so there is a new sub being built with about 100 homes... all over 700k... in an ongoing effort to beat off the "lowballers" and to get the first few systems in there to set up the yard signs.... I am looking at really trying to set myself apart... I already use the I-20s but think I will trying selling the strainless steel by claiming "only the cheap irrigation companies still use cheap plastic heads"... anyway.. I would like to offer a 5 year warranty on most parts (rotors, sprays, valves, and controller (and rain sensor?)) point being... I know I can do it on rotors and sprays.. but are there any valves or controllers that offer 5 years? I cant find it anywhere... only Rainbird and Hunter though..
