The KM-PF-1 is designed to be plumbed into a home's incoming water supply pipe , where it will reduce sand , grit, debris ,pipe scale and other loose particulate matter from the water and periodically flush them down the drain . It can be used as a pre-filter for the center water filter and softener .

Otherwise , the electronic controller can runs by a transformer or on a 6 volt battery . the controller will indicate when the battery need to be replaced . it will be very easy .
