We wanted to share an important issue that may be affecting many of our homes: high water pressure coming into the community from the street.

 

Recent readings down on King Street and N. Dearing Street are showing water pressure around 90 PSI. The recommended/code limit is 80 PSI.

 

We spoke with Virginia American Water about the situation and were told that the higher pressure is being maintained in order to ensure adequate water pressure throughout the community. With all of the new construction and development taking place around us, it is likely that the system pressure has been increased to help accommodate the additional demand.

 

While that may help maintain pressure throughout the larger system, it can be hard on our 70-year-old homes and plumbing systems.

 

Our homes were built decades ago, and many of the plumbing components and fixtures have been in service for a long time. Consistently high water pressure can put additional stress on those systems and may contribute to:

• Knocking or banging sounds in the pipes
• Increased pressure on your hot water heater
• Added stress on expansion tanks, which can potentially lead to failure or rupture
• Premature wear on faucets, toilets, valves, and other plumbing fixtures
• Leaks or plumbing failures that might otherwise have been avoided

 

What can homeowners do?
One of the best ways to protect your home from excessive water pressure is to have a pressure reducing valve (PRV) installed.

 

A PRV regulates the water pressure entering your home so that your plumbing system isn’t subjected to the full pressure coming from the street. These valves are typically installed inside the home, near the main water shutoff valve.

 

If your home does not already have a pressure reducing valve, we encourage you to research PRVs and consider having one installed by a qualified plumber. It is a relatively simple way to help protect your plumbing, appliances, fixtures, and ultimately your home from unnecessary stress.

 

And because we are all connected as a community, protecting your plumbing can help protect our neighbors as well by reducing the likelihood of leaks, failures, and water damage that can affect adjoining homes.

 

We know that plumbing issues aren’t always top of mind, but this is one of those situations where a little prevention can go a long way — especially in homes that have been standing and serving our community for roughly 70 years.

 

Please consider checking your home’s water pressure and whether you have a pressure reducing valve. If you aren’t sure, a plumber can help determine what your home currently has and whether any adjustments or improvements are appropriate.

 

Thank you for looking out for your home, your neighbors, and the Fairlington Towne community!
