Featured Product: Taco Accu-Flo Balancing Valves

If you want four to five times greater balancing accuracy in your systems, try a Taco Accu-Flo Balancing Valve. The Accu-Flo utilizes a modified venturi design that is far superior to conventional valves with their variable orifice design that delivers poor balancing accuracy, high pressure drops, low regains and an inability to read low flows.

All brass interior parts, precision machining and 100% factory testing make sure the Accu-Flo delivers the quality and reliability you expect from Taco.

HVAC Pros Askā€¦

Question: I read that the D'MAND® On-Demand Water Recirculation System (008DM) can be installed at the water heater on new construction projects. How does that work?

Answer: In order for the D'Mand® System to work in new construction, the piping would have to accommodate a recirculation line back to the hot water tank from the farthest fixture in the system. A remote switch turns on the pump when you want hot water at the point of use. If no recirculation piping is installed, you would have to install the D'Mand System with the plumbing kit at the point of use, usually the faucet farthest away from the hot water tank. The instruction sheet and piping diagram on the D'Mand System page of this website should be helpful.
