The Taco 223-5 2-inch Flo-Check Valve with IPS (Iron Pipe Size) connections is a reliable and efficient solution for preventing backflow in various hydronic heating and boiler systems. Here’s a breakdown of its key features and functions:


  • Prevents hot water from flowing back through the boiler when the circulator pump is off. This protects the boiler from overheating and potential damage.
  • Suitable for use in both horizontal and vertical piping installations.

Key Features:

  • Cast iron construction: Offers durability and corrosion resistance for long-lasting performance.
  • Threaded connections: Simplify connection to IPS piping (standard in hydronic systems).
  • Spring-loaded check valve: Allows for free flow in one direction and automatically closes to prevent backflow in the other.
  • Compact design: Fits easily into tight spaces.
  • Full-port flow: Minimizes pressure drop, ensuring efficient water circulation.
  • Temperature and pressure rating: Suitable for hot water systems with operating temperatures up to 277°F and pressures up to 125 PSI.


  • Hydronic heating systems (radiant, baseboard, fan coil).
  • Boiler systems.
  • Domestic hot water recirculation systems.

Things to Consider:

  • Pipe size: Ensure the valve’s size matches the diameter of your Iron Pipe Size (IPS) pipes.
  • Installation: Requires basic plumbing skills. Professional installation is recommended for optimal performance and safety.
  • Flow direction: Install the valve with the arrow pointing in the direction of desired flow.


  • Taco 223-5 2-inch Flo-Check Valve NPT: If your piping uses National Pipe Thread (NPT) connections, you’ll need this version of the valve.

Overall, the Taco 223-5 2-inch Flo-Check Valve IPS is a popular and reliable choice for preventing backflow in hydronic heating and boiler systems. Its durable construction, compact design, and full-port flow make it a suitable option for both homeowners and professionals.
