Call for hot water issue and pressure in shower. Arrived and spoke with Mr. Ashim. He has several problems with showers upstairs. Master showers both have poor water pressure when hot water is called for. His daughter’s shower has poor water pressure on both hot and cold. Hot water takes a long time to be delivered to the master shower as well. I inspected the plumbing system and found the following: Two 11-12 year old Bradford white atmospheric draft gas water heaters, ran in a series. A recirculating pump had been installed with a crossover tees in daughter's bathroom, under furthest vanity. Shower head and mount in this bathroom full of sediment and debris. I cleaned as much as possible and flow appears to be fully restored. No significant amount of sediment found on cold only lines such as toilet tanks. Pressure regulating valve is less than a year old, with the previous valve being from 2018, as stated by homeowner and prior plumber. PVC main from meter to home, 5en transitions
