2017 Citation Low point water drain valves

[Sluftig]

I’m working on winterizing my 2017 Citation. It should be really easy but I can’t find the low point water drain valves. I found the water tank drain valve and was looking for a blue and red pipe under the chassis with valves on them. I found two blue pipes under the chassis one is the water tank drain. The other blue pipe has no valve. Called Thor they told me I have a blue and red pipe with valves under the chassis, I don’t, they sent me piping diagram that shows 2 Drain lines with valves, they are not there. My outdoor shower is the low point for both lines so I drained those, am I OK? What is the other blue pipe without a valve under the chassis. Any advice would be helpful.

That’s all I do.

Thanks, does anyone know what that second blue line is for? Could it be some kind of vent?

FW tank overflow/vent line would be my guess. That is what it was on my 2002 5er.

Now that makes sense. I asked Thor tech support to confirm. I’ll let you know what they say when they get back to me. Thanks!

my 2011 Keystone sprinter has a vent at the FW fill port. No 2nd pipe under the trailer. No low point drains either.
