What is your water volume? 2" could be overkill!

Your approach is good and a master valve at the POC is recommended. I agree with RVLI with the PVC mainline and Poly laterals.

Use 2" mainline in PVC, laterals in Poly. Just make sure you blow your lines out before winter.....

Long mainline

I am planning an irrigation system on a site where a large section is greater than 250 feet from the point of connection (PVB at building). I am planning on extending a 2 inch dia. mainline to this area (250 feet) then placing several valves at that point for laterals.

I am worried about the risk of damage to this line due to its length and size. To minimize damage if there is a break I am placing a master valve near the point of connection.

Some questions:

1. Is this a good approach? If not what are options?

2. If I use a master valve can I consider everything beyond as a lateral and use poly instead of SCH 40 PVC? From other posts on forum PVC was recommended for lines 2 inches and above but I live in a freezing climate (Minnesota) and am concerned about breakage due to frost.

Any help would be welcome.
