Performed plumbing inspection for customer as part of their maintenance agreement. Found a few issues. Customers water pressure has a significant drop when using more than one fixture at the same time. Kitchen basket strainer starting to rust out, and water heater missing expansion tank. Went over with findings with customer. Also advised to customer to not use cleaning products inside toilet tanks due to causing rubber seals to prematurely wear out and cause leaks. Gave customer options and customer opted to go ahead and get heavy duty prv installed. Installed new PRV and set pressure to 75psi. Checked for leaks and no leaks detected. 1 year warranty on prv replacement.
