We knew there was at least one leak coming from the drain return pipe but when we got it dug up we could see that there was a leak coming from the light (last year the glass and frame came loose and just fell off--see photo 2). The metal housing for the light had rusted through in a couple of places (see yellow circles in photo 1).
Itís very difficult working on this because the pool is like a bowl with a small ledge around it but it appears that some of the areas where the light screwed into are compromised and I donít think weíd be able to put the glass and frame back in (also, Iím afraid the same thing might happen--it would just fall off again eventually).
We don't want a working light, we want to stop the leak.
Can we use pool epoxy putty on the holes and then coat the metal with something? Thereís still a lot of moisture/water coming up through those holes because the ground is so wet. Or maybe cover it with some type of plate? Any suggestions would be really appreciated! We really want to be able to do this ourselves because of the cost factor in hiring a pool company.
Some history on the pool: Itís 50 years old with a concrete bottom and gunnite/metal(?) sides that were coated with fiberglass about 25 years ago. The pool light hasnít worked for about 25 years. There was some updating done to the pool about 5 years ago and the man working on it wasnít able to fix the light but put it back in place.
