Customer complaint of noise during normal use of fixtures around the house. So while waiting for company to arrive customer adjusted PRV valve down to help reduce the noise. Technician confirmed that the noise had been coming from PRV valve. Customer explained that this had happened in the past and over a period of six years the PRV valve had to be replaced. Being that it was six years from last replacement technician installed a new PRV valve . Tech confirmed that there were no leaks coming from the new PRV valve or meter. Water was restored to the house and outside showed that the house was set to approximately 50 psi (customer supplied WATTs pressure gauge confirmed). Numerous fixtures had been tested sure that there was no longer a noise present coming from the waterlines. Card authorization # 00183P
