Replacement diaphragms are available and easy to change the pumps giving years of service.

Diaphragm life can be extended by ensuring diffusers are not in water deeper than recommended maximum depth of the air pumps. Use weighted 3/8" airline between the pond pump and the diffusers for runs less than 50'. If you are running airline more than 50' we recommend using a 1/2" or 5/8" airline between the pump and diffusers will further ensure trouble-free and extended pump life.
