I have a new install at a new house that I am having problems with. I ran 6 heads per zone and I have upwards of #6 nozzles in rainbird 5000's to get the well to not cycle. I know the well cannot put out 20gpm, so what is the problem. If I run 3 gpm nozzles in the heads the pump kicks off every minute for 20 seconds and then kicks back on. If I run the big nozzles they do not perform very well. Here is the big problem, when the zones switch or the pump does kick off, with the bigger nozzles in the when the pump kicks back on it is violent. The pvb shakes so back you it sounds like someone ran into the house. Scared the **** out of the client last night. Here is the kicker, they said they heard a dripping in the laundry room and went in there and dirty water was dripping inside of the washing machine??? Help please.
