Article requiring pvc stubs through concrete slabs to be wrapped with poly

[Sparkfromtex]

Out of the blue our local inspector is requiring all of our pvc conduits that are in contact with concrete to be wrapped. Is this a requirement of the latest code that I have missed?

Nope, not in the NEC.

That is crazy.

I agree with Bob, PVC is designed to be embedded in concrete.

I'd wrap them in newspaper.:angel:

I'd tell the inspector that you don't go by the urban legend code and that you use only the NEC and any formally adopted local requirements.

Everything is better wrapped in bacon.

Agreed.

and a bit of shredded sharp cheddar never hurts either.

I would also inform him that the AHJ he works for also uses the same code and amendments.

Isn't finding a second use for an item recycling?

Got me.:thumbsup:

I'm guessing that this inspector is mixing the plumbing and electrical codes. The plumbing code requires all pipes to be wrapped with foam or similar material where they are encased in concrete or penetrate a concrete slab.

That IS recycling............oops.....someone beat me to it!

We try to sleeve PVC when it comes up through a slab. Most of our projects do not have the site preparation of large projects. (The slab settles.). This is a personal decision, not an NEC requirement.

And floor boxes are stepping stones.

A practice I just recently started doing is to make your stubs end in a coupling about 1/4 inch below the surface of slab. Tape over coupling of course so it doesn't get filled, and then tape a nylon cable tie to the side of the coupling leaving the tail end of the tie sticking 3/4 to 1 inch above the concrete. Concrete finishers go right over it with no problems and when you come back later you have a little flag telling you where your conduit is.

POCO has us wrap plastic (trash Bag) for concrete encased conduits when sweep cgoes up their poles (in the past) now we keep concrete 2' away from pole. But that has nothing to do with your specific inquiry. :?
