What is the difference between a PosiTemp® tub and shower valve and a Moentrol® tub and shower valve?

While the valves do have several similarities:

  • A pressure-balanced system that maintains water temperature within ±3°F (1°C)
  • Built-in temperature limit stops which allow you to control how far the handle rotates, therefore, controlling the range of water temperature
  • Best water flow for any comparatively priced valve
  • Available in a variety of connections from common ½" CC/sweat, ½" IPS-threaded; ½" PEX or CPVC
  • Meets pressure-balancing safety codes

There are a few differences to consider before making a decision.
