THere was a contractor here at one time(not in business anymore
) that routinely used home cheapo parts such as orbit and toro. not only is that bad(although they do work technically) but he would use the 2in pop ups for turf!!! why here in the midwest where our pipes are deaper and our grass is cut taller would you use those OR EVEN sell them here.
guy was a total ******, totaly incorrect designs, improper heads and placement and cheap parts. he was a lowballer and i had a conversation with him about a year before he went under about his isntalls. he blamed my mowing for broken heads on lots of properties he installed systems. i told him how it was and he got pretty mad! i told him if you installed sprinklers deep enough and not on ridgid risers to boot, the heads could not be mowed over and damaged when you mow at 4" like we do!
what a ****** he was, but he was in and out of business in 5 years. was a landscaper too, and way over designed spaces that now are complete jungles.
