What are the symptoms of a PRV that is no longer working properly?
A sudden loss of, or a gradual reduction in water pressure within the home for no apparent reason. A banging or high pitched whistling sound coming from the pipes usually when the water is being turned off. PRVs may also fail in the open position providing higher than desired pressures. Typically there is no indication this may have occurred other than noticeably higher pressure at the faucet or toilets that continue to run after the bowl is filled.
