Your aerator should last you many years. They just need a little upkeep every season or two to keep them going! 

These pond aerator rebuild kits include:

• Replacement diffusers (or diffuser membranes if applicable) and
• Diaphragms
• A brief instructional handout with a QR code link to our more comprehensive  instructions on our blog. 

 The photos on the left are for your reference only. These rebuild kits only contain the above items, not the aeration systems themselves.
