Not a problem, fast efficient and showed up on time. The only problems are that I was distracted by a neighbors dog in the yard and did not receive the info needed to cover the one year warranty on the pump. The second problem was that everyone, myself included, failed to open the drain from the holding tank that went to the pump. I realized there was a problem when the water pressure dropped on the front area irrigation area. I opened the valve and the system worked as it should.
