Good catch - I ended up disassembling my entire PVC setup as I used the water stuff and the wire didn't fit easily; too much concern over breaking the wires.
I'm not certain the concern here, so please elaborate. Yes, it's for future wiring (though right now it simply works great as an "intercom" down to the basement when we're pulling wire). It's a 3" pipe, and it's completely straight and vertical, except for the 45 deg you see there. I'm planning on putting a heavy nylon rope down it and then capping it.
If I should ever have to pull wire, it will be like we do now, where she pushes from below and I just take up the slack above....so even if there are any rough edges in there, we aren't going to pull hard across those. (in other words, I think we're too far gone to replace this thing now, so I'm trying to convince you it will be ok after all.
