    Intex drain plug problem

    I'm having a leaking problem with one of the drain plugs on my Intex pool. The plug on the inside started leaking a bit two years ago. I solved the problem by sealing the outside cap with some teflon tape. That stopped it from leaking for two seasons, but now the cap is cracked and it's letting the leak through. It's not gushing out, it's just a slow trickle, but I still need to fix it somehow. I tried using a standard PVC cap, but of course nothing with Intex is standard and the threads are different, so it's not sealing. I found what appears to be a replacement cap on Intex's website, but I was wondering if I should try sealing the inside plug shut instead. I don't use the drain plugs to drain it, I use a pump, so I don't care if they're permanently sealed. I don't think that outside cap is meant to hold water, I think it's just there to cover up the treads that are used to attach the garden hose adapter. Is this a good idea or a bad idea? If it's a good idea, what should I use to seal it shut? PVC glue? DAP contact cement? Silicone? Something else?

    Edit-I forgot to mention that I wouldn't have to drain the whole pool. I just started filling it, so I would only have to drain an inch or two to get it below the plug.

    Re: Intex drain plug problem

    you can use this, fill the inside of the broken cap and screw back on, this stuff is permanent so only use it if you never want it off again
    once screwed on you can use the rest to coat the outside also and if you have 2 you can fill the other one...

    This is meant for fiberglass and wood, not sure how vinyl would react to it.

    that is mostly what it is used for but here is a graph of everything it sticks to and seals they do not specify vinyl but I have used it and it worked great

    *Overlap shear strength values are approximate. Adhesion tests should always be performed on the specific substrates to be used in application.

    **Resins used in fiber reinforced plastics often vary. To ensure strong bond, adhesion tests should always be performed on the specific substrates used in application.
