Omega 75 cu. ft. bleed valve leak

I had the same issue. Order yourself a set of o-rings for the pushbutton and have them on standby and just replace as needed. Quick fix, just don't loose the little split ring holding the push button in place.

RMF... thanks! but which one is it? i had a set of orings but did not have the exact one. but thankfully it was close enough and seems to be working.
