I was called to a home to replace a pressure relief valve on a natural gas Burnham hot water boiler with an indirect water heater. I arrived at the home and found the water leaking from the boiler. I removed the old valve and replaced it with a new one. I also checked the pressure relief valve and found that it was working properly. After completing the repair, I tested the boiler to ensure that it was working correctly. The homeowner was very happy with the work I performed and thanked me for my help.
