In operation, the MicroSweeper turns on at 41 degrees (F) and turns off at 42 degrees (F). The MicroSweeper is plumbed near the float valve, usually in the port where the petcock was installed. It is a thermal sensing valve that is constatly in contact with the water & "intermittently" releases enough pressurized water to prevent surface ice as the water temperature dictates. No more-no less. The intermittent flow MicroSweeper can be easily plumbed in any type of waterer, no matter how it was originally equipped. The MicroSweeper requires no maintenance, no electricity and no adjustment, EVER. The MicroSweeper is designed an manufactured to provide a long life in tough conditions and to deliver unexcelled performance. The quality construction and very precise control ensures the most economical usage of water and the least amuont of labor in preventing waterer ice formation for many years.
