I had our Tab winterized by a local RV shop last October, but we want to de-winterize it ourselves. I'm following the Tab owners manual steps to De-winterize and Sanitize with the Alde system, specifically method B (AF added to the fresh water tank, plumbing lines, P-traps, tank valves - sparing the Alde water tank).
Step 1 says "Valves are in the 'winterize mode' (AF bypasses the Alde how water tank, but runs through all water lines). Drain valves and hot and cold water supply valves should be closed...")
I know where the drain valves (C & E below) are but in the diagram below, which are the "hot and cold water supply valves" referenced in the manual?
