How to Install a Taco Circulating Pump


Taco circulating pumps are manufactured for both residential and commercial applications. Established in 1920, the Cranston, Rhode Island company manufactures hydronic system components and heat transfer products. Its circulating pump is designed to keep hot water circulating through a home's plumbing lines rather than just sit in a water heater tank. This means that when you turn a faucet on, hot water is available instantly.

  • Turn off the water supply to the water heater and the electrical power supply as well. Once off, turn on the hot water in your kitchen faucet to drain all hot water out of the lines. Wait for the hot water supply line on the water heater to cool.

  • Unfasten the hot water line going to the water heater with a wrench. Wipe the hot water line's end off with a rag to dry it. Wrap plumber's tape around the end.

  • Fasten the hot water line to the Taco circulating pump with a wrench. Be sure to install the Taco circulating pump so the water flows away from the water heater and not toward it.

  • Connect the other line on the Taco circulating pump to the water heater's hot water line; tighten it with a wrench.

  • Repeat Steps 2 through 4, connecting the cold water lines to the Taco circulating pump.

  • Turn the hot water off in your kitchen sink, then turn the power and water supply back on to your water heater. Set the Taco circulating pump's settings to your desired values, following the instructions in the owner's manual, if necessary.
