A pressure limiting valve (PLV) is a valve that reduces the pressure of the water which flows through it. Water mains pressure can reach extreme pressures and without a pressure limiting valve the pipes in your house could reach this pressure too.

The Australian Standards also state that any new buildings or extension work done to your plumbing requires the installation of a pressure limiting value. Failure to do this means that your building does not comply. The standards go on to say that ‘pressures above 500kPa can cause damage from water hammer, reduced life of appliances, taps and fittings, and cause excessive noise in the system.’

Firstly, The Plumbing Code of Australia and the Australian Standards (AS/NZS 3500) require that water pressure on your property must not exceed 500kPa. Water mains pressure may be considerably greater than this.

Water hammer arrestors are used to absorb the shock when water flowing in a piping system suddenly stops due to fast closing shutoff valves, dishwashers, and clothes washers. This action protects against annoying and potentially damaging effects of water hammer. We have models for residential and commercial applications. There are two types of water hammer arrestors, namely:

We understand that all of the plumbing jargon can be a little bit overwhelming. That is why we have decided to talk about a few of the most common plumbing terms and requirements in order to help you understand and feel comfortable with what may be happening or may need to be happening at your house. Today we are talking about a pressure limiting valve.

1) Piston Type - Piston constructed with copper tube with a piston internally that seals with O-rings above the piston is the head of air and below of the piston are connected to the water line. When the shockwaves moves through, it compresses with the air inside of the water hammer arrestor, stopping that shock.

If appliance warranty was not enough, without a pressure limiting valve you may not be covered by your insurance company. If an appliance or fixture fails as a result of high water pressure you may not be covered by insurance.

While the Plumbing Code of Australia and the Australian Standards require pressure limiting valves, so do many manufactures of appliances and fixtures. Many manufactures of taps, showers, hot water systems and washing machines, just to name a few, set a maximum inlet water pressure. Water pressure which exceeds their maximum voids their warranty.
