Questions & Answers

Q:What powers the water valve open when the float trips? The float has a wire running from it to the valve, I don't see how water pressure can be activated by the float alone?

1 Answer
Answer This Question

A:  What you are describing as a wire, is not a wire. It is a tube. The rising float ball pushes an air column through this tube which actuates the diaphragm in the water valve. The water valve then allows for the flow of water which in turn creates the pumping action. So, the answer to your question is air pressure.

    Answer This Question

    A:  Sorry I am unaware of this product having a specific design life. For that you may want to speak to the manufacturer directly. Base Products can be reached at 716 876 5206. They are in Buffalo New York so due to the state of emergency there, due to the blizzard, you may have trouble reaching them. As to the warranty. If you scroll down the Home Depot product listing page you will come to a section entitled Product Details where you will find product details. The 5 year warranty is outlined there in detail.
