ABSTRACT:
A device for effecting secondary circulation of water into a hot water tank not having a return opening. The arms of a T-fitting are place in series with the distribution line near the outlet port of the water tank. A return line, continuous at one end with the distal portion of the distribution line, is continuous at the other end with a relatively small internal line which lies within the leg of the T-fitting, one arm of the T-fitting, and extending through the outlet port into the water tank. A relatively low power pump and a sinking-ball valve are placed in series with the return line to cause the flow of water in the secondary circulation system to flow in one direction only.
