UF Conduit Drainage
All the instructions for installing UF wiring underground in PVC conduit say to glue joints together. Dude I work with has suggested that it might be better to leave joints open since the conduit is basically there to protect the wire from compression damage, and the open joints would allow the inevitable water gathering in the conduit to drain out. Anyone have any experience or thoughts on the matter?

Water may enter conduit, but you should glue the joints to eliminate the possibility of it happening. Any "hole" you put in it will also allow water to enter it, so that theory is shot in the foot. You should be using THWN wires in the conduit anyway, which are water resistant, and made for that application. I would not attempt a long run of UF cable in conduit unless you oversize the conduit a little. It can be unwieldy. But by the same token, UF cable doesn't care if it gets wet.

Thanks for the tip. In thinking through the scenario, I've also realized the open joints would be the perfect place for kinks to develop under compression. I'll be sure to glue the joints.

Tell us about your project and we can tell you how to do it correctly. It sounds like you are relying on friends with only partial knowledge and some of the BS You Tube Videos on how to do things. If you want reliable info about how to wire buy a book such as Wiring Simplified available at Home Depot and other building supply retailers and at on line book sellers such as Amazon.
