In response to Re: Water Heater PRV and acceptable PSI rating
: 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.

no it is not standard for a company to replace your prv when they replace your water heater. some companies do check water pressure and suggest installing or replacing the prv if pressure is to high. The brand WATTS prv in 3/4 inch 25aub comes preset at 55lbs. and should be repaired or replaced if pressure exceeds 80.lbs..if your plumber did not replace the prv you may want to call him to do it though it is not standard to include this in the price of the water heater so expect to be charged for it.
