Specialised plumbing & backflow prevention services in the Northern Rivers

At Northern Rivers Plumbing, Irrigation & Excavation Services, we’re proud to provide a range of specific services to the region. We offer specialised plumbing services and backflow prevention work to all properties in the region.

Ensuring your thermostatic mixing valves are in good condition is vital for proper temperature management and to prevent water scalding you in the shower. Our team has many years of experience in testing, surveying, installing and repairing all kinds of valves for your plumbing systems.

We’re also licensed to perform complete backflow prevention work. By installing a correctly designed and fitted backflow prevention device, we can ensure your water doesn’t flow back into the mains supply and contaminate it. Many councils have clear backflow prevention guidelines and mandates and require property owners to maintain and manage this themselves. We’re more than happy to check your system to ensure you meet your legal obligations.


Doing a renovation? At NRPI Excavations, we have a range of specialised equipment to allow us to easily excavate sloping and hard-to-access areas of your property. Our equipment includes:

Whether it’s excavation for renovation, driveways, landscaping, land clearing, new septic trench replacement, new sectic tanks or pipe replacement, our specialised equipment is able to get the job done.
