under sink cartridge won't stop leaking
We installed new filters in 2 cartridges under the kitchen sink. It is the Omni Heavy Duty II filter system and we installed 1 GAC1-ss and 1 CB3 (on the CB3 we had to remove the bottom small gasket, to make it fit!). We installed 2 new O rings with proper lube. The cartridge on one side leaks, we've pushed the air release button, reset the cartridge and tried everything. Still leaks pretty good - drip drip drip! What else can we try? Why do you think we can't control the leak?
Thank you for any advice! ~susie~
