Protect Your Plumbing With a Properly Functioning PRV

March 14, 2019

Protect Your Plumbing With a Properly Functioning PRVA pressure reducing valve, or PRV, is a relatively small but amazingly effective part that can affect virtually your entire home. This important plumbing valve is designed to regulate your home’s water supply at the point where it enters the house from the local utility. Having a properly functioning pressure reducing valve can help reduce your monthly bills, increase the longevity of your water-consuming appliances, and increase the lifespan of your home’s complete plumbing system.

What Is a PRV?

A PRV reduces the higher pressure of the city water supply as it leaves the city main piping and enters your home. The city’s main water supply is typically set at a pressure that’s best for most efficiently pushing water throughout the city, however, those pressures may be higher than what’s most best for your home. Thus, a pressure reducing may be employed to reduce household pressures to more appropriate levels. If your home has one, the PRV can be found near the location where the city water piping enters your home, such as somewhere in the basement or crawlspace.

Why You Might Need a PRV

Not every home comes with a PRV. According to the Uniform Plumbing Code (UPC), which is the primary guide for plumbers and building departments in the Denver-Boulder area, as well as around the country, a new home or a remodeled house is not required to have a PRV if the incoming water pressure is less than 80 pounds per square inch, or psi. In many cases around our region, municipal water systems cannot officially document such high regular pressures to justify requiring PRVs. Regardless, local code continues to move in the direction of requiring them in some new homes.

Know, though, that your home and your appliances may still gain significant benefit from the addition of a PRV. If your home’s water pressure is in the 60 to 80 psi range, that can still place unnecessary strain on your home’s pipes, appliances and budget. If your home already has a PRV, it is a good idea to have it inspected regularly, as mineral deposits can accumulate and corrode or impede the function of the PRV, over time. Water pressure around the home should also be checked at the same time.

How Can Your Home Benefit From a PRV?

Having a properly functioning, adjustable PRV can offer many benefits to your home. It can help you use less water, since the flow rate under reduced pressures will be lower at the faucets and showers; the typical user will consume less water as a result. This means that a PRV can save you money on your water bills, through the reduced amount of water coming out of your faucet or showerhead and straight down the drain. And if you’d like a little less or a little more water at the tap, PRVs can easily accommodate those desires while still saving you money on water consumption.

In addition, the automatic water valves in appliances such as your dishwasher, washing machine, refrigerator water dispenser and ice maker – and the seals in your faucet and shower nobs and levers – will all last longer due to less strain at a reduced water pressure. Lastly, with a PRV, the copper pipes and fittings in your home plumbing will also tend to have a longer lifespan, as well, due to the reduced corrosion rate present at a lower household pressure.
