Hi it is made for us and available thru me anywhere in the World. I sell a LOT of this system for more info please feel free to call me on my cell for direct access. 954.275.8373 Doug The way I have it here is with a 3/4 thermo valve and separate volume controls for each option. You can also use a Pressure balance valve with 3 way diverter. I can ship what you need tomorrow from Nebraska and have it in four days. Thanks Nice to hear from you. More common is Chrome then B Nickel but I can make it in black if you have the right amount of time. Have a great day!!
