Customer called us out for a mainline blockage in the master bathroom grouping. I tested the bathroom and it started backing up free a few minutes. I recommended running a cable machine through to clear the blockage. Customer agreed. Customers PRV tested at over 100psi and leaking , the hose bib on the side of the house was leaking and the water heater was 20 years old. I scheduled a service plumber to come take care of the PRV. I removed the toilet and ran the cable machine down 8 times successfully clearing the blockage. I tested and cleaned the area. I then plugged the flange for a sewer supervisor coming out on Friday.
