How do I know if my pressure reducing valve is bad?
Not sure how to diagnose and fix or replace a water pressure reducing valve?
In this article, your local plumbing experts explain the symptoms of a bad pressure reducing valve that may need to be replaced.
Here are five symptoms that could indicate that your pressure reducing valve is going bad.
1. Diminishing water pressure.
If your water pressure doesn't seem to be as strong as it once was, or you notice a significant loss of pressure when you use more than one fixture at the same time. Your pressure reducing valve (PRV) may be bad.
2. No water pressure.
If you have no water pressure throughout the house on both the hot and cold, your PRV may be bad. If there is good pressure on the cold and not the hot it may be an issue with the water heater or the fixture itself.
3. Hammering or vibrating noises in your walls.
These noises can be caused by multiple things such as a PRV, expansion tank, quick closing solenoid valves on new appliances, faulty valves with loose washers, toilets fill valves, improperly strapped pipes, etcetera.
Sometimes it can be a combination of these contributing factors. Things to look for that will indicate the PRV is failing. The hammering noise is originating from the PRV, or the noise occurs when you operate different fixtures in the home.
4. A leak in your flower bed or landscaping close to the house could be a leaking PRV.
Most PRV's in Legacy Plumbing's service are located in this area. However, we have also located them under stairs, in garages, pantries, and laundry rooms.
5. High water pressure.
If your faucets, toilets, or appliances need frequent repair. This could be a symptom of high water pressure. Most fixtures are rated for a maximum working pressure of eighty pounds. To fix this could take a simple adjustment or possible replacement of the PRV depending on the age and condition of the valve.
