Understanding Pressure-Reducing Valves: FAQs for Homeowners in Austin, Texas

Pressure-reducing valves are an important component of a home plumbing system, as they help maintain optimal water pressure levels throughout the rest of the system. Without a properly functioning PRV, a home's plumbing system can become prone to leaks, inadequate flow, and other problems. However, despite their importance, PRVs can be confusing for Austin, Texas homeowners who are not fully acquainted with them. To clear up any uncertainties, we have compiled a list of the most frequently asked questions (FAQs) when it comes to understanding PRVs.

What is a Pressure-Reducing Valve?

A pressure-reducing valve is a plumbing component designed to control the amount of pressure in the pipes flowing into your home. It is typically installed in a main water line that supplies water to the house and consists of two tightly sealed discs that are made to open and close in order to maintain the desired pressure level. This helps maintain the flow of water to fixtures like sinks, showers, and toilets while also preventing overly high pressure levels from causing damage.

Why is a Pressure-Reducing Valve Needed?

Municipal water supplies typically operate at fairly high pressures, with pressures up to 70 psi being common in many cities across the US. If those pressures were to be applied to a home's plumbing system, it could cause fixtures to burst, pipes to corrode, and other costly damage. A PRV allows you to set the pressure level of the water coming into the home to a safe and optimal level.

Where Should a Pressure-Reducing Valve be Installed?

A PRV should be installed as close to the point-of-entry of the water as possible. This will allow for the most accurate readings and help ensure that the intended pressure levels are maintained throughout the rest of the system. If the PRV is installed too far from the point-of-entry, then it may not be able to effectively reduce the water pressure.

How Do I Know if My Pressure-Reducing Valve Needs to be Replaced?

There are a few signs that indicate a PRV may need to be replaced:

Water pressure is too high: If the water pressure in your home is too high, then the PRV may be starting to fail and should be inspected by a professional.

Leaks around the valve: If you see any water leaking around the PRV, it means the seals are probably failing and it needs to be replaced.

Strange noises: Strange noises or "banging" coming from the PRV can indicate it needs to be replaced.
