do not bypass it to keep the tank online. We will quote a repair or a replacement and retest after, so the house stays supplied without putting the town main at risk. Ring 03 8658 7379.
Trafalgar pipes at a glance
Trafalgar sits on the Princes Highway in Baw Baw Shire, postcode 3824, between Yarragon and Moe, with farmland, weatherboard houses and larger rural blocks spreading toward Thorpdale, Willow Grove, Narracan and Trafalgar East. Many homes here run a rainwater tank as well as, or instead of, a town supply, and a good number still have a septic system rather than a sewer. Water services can be long runs down a gravel drive, and earthenware or PVC drains pick up roots from paddock and roadside trees.
We use cameras, locators, pressure tests and acoustic leak detection so we can see the pipework before anyone cuts a wall or opens a trench in a paddock lawn.
