Ah, my bad. I could have sworn in a previous post you said a 5 in a 4.
I need to replace my original. Cash was in short supply back then so I used a 4 inch PVC wrapped in Ply foil and slid that inside a six inch PVC, worked great for a lot of years but the last few winters in a few spots I've had snow melting. Was going to pull the four inch and the insulation out and slide some in from Z supply. I don't figure I'd have much luck trying to shove a 5 inch tile thru a 6 inch pipe. Already tried with just ten feet and it's doable, don't think a 110' feet will be.
