Diaphragm Replacement Kit for Clearstream CS103ET & CS103ET6 Septic Air Pumps

This air pump repair kit fits Clearstream models CS103ET and CS103ET6. The kit includes the necessary components for replacing the diaphragms on your pump. The diaphragms normally need to be replaced every 4 to 6 years depending on the application. When the diaphragms fail, the pump will shut off and your alarm should sound. If the air pump is over 10 years old, we would recommend replacing the air pump.

This kit includes 2 diaphragms with mounting blocks, 2 heads with air valves, a replacement air filter, and a replacement gaskets.
