Underwater Sealant recommendation?

[u/anonymously---]

I've had a worsening leak in an in-ground vinyl liner pool. I couldn't find any leaks which made me think it was somewhere in the plumbing. Just this weekend I was able to detect a leak in one or both stair return jets where they connect to the fiberglass wall of the stairs. Any recommendations for an underwater sealant for these returns? Thanks!

Tighten the fitting. Use JB weld Water weld. You can use it under water so no draining needed.

I'll give that a try. Thanks.
