the seals in your regulator are bad.take a full tank of co2,hook the regulator up like it was ready 2 run.instead of pluging it into a timer plug it right into the wall.listen and feel for any leaks.there really easy 2 take apart and repair.if i remeber right u want to buy polyurethane o rings if u need to.go to a co2 shop and ask them what kind rings they.those are the ones u want.
disrupt86 Reviewed by disrupt86 on . co2 regulator leak I have a 25 or 30lb co2 tank (not sure which) with an Optimum Growth regulator. I've had them for over a year and have had problems with them every once in a while. 2 weeks ago I got my tank filled and the gauge on the reg. said it had 1000 psi. Everything was going great until I woke up this morning and the entire tank was empty. This is not the first time this has happened. I haven't made any adjustments to it since setting it the day after the tank was filled and somehow it emptied 1000psi Rating: 5
