I searched this thread and didn't find any info., so I apologize if I overlooked. We have a 19 yr. old inground pool with a light that was installed with the original installation of pool. It has rarely worked. The light has lain on the deck for about the last 14years. We now have a leak in the pool and are trying to eliminate all problem areas, this being one. We want to totally eliminate the light, how do we go about sealing off that niche and light area, to keep it watertight?? Please help, we are losing half an inch a day. Grasping at all angles!! Thanks so much!!
