The MHR20 -550 does NOT require an in-tank float switch. Previously, it was common for these setups to require an in-tank switch that would rise/fall with the water and change the electrical signals accordingly. HYJETs modern and complete MHR setup is specially designed for quick and easy installation, so its switch over system is completely automatic. In the event of a dry water tank or power failure, the MHR Series does the thinking for you and automatically changes back to Mains supply.
