Best way to seal light fixture conduit leak in EMPTY pool?

Postby buck16 » Sun 26 Mar, 2017 00:36

Pool is currently drained to below light line. What's the best way to seal that hole in an EMPTY pool? Found a post with full pool. But what's the best way to do in an empty one?

I'm pretty much done with my light fixture. It doesn't work and I was quoted $1600 to dig up old galvanized pipe that's rusted away at dirt level along with a light fixture that's about 25 years old and no longer good. They'd have to dig up my decking to replace old pipe with PVC and do new light and some other electrical work. I've just cut off the old connection and put the light back in place.

I just want to seal the conduit line which clearly is leaking as I had water coming IN the pool today when I had my hose running into my yard where that old pipe was rusted. And I want to seal water from leaking out, obviously.

Help needed ASAP.

Thanks,
Matt

Hi Matt

It all depends on your light fitting construction
If it's fibreglass, metal or plastic then fibreglass would seal it providing you get a good key (break away any old pipe first)
If it's concrete or gunite there are appropiate compounds available.
You would need to make sure water isn't running in when doing it as it won't bond
Once you refill the pressure of the water in the pool will help to keep the join tight

Hi, I guess what I mean is where the hole is -- where the cord goes thru -- in the back of the metal canister for the light fixture, how do I just seal that? It looks like there is a light cord stopper. Maybe that and something else.

Cut it all back, I would just use fibreglass to cover and seal it
Maybe a few coats

Anderson Butyl tape can be packed in the conduit to seal it. I've also seen the conduits shot full of silicone, but the butyl tape is a better option, in my opinion.
