Im just getting into sprinklers and was wondering what you think of my price. 4 zone system. 12 RB 5004, 18 RB 1804, 4 DV valves, and Pro mod controller. Im gonna run a main line for my valves. Im using sch40 pvc from the tap through the backflow and then 200 from my valves to the zones. im going to use approx. 100' of sch40 and 700' of 200. Im trenching since its my first install. Ive added everything in like valve boxes, wire, glue, fittings, etc. The material came out to $965.00 after %30 markup and tax. My labor is the same. so the total for a 4 zone system is $1930. How am i doing?
