This particular rough-in valve is perfect! We use this one, because it is a high-flow unit. All the other units fail on this point, as they are catering to California's overbearing regulations. We also like this unit due to it having shutoff points for both the hot and cold water. This means that the valve can be fully installed and have the house water restored to the customer while we complete the repair/remodel work. We only wish that one could purchase this high-flow unit with a tub port.
