Product review (1 stars): Worked great for a couple of years. Update
Thought we had a good one until 30 months out it became erratic. When it stopped working entirely we called for service and were told the electronic controls were defective. Price to replace controls plus labor equals close to purchase price. Very disappointed in lack of warranty for substandard parts.

After repair noticed something in the back flow preventer. It was a small piece of wood, well worn and water logged. It had evidently made its way through the pump, and may have caused the controls to burn out. Will never know how it got into the drain system, as it is protected by a screen.
