Re: [GSAS-Member] CO2 Question
Check valves are designed to stop flow one direction when they see a specific
back pressure. If that back pressure is not met they can weep fluid in the
reverse flow direction.

Ah that must be what happened to me. Because I turned off my CO2 at night,
water would creep back sometimes. The only issue is, is that not what check
vavles are for, to stop water?
