I have a model 600 series Delta shower system. When having the hot water adjusted from the tub spout and then going to the shower head some hot water is lost and you have to add more hot water to the mix?
Thank you for your question. If you have a unit that is not pressure balance, and the water pressure on the cold side is higher than on the hot side, you may need to readjust the temperature when diverting to the shower head. Since the flow through the shower head is lower, there is more back pressure.
