The feed from the power pole to my house lands in my driveway near where the breaker panel is. It's where the driveway meets the garage completely surrounded by concrete. When the house was built (before I bought it) they added a second electrical PVC next to the feed from the power pole, assuming to allow future access to the area without busting up concrete. Problem is, I don't know where the pipe is stubbed out at. Anyone have any ideas on how to feed something down the pipe to detect where it stubs out. Or generally how to find where the pipe is stubbed out the concrete under ground?

Metal fish tape and a metal detector?

Conduit, so you have conduit going into the ground but you don't know where it comes out?

There's no wire in the conduit?

You could put a garden hose to it if there's no wires and that will blow you a hole.

Most of the time those are not exactly planned by a rocket science and just come out right there.

I would imagine the fish tape would appear less on a metal detector than the rebar in the concrete. Wherever it comes out of the concrete, I'm guessing the pipe is clogged with dirt. Worth a try if the pipe is stubbed out far enough away from the concrete though.

Yes you described my challenge in fewer words than I did. Ha. No wire in the conduit either. It is nice someone planned for future use for once.

And yes it is a conduit. I used to work in a commercial electrical field, and that required the galvanized metal conduit and my brain correlates "conduit" to metal conduit which I know is inaccurate. Hard to break my brain's habit though.

Simple and not complicated is what I'm hoping for. Is electrical PVC the same fittings as plumbing PVC? Seems like I've ran into an issue where electrical was different. But it's been awhile.

Either way I'll see if I can get an air tight seal on it and see where the water comes from.

I dig down to confirm the direction the conduit goes. Assuming it is straight, it might give you a more specific place to look. Might terminate in side the garage or shed...

The problem is it goes down straight into concrete and the closest place it could come out is 30' away in any number of directions.

My guess is it either follows the other conduit all the way to the pole or it stops right outside the concrete.

And unless someone had special directions during construction, that pipe probably goes straight to the pole. So just stand at your meter and look at the pole and more than likely thats how its run.

Some fittings are the same and some arent. Plumbing 90s arent electrical 90s. In general, plumbing pvc is white and electrical is gray.

Call for a one call and have them come out and mark your electrical utility line to the transformer. If they were smart enough to run a spare, hopefully they were smart enough to run them right next to each other.

A fish tape and a pipe locator could do it. Most plumbers would have both of those. I also agree with speck…99% chance it follows the route of your existing power service.

I’d also say it was more likely a mistake or there was a change order, then they were planning ahead. It’s certainly possible. But more likely the above. It’s also possible it’s for adding a panel or outlet like a shed, hot tub, etc.

Here's a crazy idea that might work - get a Tile or similar tracking device, attach to the end of a long fish tape. That will give you a location +/- the working distance of the Tile.

Plus Electrical 90s are “sweeps”, which turn corners gradually so you can pull wire thru them

google dowsing rods. A couple of pieces of wire, makes no difference what kind, about 2 feet long. Bend about 6 inches of each piece at 90 degrees. hold i piece in each hand loosely and walk in the area. The rods will twist toward one another over ANY pipe in the ground. Empty electrical conduits, ferrous or non ferrous, makes no difference, Test it over a known pipe in the ground....I have used it thousands of times to find empty pipes, water lines, drain fileds, junction boxes. It works. Takes no special skill or any sort of magic....anyone can do it. Its been used for centuries to find water but it will find any sort of void underground. It flat works. I know many will claim otherwise but I will guarantee you I can find your conduit with 2 pieces of #12 solid copper no matter how deep it is or what kind of pipe it is. If its there it will work,.
