For this job, I replaced the relief valve on the water heater. After I install the park, I noticed there was a shut off valve leaking above the water heater. After talking to the customer about replacing that valve, he gave me the OK to have that done. After replacing the shut off valve for the upstairs, turning the water back on, I checked for leaks, and found none. After bleeding the waterlines to the kitchen and bathrooms sink, I did not find any other issues with this system. I did notice there was two other valves had corrosion and I talked to the customer about replacing those valves when they start leaking. He said, when the wood burner goes out, He would like for us to do a couple things on the waterline. As of right now, he does not want those valves replace.
