I went out to the darkroom and opened the valves on my hot and cold supply. I have an old Kodak Dial Mixing valve with vacuum breakers on both incoming lines. As I increased the flow to get the temperature up there was a bang bang bang! Water shot out wildly all over the room and I was soaked. So what's the point of all of this?

Im tired of wandering temperatures and the constant checking and resetting. Anyone who has one of these dinosaurs knows what I'm talking about. It may be great for a riverboat engineer who needs something to do but not a darkroom worker.

Its finally time time to get a Hass Intellifaucet. The question is which model, D or E? Same price $$$.

I haven't found a better unit. Tell me about yours.
