Will be a weathermatic system with SL800 controller and SLM10 weather station. Plot is ~20,000sqft and mostly flat, contractor is doing head-to-head spacing with rotors @ 30' distance. He will tap into the 1" line going into the basement after it enters the 5/8" meter, by my calculation this will provide for 15gpm. I assume he should be using 1.5gpm for 90 degree heads, 3gpm for 180 degree heads and 6gpm for 360 degree heads which would result in 1" per hour if the heads are 30' apart length or width? The reason i'm so concerned with precipitation rate is that the smart controller / weather station runs it's own runtimes with accordance to PR, soil type, slope and shade. feedback would be appreciated, too late to do it again once it's done if it's not right!
