Happens in Texas, though. That's why they like slip x slip valves
A threaded joint is just another possible leak and I've seen many leak, not mine but they can leak. I like glue in valves but leave room for replacement.
I see threaded valves as supplying a measure of stress relief in poly-pipe systems.
Poly mains are for pikers.
Poly and PVC in the hands of children:
I wonder what size of jumbo box was over that mess?
I would think the poly wire sleeves were more of a hassle than protection.
I believe there were three standards; the poly sleeve was most assuredly a hassle because we cut through it many times while rebuilding the botched system.
These are some of the reasons I asked my question. Here we trench pvc mostly. I do see some Poly for laterals but for the most part it's all PVC.
I personally like installing slipxslip valves but have started using threaded a bit more.
I can see a properly laid out manifold having some advantages to repairing and replacing valves ( if the installer left room ).
Nor I .... at least one I built .... but that doesn't mean I don't allow for easy replacement either.
Well I gotta say I don't think any threaded valve is as good as a solvent weld. I rarely reuse a pvc threaded valve after its been used once before. The pvc misforms when you thread something into it. I don't trust them not to crack on the second go round.
In addition the male adapter is the weakest fitting made. I suppose you could use nipples though.
