Connections
The air outlet is internally threaded for use with the included barb adapter, but we recommend using the provided rubber elbow when connecting 3/8" tubing. Larger tubing can be connected directly to the smooth outer surface of the air outlet. The 14mm outlet is suitable for 1/2" tubing, while the 18mm outlet can accommodate 5/8" or 3/4" tubing. Additional adapters are required to use 1/2" tubing with the 18mm outlet. For models utilizing brass connections for septic pump alarms, the brass measures 4mm in diameter.

2 Year Warranty
This warranty does not include the diaphragm kits, which are a replaceable, wearable part (typically replaced every 12-18 months). Warranties are at the discretion of the manufacturer as to whether the damage is due to misuse or to defect.
