I don't remember how the return lines were setup.
Thanks Evan, I'm stoked! Gonna be a little bit before starting the 110. I need to tear out the carpet and have hardwood put in that room first. Also, thinking about drilling through to the basement for the sump, auxiliary equipment, RO/DI, and water tank. And there's a nice drain down there for wastewater and to plumb to for emergencies.
Who was it that told me they have the color card for the Marine Test Kit, at their house in Thornton? I forgot your name, sorry!
