Never would have guessed having to replace a dead pool light would open a can of worms.
All that I was able to find in a sweep elbow for 3/4" and 1" was conduit, which I'm assuming would be ok in this case since it's not in a water pressure situation. But wonder if being
conduit would matter when pulling the cord. If I placed the 3/4" sweep as close as I could to the wall, it does stick out further than the existing elbow, but only by 3/4" or so.
existing vs sweep conduit
backside of wall since we used 45° elbows here, will assume we did the same for an earlier 90° turn. There may or may not be another 90° pair closer to the pool from the original build.
Replacing the pool light cord piping
Pro:
--Future pool light replacement would not require lowering water below niche so that column and then elbow each be unscrewed to pull the cable straight out from the wall.
Cons:
--Replacing light AND cord is a rare occurance. Is it worth the trouble to not have to lower the water?
--If I replace it, it'd be glued with the (old) cable in place, so there'd be a risk of getting glue on the (old) cable.
The replacement seemed more attractive when I thought that delivery of the new pool light would impact when I would lower the water for replacement of the ball valves and how long I'd have to leave the water at the lower level. But now the light is supposed to arrive Friday and I'm not going to start the drain until Sun, so not an issue now.
Really have a hard time with this. Would like to hear from
@jimmythegreek on whether he thinks it would be worthwhile to replace my existing pool light cord piping from the wall (3/4" pvc, 1" threaded elbow, 1" threaded column) with a glued-in 3/4" conduit elbow.
