The Dangers of Having High Water Pressure in Your Plumbing System

High water pressure in showerOrdinary plumbing systems can safely function with up to 80 psi (pounds per square inch) of water pressure, but often the incoming water supply is 100 psi or more. It is extremely important to have a PRV (pressure reducing valve) installed so that the pressure going into your home can be controlled.

If the PRV isn’t operating properly, the water pressure circulating inside changes. Water pressure also increases when water is heated in your water heater.
If this extra volume isn’t released, it can cause problems in your plumbing system, such as a leak in the water heater’s pressure release valve. This can be avoided by having a thermal expansion tank installed to hold the added volume of water.
High water pressure can damage your faucets, tub, shower valves and toilets. If the pressure seems higher than normal, check the PRV to make sure it is working properly. Replacing it in time will save you a lot of time and money.
A simple way to find out the exact pressure is to get a water pressure gauge. A normal reading should be 40-80 psi, and this can be checked by placing the gauge on a faucet outside. You can also attach it to your washing machine faucet to check the incoming pressure and ensure that the appliance doesn’t get damaged by high pressures.
Ideally, water pressure shouldn’t be less than 50 psi either. If you don’t have a water pressure gauge, another easy way to check the water pressure is the conventional multi-flow method. Turn on the faucets in your bathroom, kitchen, washing machine, dishwasher etc. This will give you an idea of what the pressure is like.
You can call in a plumber to have a high water pressure issue fixed. They will install a pressure reducer to control the pressure going into your home, or fix the pressure-reducing valve if it’s broken.
