High water pressure silently damages your pipes, fittings, appliances, and hot water system. A pressure limiting valve (PLV) protects your entire plumbing system. We supply, install, and replace them across Melbourne.
Water pressure in Melbourne's mains supply can vary significantly, and when it's too high, it puts constant strain on every pipe, fitting, tap, and appliance in your home. A pressure limiting valve (PLV) is installed at your water meter to regulate incoming pressure to a safe level, typically between 350 to 500 kPa.
In Victoria, a functioning PLV is required by the Plumbing Regulations. If your existing valve is old, faulty, or missing entirely, you could be running at dangerously high pressure without knowing it. Our plumbers test your water pressure, advise on the correct valve rating, and install or replace the PLV in a single visit.
High water pressure often goes unnoticed until damage is already done. Look out for these signs.
Water hammer, loud banging when taps or appliances shut off, is often a direct symptom of excessive water pressure stressing your pipes.
High pressure wears out tap washers and ceramic cartridges prematurely. If taps keep dripping shortly after repair, pressure is often the cause.
If water blasts out at full force even when taps are barely open, your incoming pressure is likely too high and needs regulating.
Washing machines, dishwashers, and hot water systems are rated for specific pressure ranges. Excess pressure shortens their lifespan significantly.
High pressure causes relief valves on hot water systems to drip or discharge frequently. A sign that the incoming pressure is beyond the system's rated limit.
PLVs have a service life of around 8 to 10 years. If yours is old, corroded, or you're not sure one is installed, it's worth having it tested.
Simple, transparent, and done in one visit wherever possible.
We measure your incoming mains pressure to determine exactly what your system is running at and whether a new or replacement PLV is required.
We provide a fixed price for supply and installation before any work begins, no surprises on the invoice.
We install the correct valve at the water meter, set to the appropriate pressure, and ensure all connections are secure and compliant.
We re-test the pressure after installation to confirm it's sitting in the safe range before leaving your property.
We carry stock of common PLV sizes so we can test, supply, and install in a single visit, no need to order parts or rebook.
You'll know the full cost before we start. No hidden charges, no surprise costs.
All PLV installations meet Victorian plumbing regulations, so your home is protected and compliant.
