Hello- I'm a pool repairman for the past 18 years. I've eliminated many corroded and leaking lights with an aluminum plate riveted over the niche.
Im looking for other ideas that guys have used. I'm considering a 1/4" plexi glass disk the same diameter of the niche gasket with holes drilled and counter sunk like the light ring and screwed in place to fill the void.
Think that will withstand the pressure?
Any other ideas?
