Default Help Put This Puzzle Together

I need to install a service on a house. The meter will mount to a poured concrete basement wall. I need to run a 2" PVC conduit into a 2" LB, then through the wall. Here's the problem. They put a 2" piece of PVC in the form when they poured the wall. So now that the forms are off, the PVC is flush with the wall on both sides.


How can I connect my 2" to the existing 2" that is flush with the wall? I thought about some kind of reducer just for entrance/exit of the wall but can't come up with anything. I would need to go back to the 2" after it is reduced to get through the wall.

Any ideas?

Chip around it on both sides just enough so you can glue on an LB is all you can do.

Sawzall the existing PVC, slitting it lengthways with a long blade, and pry it out with a beater screwdriver, then beat a new, longer 2" into the hole.

just for kicks, I'd roll up my heater blanket and jam it in there....let it get nice n toasty, then see what happens with a beater or some such. Probably make a giant wobbly mess......but I'd still try it.....on your job

Drive up to Canada and get you some of that Tek-90 stuff big enough for your feeder. Apparently from what I read here , they let you just stuff that Chit just about anyplace.

I'm really tired right now so I could be way off but do the conduit fill rules apply to short nipples?

If not, then use 1 - 1/2" to go through the wall and 2" outside.

Joe is on the right track:

Further, BEVEL the edge of the newly inserted PVC. Later cut it square and true. You want excess PVC to mess with.

Use Pulling Lube to grease the operation.

Use a hefty block of 2x6 or some such as your point of pounding.

If you're lucky enough to have an automotive puller ( Snap-on, type ) you could rig a squeeze push by punching a hole into your 2x6 pushing plate.

Or, you could set wedge anchors to the left and right and then pull against them while pushing in the new PVC.

You can insert/ pound from either direction, of course.

If the fit looks too tight, consider buffing down the new PVC -- just a tad.

1/32" could make a big difference.

Use it as a sleeve for SE cable.

On the outside cut the hub off of an LB. Attach the belly of the LB to the wall so itís hovering over the existing 2 inch pipe going through the wall.

Then just run the SE cable down the pipe, through the LB, through the pipe and into the panel. That is how I do all of my services now a days. Only without the pipe in the wall.

Thanks guys!
I like the "slitting" the conduit idea but the walls are 12" thick and I probably would have to cut from both inside and out.


I'll "mull" these over and come up with something.

@HackWork are you using copper or Al SE cable?

Use the existing sleeve for cable/data and just drill a new hole.
12" of concrete with a decent hammer drill would be completed faster than farting around trying to use/adapt the pipe

The sleeve should drive out without too much drama, a little chipping around the ends may be necessary if the pipe was shorter than the forms inside width. Use a scrap of steel 2" pipe as a drift.

4/0-4/0-2/0 aluminum SEU cable.

I run a piece of 2 inch PVC down to an LB, then just drill a hole through the house and run a piece of SE cable through the pipe in LB and into the house. Itís just a sleeve for protection.

Why bother with the LB? Just mount the meter pan directly over the 2" hole, SE cable through the back. Can leave the existing sleeve as-is.

Iím assuming the hole is down low, too low to mount the meter.

I didn't mention it but I'm using a meter/main. So I would have to use 4/0, 4-wire SER. Won't make much difference as far as the fit in the conduit though.

Yeah, but Iím not sure if that would make the bend in the 2 inch LB.

for that 4 conductor SER ya can fit but the risk of damage is very high and most LB is not deep enough to make a good bend on SER.

ya have to end up use mougal 2 inch LB or oversized the LB like go get a 2.5 or 3 inch LB verison then it can able fit in.
