Thread: Filter leak

    Filter leak

    Hi there,

    I have a cartridge pool filter that has small leaks around the in and out fittings (bulkheads). Over the years the slab the filter sits on has sunk down a few inches so it no longer sits flat on the slab. One side of the filter rests on a rock wall also so it doesn't completely lie flat on the slab. I believe this is what has contributed to movement of the filter housing and possible leak. I attached some pics. Currently I have some rocks placed under the filter temporarily to try and have it on an even surface.

    Any ideas on how to:
    (1) fix the leak? I was going to try teflon tape on the threads to see if that did the trick
    (2) Provide a flat surface for the filter to sit on... I was contemplating using the hardening foam you can get in a can, spraying it up underneath the filter or possibly using a plastic bag as a mold for it so it doesn't stick to the bottom of the filter.

    Any advice appreciated - thanks!

    Welcome to TFP!!

    Leveling the filter was a GREAT idea!!

    Can you post a close-up of the bulkheads? It may be as simple as an o- ring stretched too much from the filter being out of level -- or... it could be cracks in the filter body itself The filter looks 'older' do you know how old it is?

    I'm pretty sure I can get you through this season, even if the filter is cracked

    Thanks, Here's a close up of the bulkhead, red arrow points to the leak. Not sure how old the filter is, I've been here a little over a year and the house is about 9 years old, so I assume the filter is pretty close to that.

    Can you take a side shot of that so we can see how much stress the filter being out of level is putting on it if any.

    Have you tried just tightening that nut?
