12v Pond Air Compressor Pump - low pressure

[saxon11]

Hi - I have a 60W 12v air compressor for my 1/4 acre pond. It has worked great for past year, now isn't putting out enough pressure to make it through the hose. It does run though. Does anyone know what general maintainence I could do on this to get it running well again?

Did you purchase the pump new? If so, here is my guess: The pump was made in 2016. Even if it was never used, the rubber components will have certainly hardened just sitting on the shelf for 7 1/2 years.
If you purchased it used, my guess is the diaphragm is worn and needs replacement. Another possibility is a worn or stuck check valve. In either case, it might be cheaper and advisable (especially if you acquired it used) to replace the pump.

That is what I figured, easier to just buy a new one. Thank you
