I live on a 2 acre lake. We put in an aeration system 5 years ago that has been running 24/7 since.

The system consists of two diffuser locations with 4 diffusers in each location. First location is about 50 yards from the compressor, the other is about 100 years from the compressor.

The diffusers closest to the compressor seem to be putting out about the same volume as when new. The one farthest away from the compressor is definitely not putting out as much volume.

I'm assuming that the compressor is not pumping out as much air as when new.

Any suggestions as to what can be done maintenance or repair wise? (unfortunately the documentation that came with the system cannot be found).

Much obliged,

Allan
