Customer had us over due to controller issues. Program A is supposed to water in the mornings then B during the evening. A was coming on during evening time which was because it also had a 9pm start time. I removed the evening time for A A zone was seemingly dry. Only had 1 MP head so we added 2 heads. While we were excavating, we noticed a kinked pipe which could have been why other techs believed the zone to have too low of pressure to add heads.
