I'm having issues with my air meter. When I hooked up the air line it ran constantly and was leaking out of many locations. I got most of the leaks stopped and I cleaned the filter on the main valve. The only change that came from that is that now the bell dings constantly along with it running. I'm getting air shots to the hose and the only leak that I have is through the boxed in space that leads to the tube that is cut off behind the main valve. I figured it doesn't matter if its leaking before it makes its way out of the tube cause it goes out into the open anyway but from what I understand air shouldn't be coming out there. Is this a check valve issue? Any assistance would be appreciated.
