Pressure Valves help control the excessive water pressure provided by the city to ensure a safe level for residential use. Typically installed on the main water line, these valves are commonly placed in the front garden area or concealed behind an access panel within an interior wall.
A malfunctioning PRV can lead to a range of problems, including irregular water pressure, unusual sounds, and leaks. This is a frequent issue in our region, and PRVs often begin to show signs of failure after 8-15 years of service. We offer a straightforward, flat-rate pricing structure for PRV repairs, and our technicians are equipped with the necessary tools and parts to complete the job quickly and efficiently.

What is a PRV?
A PRV, or pressure in a home. Just as the human body requires a stable blood’s plumbing system relies on a balanced water pressure to prevent damage and ensure efficient operation. Ideally, the water pressure should fall within 80 pounds per square inch (PSI), as specified by plumbing codes. This range allows plumbing fixtures, supply lines, and water-dependent appliances to perform as intended. However, when water pressure exceeds this range, it can lead to premature wear and tear on the plumbing system, increasing the risk of leaks and floods over time.
Numerous towns located in the Northern DFW region experience elevated water pressure levels typically made to meet the. If your residence was following the adjustment in water pressure, it likely necessitated the installation of a Pressure pressure-reducing valve (PRV). For homes built before this requirement, it is advisable to assess the current water pressure and consider installing a PRV if needed.
The valve installed on the main water line at a home city’s high pressure to a suitable level for household use. Its location can vary, such as in the front flower bed for older homes or behind an access panel inside the house or garage.
Upon initial installation, these valves function as intended, safeguarding your home’s plumbing system. However, over time, these valves may deteriorate, leading to various typical signs of water flow and pressure issues.
Symptoms of a Failing PRV
At times, a faulty PRV can lead to a drop in pressure and water flow across the whole system. This issue may worsen gradually and go unnoticed. If you experience inadequate water pressure from various faucets in your residence, a failing PRV could be the culprit. Another common indicator of a failing PRV is when you have sufficient pressure when using one faucet but experience a significant decrease in pressure when another faucet is turned on.
Noises
When various faucets are turned on, pressure-reducing valves may begin to produce unusual sounds. This can manifest a consistent humming, squealing, or knocking noise that occurs each time you use different faucets in the house.
High Pressure
Excessive water pressure can lead to the malfunction of the PRV, causing high-pressure water to enter residences. While not as immediately noticeable as low water pressure, this elevated pressure can contribute to the deterioration of household plumbing. Another symptom may be the occurrence of a water hammer, characterized by a banging sound within walls when a faucet is swiftly closed, which is particularly prevalent during the operation of a washing machine.
Leaking
PRVs may also malfunction due to leaks. When positioned in the front garden, a wet, mush area may develop around the valve. Check for any accumulated water inside the valve box, which is typically covered by a green lid in a rectangular or circular shape. The box could be hidden underground and difficult to pinpoint.
Replacing a PRV
If you’re experiencing problems that seem similar to these, don’t hesitate to reach out to us. Our team can visit your location to conduct diagnostic tests to confirm whether a Pressure Reducing Valve (PRV) is present and if it’s nearing the end of its lifespan. If replacement is necessary, we can take care of it for you.
When the valve box is situated in a flower bed, we undertake a comprehensive overhaul of the water line to ensure the pressure-reducing valve (PRV) and main shut-off valve are easily accessible and maintainable. This involves excavating the existing box, removing outdated fittings, and repositioning the line to a more convenient depth. We then installed a new PRV and a ball valve, followed by a new valve box. To prevent future mud accumulation, we fill the base of the box with pea gravel. Although this process is labor-intensive, it’s the correct way to install the box from the outset.
When a Pressure Red Valve (PRV) is installed in a system, a corresponding expansion tank water heater. For more information on expansion tanks, visit our dedicated service page. If a suitable expansion tank is already in place, no further modifications will be needed. However, if an expansion tank is missing or the existing one is faulty, a new one will be installed at the water heater as part.
Once the landscaping to its original condition, leaving no visible signs of our presence. Upon completion, you’ll be left with a fully functional and easily maintainable PRV, as well as a new stainless steel ball valve that allows for effortless shut-off of your home’s water supply without the need for specialized tools.
