    Been away for a few days and come back to a porly compressor

    I leave it on all the time as use it regularly.

    My neighbour has been popping in while I was away and she switched it off as it was running all the time.

    On inspection I noticed one of the couplings had come off the pipe. I reconnected it and then discovered the pipe had split so I cut that bit out.

    Fired up the compressor and let it build up pressure which it does ok. It then cuts out, as normal, once up to pressure however there is a leak coming from inside the pressure control box. Took the top off, after switching it off, and pushed down on the large spring inside which stops the leak but as soon as i let go it starts leaking again. As the pressure drops the leaking slowly stops until it reaches 90 psi.

    It normally builds pressure and once up to pressure cuts off and is silent

    So is it fixable or do I need a new pressure switch?

    If I need a new one can I just buy one from ebay?

    It is not the pressure switch. There is supposed to be no pressure when the pump is off.

    There will be a check valve where the air enters the tank. That is probably dirty or the plunger is deformed. They are a standard part. Take it apart to see if it has something in it.
