Background: My Sun Valley has two tanks, but only a single-hose regulator. Translation: A huge PITA when I have to get up in the middle of the night to change the hose after the heater goes out. So, I bought and installed a dual-tank, auto switch regulator today. The original regulator had a single hose that came out of the top of the regulator and connected to the tank. No problem. The new regulator has two hoses (obviously) that come out of the regulator on either side. Herein lies the rub, quite literally. The hoses press right against the tanks, with a fair amount of pressure. Also, the regulator screws onto the bracket backwards, so I can't see the empty tank indicator or the knob that indicates which tank is being used. I'd like to relocate the regulator, and have a few questions. First, how hard is copper hose to work with? Do I even have to use copper, or can I use flexible gas hose? Second, where do you all have your regulators mounted? Thanks in advance.
