Merrill Manufacturing is proud to introduce our new H2O Pitless Control Unit. This is a patented, all-in-one solution for total control at the water well. The unique system has a built-in pressure tank, along with all the other tappings needed, such as a pressure transducer and a pressure relief valve. Also included is a mounting plate for constant pressure variable frequency drives within the unit. This significantly simplifies and reduces costs for installation and repair.
