The Blue Diamond ETA Series Air Pumps with Alarm are widely known for their use in the septic industry, but they are also suitable for any application where timely notification of air pump failure is critical. Whether for your aquarium, pond, or septic system, these pumps ensure you are promptly alerted in case of malfunction.Compact, weatherproof cast aluminum alloy body

Note: Blue Diamond ET series aerators are intended for use with relatively low pressure. It is recommended that the tubing does not exceed 130 feet in length, and the diffusers should only be used in water depths of up to 7 feet. This ensures optimal performance and longevity of the aerators.

Alarm System
The alarm system features a 3-position switch. Set the switch to "test" to activate the alarm and light for testing purposes. Always ensure the alarm is functioning correctly before installation. After installation, you can set the switch to "alarm" for a flashing light and alarm sound, or "mute" for a flashing light without the alarm sound, depending on your preference.

The air outlet is internally threaded for use with the included barb adapter. However, 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 all models utilizing brass for connection to a septic pump alarm, the brass component measures 4mm.

2 Year Warranty
This warranty excludes the diaphragm kits, as they are replaceable parts that typically need to be replaced every 12-18 months due to wear. The manufacturer will determine whether damages are caused by misuse or defect when assessing warranty claims.
