Thread: Quick fix to Hayward Filter leak?

    Quick fix to Hayward Filter leak?

    I took my Hayward DE-6000 apart for cleaning, reassembled, and now have a small drip where the top PVC enters the filter from the multipart valve. This happened last the pool guy cleaned it, and I thought he fixed it, although he may have done a quick kludge.

    I would also like to do a quick fix now, and fix it right next time I disassemble it. Any chance of stopping the leak from the outside? Can I pop the filter top off, put some type of sealant around the pipe, without back washing? What sealant?

    Almost none. Even if you can get it dry enough, any temp sealant will quickly let go when the leak is from the inside.

    In the manufacturing process PVC fittings will sometimes have a seam contains extra material that runs perpendicular to the threads. I had to take a file and smooth this seam out and my leak stopped. The file needs to be in the shape of a triangle so as to not damage the threads.

    Is there a sealant that is safe to use on the inside of the filter?
    Something that would hold until next time I disassemble everything (and risk having to replace more PVC outside the filter).

    I have used clear silicone (one part acetoxy rtv type) in the past for hairline cracks on a sand filter flange. I applied it to the inside. You need to have a roughened surface for it to "grab" to. It may work for a short time but it won't last forever. Also be aware that cracks in a filter are under pressure and could be the focus for catastrophic failure at anytime.

    Thank you.

    I don't think I have a crack in the body. I think the leak is due to an o-ring or the PVC connection.

    I sort of misunderstood the location of your leak. Can you not just drain the filter, check the o-ring, and use pipe dope or teflon tape to remake that threaded joint?

    Yes, but I was trying to put if off. Now I just want to make sure I have everything ahead of time before I disassemble.
