LOL very close to what I do for a living, actually. Slightly less messy than in the video, pre-saturated, steam expanded and hardened on site, also works as a chimney flue liner.

Adding video to channels (Engineering) - requested by ant.

You work as a proctologist?

So much work and hassle...Wouldn't it be cheaper and faster just to get a new set of replacement pipes? They had to dig it out, cut it out, line it, then put it back in, etc etc. Seems like just replacing with new pipes would be a better process.

This video is for show, normally they would line the tube in place.

Also most useful if the pipe is inside a wall between two expensive apartments or below something you cant dig under. Its for special cases.

Rain pipe and chimney proctologist. We have a camera on a cable.

what's the max length of the liner? seems like it all had to fit inside that pressure vessel which turns it inside-out upon inflation...

Also, their video example showed a tee that was essentially sealed - what do you do for those? or what about elbows?

This is how I lined your mom's pipe.
