A faulty pressure-reducing valve can be a challenge. If you notice water leaking from underneath, it may be a sign of a problem. Are you unsure about how to troubleshoot and repair or replace a malfunctioning water pressure-reducing valve?
In this article, local plumbing professionals provide information about the signs of a faulty pressure-reducing valve that may require replacement.
What is a PRV?
A Pressure Reducing Valve (PRV) is a device that safeguards your home’s plumbing system from excessive water pressure. To prevent damage, local building codes specify that household water pressure should fall within a range of 40-80 pounds per square inch (psi). When the water supply to your home exceeds this limit, the main water line remains within a safe and acceptable range.
While PRVs are designed to be impervious to wear and tear. Their rubber components and springs are prone to degradation, and the presence of particulate matter in the water can cause them to become clogged. As a result, PRVs often deteriorate gradually, and the onset of problems may be subtle, especially if your water usage is moderate.
If pressure-reducing valves (PRVs) become worn, they may lead to various unusual water pressure problems in your entire household. It’s crucial to understand that these symptoms typically manifest simultaneously in different areas of the house when a defective PRV is to blame. Should you encounter any of these problems with just one specific fixture, it’s unlikely that the PRV is the root cause.
1 Low or Fluctuating Water Pressure
Low water pressure or inconsistent water pressure may indicate a faulty pressure reducing valve. You may notice weaker water pressure than usual or a noticeable decrease in pressure when using multiple fixtures simultaneously. This issue might become apparent when there is a higher for water, such as when guests are visiting and using multiple tubs and showers at the same time.
2 No Water Pressure
Occasionally, PRV problems can arise suddenly, rather than developing gradually over time. If you in your home is non-existent, affecting both hot and cold water supplies, it’s possible that your PRV has failed. Be sure to test both hot and cold water lines to is normal but the hot water pressure is low, the issue may be related to the water heater or a specific fixture, rather than the PRV.
3 Hammering or Vibrating Noises
Persistent thudding or steady whirring sounds emanating from the walls when operating various Valves (PRV).
To the previously mentioned causes, various other factors can also contribute to these noises, including a malfunctioning expansion tank, rapid closure of solenoid valves in newly installed appliances, defective vacuum breakers, valves with worn or loose components, deteriorated toilet fill valves, and pipes that are not properly secured.
At times, the sound may result from these influencing elements. To further validate that the PRV is the source of the sound, move to its position and listen closely. The sound should be distinctly louder near the PRV.
4 A Leak in your Flower Bed
Chrome Air Conditioning Plumbing serves the northern part of the Dallas Metroplex. In this area, the majority of Pressure Reducing Valves (PRVs) are typically situated on the main water line as it emerges under the home’s perimeter in the front flower bed.
In newer homes, constructed after 2010, the location of these components is often more varied. You may find them concealed behind a garage wall panel that houses plumbing lines. Additionally, they can be situated in wall cavities beneath staircases, within closet spaces,
In some cases, the valve may rupture, resulting in soggy or waterlogged area in your garden or flower a sign that this has occurred.
5 High Water Pressure
High water pressure may cause your faucets, toilets, or appliances to require frequent repairs. The standard maximum working pressure for most fixtures is 80 psi, and if your water pressure consistently exceeds this limit, it can lead to faster wear and breakage of parts.
Adjusting the pressure at the PRV to decrease it may in certain cases. Yet, if the PRV has been in use for several years, this could pose a significant risk. Trying to make adjustments could result in the PRV malfunctioning completely or developing leaks.
