here, everyone is either all pvc, or pvc mainline and poly laterals. some are using what i think is pex only, which i am only slightly familiar with.
pvc is better imo, due to our very rocky soils. like i said, from a repair standpoint from years of doing it, i could see what is the most durable in our soils and conditions. poly is pretty nice, easy to work with really, but have seen it punctured so many times I could not justify using it myself.
all is fair in love and grass!
Man, it smells like sheet, do you smell that!!
