Interior conduit
I am running THHN for new circuits inside wall cavities. I will be using PVC conduit. I do not plan on having any pull boxes.
Is it required that the PVC be glued on interior conduit that will not be exposed?

Have you looked into using ENT (smurf tube)? It would be a lot easier to run than PVC, and the only joints will be at boxes. You can buy it in 100-250 ft rolls, I think. Chances are if they allow PVC, they will allow ENT.

I will check into smurf tube. i was also thinking of EMT. This way I will not have pull boxes as I can pull the wire as I go. I can use connectors and hide the enire run behind drywall.
Any thoughts from anyone?

Hi, I guess as long as it's in a wall, I'd glue it too. If it was exposed, I wouldn't. Just like drain pipe, as long as there's no pressure in it, you don't have to glue it, that way you can take it apart later on if you have to without any problems.

Having run wires both in EMT while assembling it as well as afterwards, I have to say, it's almost always easier to assemble the conduit assembly, run a fish tape through, then pull the wires through. I usually leave a pull string in the conduit for future use.
Some people have recommended tying the pull string to a plastic grocery bag and using a shop vac to pull it through for long conduit runs. Haven't tried it yet, but I'm dying to.
I think you'll have an easier time pulling the wires through after it's all assembled vice doing it as you go.

Are you kidding? Drain pipe always needs to be glued. There is pressure in it as soon as there's a clog and the drainstack fills up. Not to mention the sewer gas seeping through the unsealed joints.

Pulling wires as you assemble the conduit is a bad idea. You still need pull boxes at least every 360 degrees, regardless of when you're pulling in the wire, and those boxes must be accessible for the life of the structure. Do you conduit work first and pull in the wire on rough-in before the wall is closed up.

To add to that. If you ever need access to the drainage pipe, its not that hard to cut it and put a coupling where you cut it.
