Can I Bend PVC Conduit With Wires Inside?


I have a conduit right in the way of a drain I have to install, it's already wired and everything is installed.

Can I safely hit it with a heat gun to bend it a few inches out of the way?

I have seen an electrician do it during a pool install, he bent it more than a little bit with a heat gun. Did it like it was no big deal, I know it was not real hot because less than a minute later he touched it with his hand.

No.

But you're going to do it anyway.

Ironically, this is under a pool deck.

I hope so, I just did the same thing a couple weeks ago.
Same deal, was the electric line running out to the pool. Homeowner assured me the line wouldn't interfere with that corner post hole, I was sceptical so we hand dug that one. 18" down found the line running smack dab through the center of the hole lol.
Dug back either side a couple feet, heated it up a bit, and nicely bent it about 3" just out of the way of the post.

It will bend nicer with one of those heating pads made exactly for that purpose.

PVC bends at 170 to 220. THHN usually has a limit of 194 (90C). So you need to keep the temps on the lower range so you don't damage the insulation.

I'd be too afraid to destroy the conduit. Heating and bending PVC is usually done with a bending spring inside the conduit to prevent it from deforming. Even if you successfully bend without destroying conduit, you might want to meg out the wires before and after to verify you didn't melt the insulation. If you must do it this way, have a hose or bucket of water on hand to cool it down soon as you finish the bend.

Do you ever run PVC surface mount in garages? Or is it “junky” looking vs EMT
