Tank Ro/di & Drinking Water

[TANGOMAN]

Thanks Mark! I always wondered what the purpose of that was. Now I wonder what the check valve on the ro housing is for...? Anyone in Calgary sourced out replacement solenoid valves locally? If I actually get this functioning normally again do I have to put the electronic solenoid valve in the back yard again this spring? It has dials and lcd display, all the essentials for a cool looking fish room...LOL

I'm afraid to look back and see if my original question was answered.
