I took another look!

Hi,. I crawled around under and inside the various cubby holes, cabinets and drawers. I even took pictures, I'll try to post some of those. I found the low point drains. Both are sticking out of the "belly" on the street side, one red one blue, right behind the rear axle. But can not find valves to open and allow drainage. I noticed some extra valves around the water heater. Besides the ones that are used to bypass the water heater. So I Think they may be the ones.
Thanks, bill b.
