Having a problem that I am uncertain of. Factors are:
1. Old galvanized plumbing replaced with copper from meter to house & through out house by a plumbing contractor in July 2013. Everything, except the pressure valve, is still working perfectly.
2. Model 600XL pressure valve failed to reduce pressure so 160# of city water pressure was going through out the house in 2018 (just over 5 years after installed). Way over what the washer, dishwasher, et al were designed for. Fortunately there were no ill effects from this.
3. Replaced the pressure valve with an exact replacement. Did this myself. New pressure valve worked perfectly until Oct 2021 so I purchased a rebuild kit (figured the brass casting should not have gone bad somehow) and installed all the kit parts, greased the rubber with supplied lubricant, reassembled and it worked perfectly after setting to 65#. Note: stainless steel mesh screen in the valve was clean - not a single bit of grit/sand/rust etc. so don't think contamination would have damaged the rubber parts.
4. Two weeks ago the pressure valve started let the pressure bleed up to 160# when no water was being used in the house. When an outlet was opened the water rushed out with high pressure and then reduced to the 65# the regulator was set for and remained at this pressure as long as the outlet was opened. When the outlet was closed the pressure built up to 160# again within 5 minutes.
My question is does anyone have any ideas why this is happening? I'm not a professional by trade but the valve does appear to be well made and am uncertain if I should get another kit or install a new valve. (Or have a different type/make pressure valve installed. If so any recommendations?) Let me know if I've not provided enough information.
Thanking any respondents for their input, Gene
