Had to call a pro to fix our radon mitigation system after the alarm went off. Turns out the fan motor burned out, letting pressure drop and radon levels climb back up. The technician replaced the fan, resealed the sub-slab suction pipes, and reinstalled the manometer to monitor vacuum. Now the gauge shows steady negative pressure again.
