Dewalt D55141 slowly releases pressure after pump up

The compressor will still push the pressure up but when it shuts off with no tools attached you can hear a hiss. It is not the safety valve. It will come back on and shut off during use.


However if I shut it off when pressurized and do not drain it it will leak out completely within a few minutes.

Any suggestions of what that might be?

Empty the tank. Remove, clean and reinstall the tank check valve.

Turn on compressor. Is the problem gone?
