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.

With over 60 years of plumbing experience, you can rest assured that we know a thing or two about adjusting a pressure-reducing valve. We’ll work quickly and efficiently to ensure yours is set at your desired water pressure, keeping your pipes safe all year round.

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 top part of the regulator should have the adjustment screw and the lock nut. The former raises and lowers the water pressure, but before you can adjust it, the lock nut must be loosened first. Turn the wrench in a counter-clockwise direction to loosen the nut. Be careful not to turn it too far, however.

Now, let’s look at how you can adjust a water pressure regulator yourself—having one won’t do much good if it isn’t set properly!

A water pressure regulator is a specialized type of valve designed to ensure the flow coming in from your municipal water supply is manageable for your pipes.

Next, you need to find the water pressure regulator. This is a bell-shaped device that’s close to the main water supply and sits on top of the pipe.

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.

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.’

With that in mind, keep reading to learn more about them and the steps involved in adjusting a pressure-reducing valve. Let’s get into it!

Now, position the wrench over the top nut of the adjustment screw and turn it accordingly. Counterclockwise turns will decrease the pressure, while clockwise turns will increase the pressure. The water pressure gauge will indicate changes in PSI.

Water pressure regulators—a.k.a. pressure reducing valves—play a quintessential role in residential plumbing systems. As the name implies, they control the force with which the water flows through your pipe—thus making for a strong or weak flow.

Below is an example of water pressure before and after a pressure limiting valve was installed. This particular series is by one of our Plumbers Kurt.

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.

However, if the water pressure in your home becomes too high or too low, you may need to adjust them manually. It’s also a smart idea to do this before the end of winter in preparation for the heavy rain that comes with the spring season.

While adjusting a pressure-reducing valve can be easy, there are always risks associated with DIY handiwork—especially when it comes to plumbing. So, to avoid costly mishaps, consider calling a professional plumber from PlumbWize.

Step one is assessing your home’s current water pressure, as you should have an idea of where it stands before making adjustments. The easiest way to do this is by attaching a pressure gauge to any hose spigot and then observing the reading.

We hear you. Who doesn’t like a shower massage. You do not need to worry. A pressure limiting valve set at the correct kPa will still enable you to have great shower pressure.

Once you have the desired pressure, tighten the lock nut back into its original position by doing the reverse of what you did before. This will ensure it stays set!
