Regulator shows increasing water pressure
We installed a Watts Adjustable 263A-LF Regulator, set at 50 PSI, between the hose and the RV water intake. All seemed fine, pressure stayed constant according to the gauge on the regulator.
Then we got a water softener and connected the regulator after the softener: water bib - softener - pressure regulator - RV.
Checked regulator a few days later and pressure was well above 50 PSI, it went as high as 100 according to the gauge at one time. Lowering the pressure by way of adjusting the gauge did no good, pressure stayed high.
Contacted the seller who thought the hot water heater had lost its "air bubble" and asked that I drain and refill it, which I did. Also back flushed and disassembled and cleaned regulator. That did not resolve the issue- the pressure still creeped up to unacceptable levels on the gauge.
Moved gauge to up stream from softener and it holds steady at 50 PSI. Water bib - regulator - softener - RV.
During all of this the pressure from the faucets inside the RV did not change appreciably.
Seller says this is not regulator problem.
But I never heard that a water softener would increase water pressure.
Any like experiences or suggestions as to the cause?
