glue for light niche conduict- electrical or plumming glue??

Apr 26, 2008
What glue should I use for the conduict on the light niche. I know the light niche and conduict will hold water and should be pressure tested. Should I primer and use the electrical glue or use regular pvc plumming glue? Thanks!

I use regular purple primer and pvc glue for PVC conduit. I'm not quite sure how you'll pressure test the conduit though unless the light niche has a fitting on the inside that you can plug. I used PVC glue on the male PVC threads that screw into the back of the niche.

I'm not positive, but I think the PVC glue they sell in the electrical section is just a re-badged version of regular PVC glue.
