    Any tips on replacing O-ring on DE filter?

    Hi All,
    My FNS Plus has sprung a slight weep at the center o-ring. I bought a replacement oring (which is giant btw). Any tips on replacing it or just install and tighten?
    Thanks,
    Joe

    Just make sure the grooves are all cleaned out and use plenty of pool lube. It's pretty straight-forward.

    cruz=- please make sure that you double the o-ring over on itself and don't pull overly hard when applying the lube - you don't want to stretch the o-ring!
