Upon inspection, we found the circulator gaskets leaking, the bolts rusted, and the boiler drain leaking. We replaced the gaskets and bolts on all three circulators and installed a new boiler drain to restore safe, reliable operation and prevent future leaks. The existing thermal expansion tank and safety pressure relief valve were outdated and not functioning properly. Both were replaced to ensure safe, dependable operation of the heating system and to prevent potential water damage or overpressure issues. The new relief valve was positioned to stand vertically and piped to the floor in accordance with code requirements. After completing all repairs, we purged the heating system, turned all ball valves back on, and ran all zones to verify proper operation. The system was thoroughly checked for leaks — none were present.
