Drain Plug stripped

[Philo]

My neighbor has a filter pump that has drain plug in the bottom of the housing. It has a slow drip. When I try to tighten it, it gets sort of snug then breaks free and needs another full turn, breaks free and over and over again.

I'm sure he'll never used the drain plug. I'm thinking to get some "Crazy Glue" gel, put it on the threads and pray.

What do you think?

Does it have an o-ring? If not, try putting one on before super gluing it...

You can generally buy new plugs if it's the plug that is stripped.

The o-ring is there.

Whether or not I used it, I'd be pretty angry if my neighbor who was watching my pool glued anything shut.

Get another one and double then up. The threads are "popping" past the last thread, hence what you are describing. By doubling up the o-rings, it will snug up before the plug "breaks free". Also get some Magic Lube. Like this:

or if you have a Leslie's by you, the exact same product repackaged with their name on it:

You could also wrap with teflon tape. I think it's often not recommended on plastic, but the pool company appears to have used it when servicing the previous owner with no bad effects. It may tighten up the threads just enough....

It seems like the threads are "fine grade" and because they are plastic hey collapse on themselves.

If the threads on the plug are stripped, replace the plug. If it's on the pump, you could fill the hole with PC-11 Marine epoxy. Then drill and re-tap the hole.

I'd start with the easiest, and cheapest solution. Try the Teflon tape. And even though the o-ring is still in place, check it for cracks or dry rot. A new o-ring and some tape may do the trick...if not, your only out a few cents and a little time.
