The Monitor PS Domestic Pitless Unit forms a sanitary, frost-proof connection with all water passages below the frost line. Spool sealing lets the entire inner assembly lift out of the casing for service, and patented O-ring seal protection prevents seal damage during installation.
Threaded style connects to a male-threaded casing (or via welding nipple, pitless connector, or swagged nipple). Supplied as a spool without check valves, less cap; order the well cap separately. Select well size and bury depth.
