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 wha...
