I do not have a light cover and not sure what it will do. Is it possible to isolate the light and nitch on a concrete/plaster pool from the water with this device? Would it be useful to determin if a light conduit does or does not leak during bucket test?

Hey Hapster!

That light cover is pretty handy just for what you described.

I also used it for main drain test. If you set it up right, you can see air pulling up around the outside of the main drain pipe when you
use a Leek Peeker in the skimmer.
