We found the plumbing system lacked a proper access point to perform air testing and locate additional burst pipes or failure points. We recommended installing a boiler drain to allow accurate testing, improve diagnostics, and ensure the system’s safety and reliability. During the installation attempt, we discovered the existing pressure-reducing valve was aged, no longer operating reliably, and showing signs of leaking. Replacement of the valve was recommended to maintain proper water pressure and protect the plumbing system from potential damage. The pressure-reducing valve was replaced, and a new quarter-turn drain valve was installed to provide future access for pressure testing and system drainage. While shutting off the water supply, a minor drip was observed at the water meter; the retaining nut was tightened and the leak subsided. Prior to air testing, a known burst section of 1/2” copper water line was identified, which prevented proper testing of the system. We recommended r
