In response to Re: Water Heater PRV and acceptable PSI rating
The main ramification is that the relief valve should be operating frequently since it is supposed to open at 150 psi. The more immediate problem is that your faucet connections are not designed for that pressure and you may have them breaking and flooding the house. Replace and/or adjust the PRV as soon as possible.

: I had a new gas hot water heater installed in September, 1999. However, they did not replace the Pressure Reducer Valve (PRV). The current standing pressure no my hw tank is 150psi. What are the ramifications of having that much pressure hitting the tank? Apparently, the new thermal tank and PRV are bad.
