Pressure Regulator Valve

What is a Pressure Regulator Valve and What Does it Do?

A water pressure regulator valve does exactly what it sounds like. It regulates the pressure of the water coming into your house. It affects everything from your shower pressure to your water heater, so it is something you will want to be sure to get right.

Who Is Responsible For The Pressure Regulator Valve?

As you know, your water comes into the house from your municipal provider, but once it gets to your household meter, it becomes your responsibility. Pipes and systems, like irrigation systems and water pressure regulators, are installed after the meter, so they are the homeowner’s responsibility. You are responsible for the install and maintenance of your home’s regulator valve. 

What Goes Wrong With These Systems?

An existing pressure regulator can fail and increase your water pressure or, even more commonly, it can gain mineral buildup over time that reduces the water pressure inside your home. This is especially true in areas of the Valley where the municipal water is very hard. One word of caution, if your pressure is irregular or has changed, don’t automatically assume that your regulator valve failed. It may just need adjustment. 

Who Needs a Water Pressure Regulator Valve & How Should they be Set?

Not every home has one, but if your water pressure exceeds 80 psi, it is required to have one, and it is definitely preferred in areas where the pressure to your home varies or when it is consistently too low or too high. Most pressure regulator valves have 50 psi as the preset pressure limit. People tend to find that this psi feels too low for comfort, so you can contact your plumber to measure your valve settings and get it how you like it (safely!). 

How Long Should a Regulator Last?

The quality of these valves varies, so while some pressure regulator valves can last 20 years, a typical lifespan is 7-12 years. A qualified plumber can help you determine if your valve is having issues. We don’t recommend you attempt to adjust the pressure on your own, unless you are highly skilled in this area, because too much pressure on the home can damage faucets and lines.

How Do You Know If Your Home Has a Water Pressure Regulator Valve?

If your plumbing has a water pressure regulator valve, you will find it near the water main. It is roughly bell-shaped with an adjustment screw and a lock nut that sits below the screw. Your plumber will be able to identify it and test its functionality to advise you on its status. 

How Much Does it Cost to Install a Water Pressure Regulator Valve?

It costs between $250 and $400 to install a water pressure regulator valve for both materials and installation.
