WM Nitro
Anyone else had this happen?
I never use these valves for installs but the existing front yard already had them installed. Figured I'd try to keep the valves all the same. My guy glued a piece of sch 40 into the valve and heard a "crack". He pulled the pipe back out and this is what we found. I put a piece of pipe in there to hold the crack open for the picture. This is one of two valves that cracked. I returned them and installed my go to valves instead.

I've had that happen on glue fittings before. The only thing I can think that could have caused it (other than a defective fitting) was dull cutters created a lip which exerted too much pressure on the fitting when inserted. At least it cracked immediately and not a couple of days after you pulled off the job.

I bevel every single end, but this is for manifold construction and 24/7 pressurization plus water hammer.
One other thing bothers me about that valve. It looks like they just re-used the mold of the older threaded-end valve, and modified it for slip connections. But maybe that isn't a problem if the molding is done properly. The threaded-end valves are made of a different (friendlier) plastic than the slip valves.

It's a freakin Weathermatic! That explains it right there. You could at least use a Rain Bird DV. Sure there is a 95% chance that it won't ever turn off but at least the body won't crack!

Something about slip valves bothers me.
