Do you have rattly, noisy pipes? Do you hear a loud banging sound when you turn your kitchen faucet off? Well, the culprit may be high water pressure. Not only is it loud and annoying to listen to these symptoms, high water pressure can also damage many of your water based appliances.
If you have high water pressure it can be very dangerous for your hot water heater. These fluctuations in pressure can damage the tank irreversibly and cost you upwards of a thousand dollars to replace it. There are multiple ways to mitigate this fluctuation, the first of which being the expansion tank. Essentially this tank is designed to control the expansion of the water inside the tank as it heats up which can prevent excessive changes in the water pressure. Usually these tanks are installed when the water heater is but sometimes tight working conditions may cause a plumber to forego putting this addition on. If you feel you need a thermal expansion tank then contact a local plumber and it shouldn’t be too difficult for them to get one on. The next best thing to mitigate your high water pressure is a PRV on the main water line coming into your house. This valve basically acts as a pressure drop device. Water comes in at a high pressure, leaves at a lower pressure. This device is much more expensive but it can reduce the pressure coming into your house entirely. This way you know no matter what appliance is being ran it doesn’t have a chance to be damaged by high water pressure. If your home was built after 2002 then you most likely already have a PRV in place. PRVs have a lifespan of about 7-10 years depending on the severity of the water pressure problem in your house, so make sure it is still operating correctly.
All in all, checking your water pressure is something every home owner should do in order to ensure that your appliances won’t be damaged unnecessarily. Should, you have a problem with your water pressure either call a plumber or your water provider and they can assist you in rectifying the issue.
