So I had to do a repair on a PVC line that was leaking. I had a 2 inch PVC line coming down and needed to join another line to it. I was very short on space, and couldn't work a traditional coupling in there. The fellow at the hardware store suggested a slip or repair coupling. After thinking about it a bit, I went instead with a Fernco and it's worked fine.
I wondered about the repair coupling, though, and I had some extra PVC pipe left over and a couple bucks in my pocket, so the next time I was at Lowes I bought a repair coupling just to try it out on some scrap pipe. I primed the coupling and slid it up one side of the pipe, and then I primed the ends of the pipe I was joining. Then I spread glue all over the ends of the pipe and slid the coupling down so that it was between the two pipes and I gave it a bit of a twist. I pushed the pipes together for about 30 seconds.
After a couple minutes I gave the pipe a tug and a twist to see how things worked On one pipe the coupling and glued on rock hard. The other pipe, though, with a grunt I pulled it right out of the coupling. It didn't get glued in at all!
This is what I was worried about and why I went with the Fernco. To my thinking as you slide the coupling over the pipes you push all the glue out and away from where it is needed. This is what seemed to happen.
Did I do something wrong? The Fernco cost $7 and the repair coupling was $2.10, so there's a difference in cost but not huge. I searched around on YouTube to try to see how other people use the PVC repair couplings and there aren't many videos. The guy at Lowes told me to do it just the way I did it, but that didn't work. Thoughts?
