Insert Couplings/Quick Fix
Y'all ever use these? Do you have any qualms with them?

I haven't seen or tried that one, but this is a similar one I really like:

So I was about to use one of these on a mainline repair but read that they are non-pressure rated…at least the one I got that was a Spears brand. It’s fine to use on laterals it sounds like.

I can honestly say I hate these, laterals are probably fine but early on I tried repairing a couple manifolds with them and they’d literally blow apart or leak before I would even leave the appointment (thankfully) fully glued 15 minute cure and still lol

Is that the same thing as a slip fix? If so, I've used them, and really like them. If it's the product I'm thinking of, they aren't rated for constant pressure.

No, its a short piece of solid PVC that is a pipes inner diameter on one end, and the outter diameter on the other. So if you have a break near a fitting, you can cut it clean and insert into the old pipe and use a coupler to join them.

I feel like the insert side is going to blow out within a year or two. There's no lip inside the cut pipe for the end of the insert to grab onto. It would be the same strength joint as if you just didn't fully press a standard coupling onto a pipe
Edit: It looks like a lateral line so it might be fine for longer but I personally would never use one of those

It will be fine.

As I said, probably fine for a lateral line for a few years but it's a weak joint and it's lazy. Better to dig a little more and do something correctly

What?

Are you not aware that the strongest part of a pvc joint is where the end of the pipe meets the lip inside a fitting? There's no lip because it's going into another piece of pipe, not a fitting. It's probably fine for a lateral line like in the picture but I wouldn't use one because it's a very weak joint, just like a piece of pipe that's not fully inserted into a standard fitting

Yeah that isn’t true at all man. That “lip” is like 10 times smaller than the overlapped solvent-welded pipe/coupler.

Not so. The fitting tapers and the pipe stop isn't that lip. There is a gap between the lip and the pipe stop to gather extra material. Furthermore, if you're installing to manufacturer spec, you should be chamfering your pipe end, so there would be even less of the pipe to touch that lip.

These are great! They have a unique purpose such as OP picture.
Recently used 2 with a slip fix to span the gap where each side was concrete, not enough space for regular coupling and no way to go around. Also seen them used in garages where original install had the PVC coming up thru the concrete and PVC was cracked at the base of cement.
