Going into a PVC pipe to dig out concrete

We have no idea where the PVC ends up outside. So what we need to do is be able to send into the PVC some type of concrete drill attached to a long hose to get to the concrete and drill to the outside of our house. Is that possible?

Ayuh,... Ya got a Tape Measure don'tcha,..??

Measure, inside, 'n outside, til ya figure out where it's Supposed to daylight...

Assemble a length of iron pipe, abit longer than the pvc, slide it to the end, 'n pound on the end stickin' outa the pvc, against whatever's there...
The sounds made should help Id, just what material is there....
With somebody Outdoors, the exact spot should be able to be found, by beatin' on the sounding pipe...

the ends of the vent pipes must have fallen short of the exterior wall,the plumber cut them off at the concrete form with them later needing to be extended (upward/outward??) and out and to the exterior of the exterior wall. the concrete guys covered them up in the slab, though if the plumber made it to the form with the pipe then the end of the pipe is right near the edge of the concrete. is the slab close to level with the grade of the land outside or is it a really thick slab with the plans to just hook a vent pipe cover onto the pipe where it extends out of the slab? if someone knows the spot for the final vent exit point it would make it much easier to pin point.

Ok. Great idea so we did the measure tape thing so far for the dryer vent, but since hubby had to go to work we didn't get farther than that. It sounds like the iron pipe might just work. I will try to let u know tomorrow sometime. Thanks

Yes, I do believe you are correct. I am hoping it's really close to the concrete, so we won't have troubles trying to get thru it.

So I have to wonder if the PVC was ever intended to be used as exhaust conduit. In any case, assuming you have conventional wood stud walls, why don't you run conventional dryer and stove hood venting through the walls? Much easier than attempting to drill through a solid concrete wall, which can certainly be done, but is a lot of work for a large diameter pipe.

I did some research on what u and another person said about PVC pipe not used for our purpose and found u to be correct. This ticks me off because the plumber should have known this and used correct pipes. He does commercial plumbing, so not sure if he does residential. My hubby knew him from a security site he was working on where they were laying commercial plumbing. unfortunately for us this was not the only screw up by the pluming layers.

so someone on a post mentioned using the PVC as a route for our pipes. Would that really be a possibility?
