Replacing a light--detail

[fre1102]

I'm replacing my in-wall light. I guess basically my question is if I need to keep the exposed wires on the end dry--i.e. do I need to drain the pool below the light niche, or do I need to seal up the 'open' end of the wire jacket, or can that get wet/flooded while I install the light and pull the wire through the flooded conduit?

Any other tips, too. Right now my plan is to cut the wire on the old fixture and use it as a pull string for the new wire, which I thought I'd twist together then wrap with about two dozen wraps of electrical tape. So it'd get wet, but I'm not sure how to avoid that without draining the pool.

You don't need to drain the pool.

Attach a cord/twine/rope/fish tape to the wire at the junction box. If they installed the conduit correctly, fish tape would be best. Then pull the light out of the pool, pulling the cord/twine/rope/fish tape through the conduit.

Attach the new light wire to the fish tape and pull it back through to the junction box.

Dry it off well and hook it back up.
