Do you see any 'lines' under the rig?Low point drains have to drain out somewhereFind the lines and then look inside in that general area........under seating, inside cabinets, under bed, inside any storage, near fresh water tank etc.Scavenger Hunt ----woo-hoo  :B

Yep, crawl under the rig and look for 2 (or 3) hoses coming out through the floor and ending. They may or may not have caps on them that need removing.

Mine are all the way to the rear on the drivers side. You have to lay down and look up just in front of the hitch. There is a red and a blue pipe with silver 1/4 turn valves, the same as the hot water heater bypass valves. Once you know where they are you can reach them without getting on your back.

Thanks, on my 2001 they were readily visible, valves reachable from the inside. Wind is gusting at 40mph, 49 degrees. Sunday will be in 60's,will look then.

On my 2011 Four Winds the low point drains are directly under the bathroom. That puts them right behind the passenger side rear mud flap. My bathroom is over that wheel well.

I called Thor and they sent me an email showing the plumbing of the rig.

Now I can get to them by feel.
