Here’s an idea, leave it to the real plumbers and use actual pipe fittings instead of rigging your plumbing for failures later on and having to fix it again!The idea is great, and the video performance is beyond the norm. Well done.Place a coupling on one end, make a short stub with coupling number two, lay alongside cut longer pipe end to meet the second coupling center, assemble and glue, if there is not enough room to do this it's time to dig or go to other side of wall and make it. A leak can cost way way more than just doing it right.
