Last night our pool light just fell out of the niche. We tried to put it back in but the holes in the niche are corroded. We cannot attach our light to the niche. Our pool 3 1/2 years old in ground pool and was installed by professionals. If the light is not screwed into the niche are we loosing water through the niche. Do we need a wire plug to stop the water from leaking? We are going to contact the company to see what they can do. Our warranty is up but I will see what they can do. We also have a dark brownish/black ring around the niche. Was all this an electrical issue? Any information would be helpful so I know what I am talking about when I call the company. Thank you.
The brown/black ring is likely from a rubber seal that is likely still attached to the metal ring that was around the lamp.
A pool lamp/light should NOT fall out nor should the threads in the wall corrode in only 3.5 years. Someone did a poor job of installation. I’d suggest that you contact the company that built the pool and acknowledge the pool is out of warranty BUT, they should still replace the lamp. I’ve seen pool lamps last 12 to 15 years and more.
The lamp did not fall out due to some electrical problem … it was lousy installation. The lamp itself comes sealed and there should not be water in the lamp container. If there IS water in the container you should NOT TURN THE LAMP ON. Leave it off. However, if it is still sealed and free of water, there is no electrical danger to you. It is likely that new, larger diameter bolts can be used to re-install the lamp, but remember, I cannot see what has happened and I cannot be absolutely correct. The rubber seal that caused the brown/black ring should also be replaced.
It is unlikely that you are losing water through the niche. (note: I don’t know the real term for the receptacle in the wall for the lamp housing, but your choice of words (niche) was a perfect choice.
