Water leaking from PVC plumbing near the solar feed or return lines at the equipment pad.

Safety first: Turn off the pump and relieve system pressure. Do not work on pressurized plumbing.

• Locate exact leak: Dry the area and observe where water first appears when the pump is running to identify the failing joint or fitting.
• Support piping: Add pipe supports or straps to reduce stress and vibration on the leaking joint.
• Cut out and replace: Use a PVC cutter to remove the cracked fitting and a short section of pipe. Clean and dry the mating surfaces, then glue in new fittings and pipe using appropriate PVC primer and cement.
• Allow cure time: Let the cement cure per manufacturer instructions before repressurizing the system.
• Test for leaks: Restart the pump and inspect the repaired area for any seepage.
