design work is completed, gathering parts and getting close to re-doing my entire back yard irrigation with MP Rotators. Couple questions: How close to a chain link fence should I install heads? I do plan on connecting heads to the laterals with no more than 18" of flex hose. What do you think of gluing the flex hose to pvc connectors instead of using the barbed fittings? Guys at the irrigation places I have been haunting insist that gluing is THE way to go. yesterday I discovered that the local Home Depot rents a trencher. $56 for four hours and $80 for the day. Any tips or tricks on trenching you want to offer? I live in Florida and soil is mostly sand.
