If your Clearstream CS103EL has recently stopped working, you should consider rebuilding it before purchasing a new one. Buying a brand new model is extremely expensive. Typically you can rebuild your Clearstream CS103EL for a fraction of the cost. However, not every air pump can be rebuilt. If your aerator has a red dust built up inside of it, that means that your coils are rusting and you will need to purchase a replacement air pump.
Similarly, if your air pump has already been rebuilt once, it may be time to buy a new air pump. You can find replacement air pumps at Wholesale Septic Supply.
If you have determined your Clearstream CS103EL can be rebuilt, then the Clearstream CS103EL Air Pump Rebuild Kit has everything you need. The kit comes with two replacement diaphragms. It also has 2 mounting blocks for the diaphragm. The kit also comes with a brand new air filter and a safety pin.
You (the customer) are responsible for making sure you are following all applicable laws and regulations in your area before replacing your septic air pump yourself.
