Burying Conduit


Shouldn't be. As long as it stays together.
I might have used a bit more glue on that joint.

I actually had quite a bit of cement on the elbow and inside the bell. I think the large radius of the elbow combined with the depth of the bell contributed to the gap. (A curved piece mating with a straight piece) I suspect that the end of the elbow made full contact somewhere inside the bell.

Some inspectors here insist on seeing excess squeezed out of the joint - that way it is visually confirmed that it's fully glued. I'm not sure that's an enforceable requirement, but it is good practice. It's impossible to use too much.

I put a light coat in the bell and two fairly liberal coats on the pipe/elbows. Think I'll be alright or should I relay some new pipe?

Whats the opinion on running a second conduit for tv/internet cable in the trench next to the one carrying the power? Interference concerns? Should there be a minimum separation between the two conduits?

if you're really worried about it, put the first 8-10" of fill in then add the LV conduit, but i wouldnt worry.

I agree on both counts.

Just curious... but you guys HAVE seen this issue in the field, right? Where a large radius sweep leaves a gap in the bell because of the bell depth?

I was talking to an electrician earlier today who stated that he's never seen this problem. He asked about the sweep and when I explained that both ends have spigots, he said I should either be using a sweep with a belled end or making the connection to the conduit with a standard coupler. A gap wouldn't be left that way because the connection wouldn't be as deep as the bell on the conduit? If he's right, whats the point of being sold a sweep with two spigot ends? lol...

Where did you obtain such a sweep elbow? None of the ones I have ever bought have bells on the ends ....

That's just it... my sweeps do NOT have bells. So therefore, you either have to insert the end into a coupling or into the bell on the end of a length of conduit, which leaves the gap. The electrician was the one who said I needed sweeps with bells on them.

So when YOU install large radius sweeps, how do you connect it to the straight conduit? If you fit it with the bell of the conduit, have you noticed the gap?

Generally, I don't install sweeps into bell ends, for the same reason.

So you use regular couplers? Regardless of sweep size?

All the prebent 90's I have used have had a short straight section on each end so you don't have that problem. Did you cut the end of the 90 off?
