If you haven’t replaced yourshowerfaucet in the last few years, go take a look. With a single-handle set-up, chances are you have aMoentrol valve – the kind where you pull it toward you to activate the water and then twist it left or right for hot or cold.
Or, maybe you have a single-handle where you turn it counterclockwise from the “off” position and stop it when you get to the temperature you want. In that case, you might have aMoen PosiTemp valve in your shower.
In any event, both valves are marvels of engineering that have stood the test of the time and remain the most popular choice for millions of homeowners.
So, what’s the difference between a Moen PosiTemp valve and a Moentrol Valve?
First, let’s look at the similarities of the two valves. Both offer a pressure-balanced system that maintains water temperature within two degrees. Built-in temperature limit stops allow you to control how far the handle rotates, controlling the range of water temperature. Both are available in a variety of connections from common 1/2″ CC/Sweat, 1/2″ IPS threaded, 1/2 PEX or CPVC and meets pressure-balancing safety codes.
The differences lie primarily in operation.
The Moentrol has temperature memory. When you push the handle in to turn the water off, the handle stays in the exact temperature position you set during use. The next time you turn on your faucet, the water will reach your last temperature setting.
More, the Moentrol also gives you the ability to control the strength of water flow for your shower.
When you install a PosiTemp,you operate both the faucet and the temperature by turning the handle from the "off" position to where you find the water most comfortable, progressing from cold to hot the further you turn the handle.
The Moentrol valve is more expensive then the PosiTemp for the added feature of temperature control where you can set the temperature so it is always where you like it. Moentrol trims and valves start at around $100 each, and the PosiTemp begins around $35 for the trim and $70 for the valve.
