STS-50T Series

The D'MAND® STS-Series converts standard plumbed homes into D'MAND® Systems. At the push of a button, the STS -Series pumps cold water sitting in the hot water line into the cold water line and back to the water heater. The "off sensor" automatically shuts off the pump and closes the zone valve when hot water arrives at the system. Now you have hot water instantly at the fixture and anywhere else plumbed off of the main line.

The STS-50T models are smaller pump systems designed for smaller homes. They weigh 6 lbs. Dimensions are 8" wide, 7½" deep, and 5½" tall. (This model is not recommended for gas tankless water heaters. Please review the tankless water heater section on this site for further information.)

The patented PDV (Check Valve) is built into the pump housing, reducing the number of external devices. The STS-50T models are adequate for runs of under 50 feet. The STS-50T models carry a three year warranty.

The STS-50T is available in three configurations. The base configuration is the STS-50T-PF Kit. Pause your mouse over the other model numbers to see the differences in the photos.
