Talked to owner today as I was picking up Radon CRM (22.3 pCi/L, maybe that is causing it, said with tongue-in-cheek). PEX is 10 years old. Took another closeup picture of a fitting behind the well pressure tank.. Owner runs dehumidifier, setting two feet away, all summer. Could someone not have put as much pressure on the rings as is required? Can the clamping tool get out of calibration?
