I am not the best guy to answer this question, but I have seen that it was not replied to so here goes.
What kind of pressure are you putting on the main line?
Are you using compression fittings or glue/Primer?

I am a hard pipe guy for mainline. I don't see the benefit of a poly mainline, but I live in Texas.

I guess your trenches are still open.

How many feet does your mainline run?

Poly Pipes blowing at connections

Hi!
Installing a sprinkler system for the first time. Think everything is done 'by the book' but when water is turned on to test, I kept having the pipes blow apart at connections. Seems to be just the main lines. Using 1" poly pipe, plastic elbow, or t connectors and steel clamps. I've already gone through the whole system making sure every fitting was snug on the connector and clamps as tight as possible. Had system leak free just over 24hrs, and then boom! instant pool in the backyard. What am I missing? Any help or suggestions please?
