i did the test to find a leak by turning on the tank without connecting the ball lock and turning it off to see if it would hold steady at 30 psi. it didn't, i figured maybe it was the regulator equalizing, but it went down pretty far, to 10 or so.

i have a new plastic washer on the tank connection and sprayed down all the connections with soapy water... nothing.

the only thing i didn't have tightened during the first test was the nut that tightens up against the body of the regulator on the pressure set screw... would any co2 be able to leak from that?

gracias.

well, i tightened the nut and no luck. it went from 30 down to 10 overnight... can't find this leak anywhere. the regulator is a little older, got it from a buddy and it has some thread seal compound on all threaded connections... i tried to take it apart for reassembly but those things won't budge... if i CAN get them off, should i use yellow gas line thread tape or thread seal compound to redo all the connections?

dunk the whole thing in your bathtub - that leak's got to be somewhere.

just splash some soapy water on any connections, you should see your leak bubbling instantly.

Was the gas connected to the keg when you lost pressure? If so, I assume you tested the keg for leaks?

I dunk the grey quick disconnects in a pitcher of water, sometimes they leak ever so slightly.

i may try the grey disconnects in water...

i tried spraying the connections liberally with soapy water to no avail.

no, the kegs were not connected when i saw the drop in pressure.

oddly, after setting it to serving pressure tonight, it seems to be holding steady at 15 psi. i set it at 10 and after being in the fridge a while, it upped to 15. i disconnected it, turned off the tank and it's been holding the 15 ever since... i'll check it in the morn and see if i need to further investigate it.

thanks for the replies.

ok, it's dropped down again to 8 overnight, i thought it might hold at 15, but no dice... i'll be doing some dunk tests in the bathtub tonight. i will let y'all know what i discover...

is there any worry about the pressure gauge being submerged?

I will place a bet that its a intermittent leak in the pressure relief valve - I've had one of those before.
