Engineer shows on his design drawings for an underground run of Robroy conduit a plumbing metal TEE fitting with the branch pointed down and extending with more conduit into a pocket of stone.

I'm thinking to comment back to him to show a buried pullbox where he needs to have these underground conduits drain.

Comments?
 
The engineer must be from rural Indiana


The handy men out there. They only carry plumbing pipe and fittings. Because plumbing pipe holds wires but electrical conduit will not hold water.:) It saves on driving 40 miles one way to the box store.

He forgot the check valve?

Just kidding. I'm not sure why that wouldn't just be an electrical "T". I believe code also allows drilling a small hole in a fitting for a drain.

But if its somewhere you could use a pull box, your idea is as good as any.
 
I too thought about an electrical tee fitting but I stopped that line of thought after thinking that a tee would be a condulet with a cover. Is there such a product that is a tee fitting without a cover? Can a condulet be buried?
 
Why not take a one foot piece of conduit and drill some holes on the bottom side of the conduit and place that section in the low point with the drainage stone.

If you want to be helpful and proactive, my suggestion is to explain first off that a TEE fitting must be accessible. Such as a in ground pull box. Second, as stated, the fittings have to be listed for electrical, not plumbing, and third, any conduit extending from the "third" leg has to terminate in a fitting as electrical and fourth, one doesn't want that fitting to be open to bugs and rodents. And starting with Rob Roy, this is not a low end patch job obviously. So the solution, is in ground box, T fitting oriented where the cover can be removed. And a Crouse Hinds or equal stainless steel breather/drain fitting to provide termination on the drain leg. It would seem that just dumping out in the ground box would be fine, but if he want to extend it first then a coupling with the breather installed as a plug, should suffice.
