Customer is having problems with pressure and water temperature. The master bathroom shower is not working as it should. It is very hard to temper the water. It takes a longer time, than usual, to get hot water. Once it gets hot, it doesn’t cool down very quickly. The cartridge, for the Moen shower, is not functioning as it should, the house is less than 2 years old. While searching for a cause for the cause of the failed cartridge, I found static house pressure to be 114 psi. There is a pressure reducing valve on the main line but it has absolutely failed. The pressure far exceeds code maximum. The pressure reducing valve needs to be replaced to protect the home’s plumbing system from future problems and increase the longevity of the fixtures. The cartridge for the master shower should also be replaced because that has also failed, due to the high pressure. **House pressure has to be less than 80 psi** - I cleaned and rebuilt the master bath shower valve and tested for leaks and prop
