Air compressor leaking down

[fred d]

I have a 60 gallon compressor that I like to keep full at all times.

Recently I tried to upgrade to a 80 gallon tank but ended up not being Able to work out because of the way it mounted

Now that I have put it back like it was, I have a leak. I have tried spraying windex at the connections to find the leak but have been unsuccessful

Any suggestions to help find the leak?

I have a valve just outside the the tank that i shut off so it is not down stream in a hose or coupler or anything like that


The drop I would consider large. When it shuts off I kill the breaker so it will not re-start. In 24 hours it goes from 125lbs to 20lbs


I did not re-apply Teflon tape to connections

I do not have a valve between the tank and the pump. It is just galvanized piping with a coupler.
I do have a shutoff valve after the tank

I have tried spraying the glass cleaner around all connections at full pressure and have no leaks

Prior to this, the compressor had no leaks. I would leave the power on all the time and it would not turn on for weeks

Since I did not mess with the drain valve I did not check any connections I did not disconnect

HELP

Sounds like the check valve on the top of the tank might be leaking pressure back into the compressor head.. They all will start to leak back eventually.. Easy fix on most units.

Edit.. I jus re-read your post and you say there is not a valve. I have never seen a compressor that does not have a valve somewhere in it and usually it is inside the fitting at the top of the tank.

I'd add some liquid detergent to your Windex and try again...

If you aren't making any soapy bubbles on the outside of the tank, I think it's safe to assume the air is leaking back through the compressor pump.

Windex is a bubble type mixture
But I thnk the dish sore wold be a better choice, the windex was just there.

I will work on it today and see if I can find the problem between church and Super Bowl
