Pond Boss Forums AERATION Systems questions Compressor/Diffuser Pressure Question

Russ I sent you a private email.

Heating of the air in the gauge should make the psi be less not more. If you truly are operating at more psi then something is causing greater back pressure. Possibly an air restriction maybe a kinked airline? Remove the diffuser from pond, uncouple it from hose and run compressor, gauge should read zero if there is no air restriction in airline. IN many "normal" cases with the clean pore diffuser out of the water while operating the compressor the gauge should read zero. Clogged diffuser pores will cause some backpressure with diffuser out of water. Real long airlines or small diameter airlines will cause slight backpressure with diffuser out of water.
