Mine leaked, dump valve would open when i filled sometimes. Got the new diaphrams and they still sucked. Sold the rear set i had and bought 1/2" SMC's. I sill have to swap the front valves to smc's because those are messed up also.
My friend has a set of GC's and he has no probs at all.
Im just not going to take the chance of getting valves that are messed up.
