Replaced a pressure reducing valve (PRV) to regulate water pressure in the home's plumbing system. First, shut off the main water supply and drained the system to prevent leaks. Removed the old, malfunctioning PRV and inspected the surrounding pipes for any signs of wear or damage. Installed a new PRV, ensuring it was securely fitted and properly aligned. Adjusted the valve to the optimal pressure setting for the home. Restored the water supply and tested the system to confirm stable and correct water pressure.
