A full diagnostic assessment was performed to determine the source of the leak. Prior to inspection, approximately 1/2" of standing water was extracted from the crawl space; water had been pooling around the leak location and dripping through the insulation near the ductwork. All accessible water was removed and a fan was used to assist with drying; due to the size of the affected area, some residual moisture remained, but the majority was eliminated. Two sections of 1/2" trailer PEX were found to be leaking due to deterioration and rodent-damaged fittings. The damaged Tee fitting and affected pipe sections were cut out and replaced with new hot and cold PEX lines, transitioning to the existing polybutylene piping using appropriate adapters. The water system was turned back on and tested, confirming no leaks were present at the repair points. The homeowner was advised that the water-damaged insulation should be replaced and properly insulated to help protect the pipework.
