3 Signs Your Backflow Relief Valve Should Be Replaced

Backflow valves are a vital part of any plumbing and fire suppression system. They must be tested annually and replaced or repaired by a certified professional when needed. Replacing the valve before it fails can help avoid a major plumbing disaster. Knowing what to look for can help you determine when you need replacement parts or a replacement backflow preventer. Here are three signs your backflow preventer needs attention. If you notice any of these signs, call your local backfow testing or repair company. 

Water Leaking from the Valve

If you see water leaking coming out of the valve, there could be a decrease in supply pressure or there is water hammer. If you notice any water leaks coming from the valve, it could indicate that one of the check valves is not drip tight. In a static state, a leaking valve could mean the first check is compromised. In a backpressure condition, a leak can indicate that the second check is compromised. A compromised check can be due to a worn seal that needs to be replaced, or debris stuck in the check valve. Some water leaks aren't noticeable, but if you start seeing rust and corrosion around the backflow relief valve, that's a sign that there is a small leak. 

Frequent Cycling

If you notice that your backflow relief valve is cycling on and off more frequently than usual, it could be a sign that your backflow relief valve should be replaced. When a backflow valve starts to fail, it will often start cycling on and off in an attempt to keep the water pressure in check. 

If you notice that your water pressure is spiking, it could be because the backflow valve is no longer working properly. When the backflow valve can’t release the pressure buildup, the water pressure in your system can spike. This is a clear indication that you need to replace your backflow relief valve.

The Valve Is No Longer Closing Properly

Valves that don't close properly may allow contaminated water to flow back into your property's clean water supply. Preventing backflow is one of the main functions of a backflow valve.
