Backflow prevention

Backflow devices stop water from tanks, irrigation, pools or equipment flowing back into the drinking water supply. Many foothills homes have rainwater tanks connected to toilets and laundries, and many businesses have equipment that needs protection. Testable devices usually need testing every year, with reports lodged with the water corporation.

Rainwater tanks

Tanks connected to the house need a mains changeover device so you still have water when the tank runs low, and backflow protection so tank water never enters the mains. We install, service and repair pumps, changeover devices and backflow valves.

Water pressure

Homes high on the slopes can have low pressure, while those at the bottom of steep streets can have pressure high enough to strain tapware and hot water relief valves. We test pressure and fit pressure limiting valves or fix the cause of low pressure.

Scheduled maintenance

For landlords, property managers and homeowners who prefer to stay ahead of problems, we offer scheduled checks: drain camera inspections, hot water servicing, gas heater servicing, backflow testing and hose replacements.

Backflow on residential properties

Most homes do not need a testable backflow device, but some do. If your home has a rainwater tank connected to the house, an irrigation system with fertiliser injection, a fire sprinkler system or a pool with an automatic top-up, there may be a backflow risk. We check what is connected and tell you whether a device is required.

Annual testing

Where a testable device is installed, it needs to be tested every year by a licensed tester, and the results lodged with the water corporation. We test, repair and replace devices and can send you a reminder when the next test is due.

Preventive maintenance

Regular checks on hot water units, relief valves, pumps and drains help avoid emergencies. We can set up a maintenance schedule that suits your property.

Ferntree Gully ground and pipes

Ferntree Gully's ground changes as you climb towards the ranges: clay and silty loam on the lower streets, rockier, steeper ground near Upper Ferntree Gully and The Basin. Most homes built before the 1980s were connected with earthenware sewer pipe, and on a slope every joint moves a little over the years and lets roots in. Water service lines from the meter are often long and run through rocky ground or under established gardens. Stormwater has to be carried down the block and away from the house. We use cameras, locators and pressure tests to see what is happening before we dig.

    Backflow Testing and Maintenance: common questions

    Do I need a backflow device?

    Homes with tanks connected to mains, irrigation systems or pools often do. We can check.

    How often is backflow testing needed?

    Testable devices usually need testing once a year.

    Why is my water pressure low?

    Old galvanised pipe, a faulty stopcock or pressure valve, a leak or your position on the hill. We test to find out.
