What is the difference between a PosiTemp Æ tub and shower valve and a Moentrol Æ 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:
Handle Operation – ñ how the faucet is turned-on and off.
Temperature memory – When shutting-off the faucet, the handle stays in the exact temperature position you set during use. The next time you turn-on the faucet, within a few seconds, the water temperature reaches your last temperature setting.
Volume Control – Controls the water flow rate so you get the amount of water you want at the temperature you want.
Flow Out of Unrestricted Tub Spout – the gallons per minute of water flow through the tub spout.
