Hello TOM and thank you for the feedback you posted on the Home Depot website. The Moen Align Single-Handle Posi-Temp Valve Trim Kit in Chrome (Valve Included) comes with the Moen Posi-Temp tub/shower rough-in valve required for installation. The Moen Posi-Temp tub/shower rough-in valve has a single handle that only rotates to turn the water on/off and adjust the temperature. When the handle is moved to turn on the water it flows at full volume; there is no volume control with the Moen Posi-Temp rough-in valve. We are sorry that the Moen Align Single-Handle Posi-Temp Valve Trim Kit in Chrome (Valve Included) did not meet your expectations and we hope you will give us a try again in the future. Moen product specialists are available for pre-purchase, installation, and warranty assistance. They can be reached at 1-800-289-6636 and are available Monday through Friday from 8:00 am – 7:00 pm Eastern Time.
