Regulating Water Pressure - Andy's Pipe Dream Plumbing

Why is it important to regulate water pressure?

Code regulations state that water pressure in a household must be maintained at 80 psi.

Reason being that all appliances that require water in the household operate at that specific psi or lower. Anything above 80 psi can cause severe damage to the plumbing in a household.
As plumbers, we come into your house and commonly find issues such as dripping faucets, running toilet, appliance issues and leaky water pipes. These issues are a direct result of high pressure. When looking into a toilet or faucet, if you notice the parts have prematurely worn then the most likely explanation is high water pressure. If you have an appliance that makes unusual or loud noises when filling (icemaker, dishwasher, laundry machine, etc.) often vibrations from high water pressure can cause parts to wear out quickly. When it comes to water pipe, added pressure causes turbulence, erosion and even can cause holes to wear within the pipe.

So how do we resolve this issue?

It’s a simple fix, install a pressure reducing valve. This particular model of valve is a WATTS ¾ inch AUB, which is our most common install. There are many shapes and sized for varying applications, but the overall purpose is the same – to lower pressure below the level of 80 psi.

When beginning the installation process, we find a space in the water system specifically where the water will enter. This will regulate the water pressure throughout an entire home.

This concludes our discussion of pressure regulation and pressure reducing valves. An important note: when installing a pressure reducing valve, often a new problem is created known as a closed system.
