Expert Reticulation Cut-Ins & Mains Connections

Yes, it is a strict legal requirement in Western Australia. While you or a landscaper can lay the PVC pipes and sprinkler heads in the garden, only a licensed plumber is legally permitted to cut into your property's main water supply.

Tapping into the scheme water involves altering the pressurised mains infrastructure. If this is done incorrectly by an unlicensed person, it can lead to catastrophic flooding, contamination of the public water supply, and immediate fines from the Water Corporation.

A cut-in is the physical plumbing connection where your new irrigation system joins your property's main water supply line. We typically perform this connection as close to the water meter as possible to ensure your reticulation system receives the maximum available water pressure before it branches off into your house.

During this process, we install a dedicated master isolation valve specifically for the reticulation. This is a crucial feature, as it allows you to completely turn off the water to your garden during winter or in the event of a sprinkler leak, without cutting off the essential water supply to your home or business.

Absolutely. Whenever a reticulation system is connected to the scheme drinking water supply, installing a backflow prevention device is mandatory. This valve acts as a one-way gate, stopping stagnant water, soil bacteria, and liquid fertilisers from being siphoned out of your garden pipes and back into the clean water you drink inside the house.

The specific type of backflow valve required depends on the hazard rating of your property. For a standard residential garden, a standard dual check valve is usually sufficient. However, if your system uses chemical fertiliser injectors or is on a commercial property, a higher-rated, testable device must be installed and certified annually by our team.

Low pressure across your sprinkler zones is often caused by an incorrectly sized cut-in pipe. If the pipe connecting the mains to your reticulation manifold is too narrow, it simply cannot deliver the volume of water required to pop up the sprinklers and achieve full coverage, leaving dry brown patches across your lawn.

Another common culprit in older systems is a failing master solenoid valve or a degraded backflow device that is internally restricting the flow. We can accurately test the static and dynamic pressure at your cut-in point to diagnose the exact location of the restriction, upgrading the pipework or replacing faulty valves to restore a strong, even spray to your garden.

Yes, the manifold is the heart of your reticulation system, where the main water supply splits off into the individual station valves. Because it is constantly under pressure and often exposed to the elements or buried in damp soil, the PVC joints and solenoid valves are highly susceptible to cracking and leaking over time.

We can excavate the damaged manifold, cut out the degraded sections, and rebuild it using heavy-duty, high-pressure PVC fittings. We ensure the new manifold is properly supported and housed in a protective valve box, safeguarding the electrical solenoids from dirt and moisture to significantly extend the lifespan of the entire system.
