What will work off a 3 outlet shower valve

Hi Linzi

Need more info. Here, OK? What size pipes feed the shower? What size is the water heater/storage tank system? What are you considering installing? What is the name brand on the valve? What size ports are on the valve... 1/2" or 3/4"? What size pipe is the main water supply to the house?

Answer these questions and I'll see what I can tell you, OK?
