Re: Buried PEX for irrigation system
Thanks! Yes, I could see some runs being 170 feet long just to get to the zone area. May need 1.5" PEX pipe for that which is certainly pricey. I've actually never heard of this Blu-lock pipe, I'll definitely look into it more. Quick search makes it look like it only goes up to 1". So poly pipe would be good also for these long runs? Thanks again!

Re: Buried PEX for irrigation system
Thanks everyone. I ended up using a master valve and 1.5" PVC anywhere else the 1" Blu-lock wouldn't cut it due to pressure loss. The Blu-lock was really easy to work with. I don't know how easy the poly pipe would have been, but I would have given up if i had to use pvc cement on all those fittings!
