Ridgid pressure switch works some of the time...
I have a rigid tri stack, 5 gallon, 150 psi.
I can detach the 1/2 gallon tank and motor from the other two tanks w/a built in hose coupler.
When detached, the 1/2 gallon tanks fills normally to a 150 psi. and shuts off automatically.
when hooked up to the other two tanks, it fills up all the tanks to 150 psi, but doesn't shut off and does NOT blow the pressure release valve, it keeps running.
makes me think it is releasing the pressure some where but not sure where or if it is the pressure switch. Any ideas?
