under sink cartridge won't stop leaking

[susie-stanton]

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~

Hi Susie,

It sounds like this may be an installation issue. Omni actually has a technical support team that could probably help you troubleshoot the leaking. They can be reach at 800-934-6664.

Thanks, Roxanne - I think we have it solved... but will definitely keep the number handy; we have 2 more sinks we use your filters at, and am sure this is going to come up again <grin>

Have a good weekend!

Before you can stop a leak, you have to find its source. That can be tricky. Water that escapes your pipes can travel a long way before it drops onto your cabinet's floor.

Here's how a drip detective tracks the source of a leak: Fill both bowls of the sink with lukewarm water, not cold. (Cold water can cause beads of condensation to form on the pipes, making it impossible to find the leak.) Then get under the sink with a trouble light. Dry off all the pipes and examine the seals around the basket strainers (see photo, p. 94). If you don't see any droplets forming, remove both sink stoppers and watch for telltale dribbles. Joints are the most likely source of leaks, but old metal pipes can develop pinhole leaks anywhere, especially in the trap. If you cant find any leaks in the drain system, check the water supply lines that serve the faucet. Finally, check for "splash leaks," spots where water seeps under the sink rim or faucet base. To find these leaks, use a rag to dribble water around the faucet and sink rim, then get underneath and look for drips.

Else filters needs to be replaced with a new one. If you are not familiar with this type of job. Call someone that does, a friend or a plumber.
