Getting ready to install my equipment and I was wondering if there is a need to run everything in copper? Is it for apperance or is there something more to it? Can it be done with CPVC just as well? Also can anyone chime in on layouts for your equipment room? I have a small room 8*20 and I will have my self serve, automatic, foam brush, triple foam, air compressor, water softener, vac it up system, plus RO machine. I would like ideas from you experienced guys so I can lay it out the best way and not regret it later.
