What is this?

I have a 2018 Forester 2401 WSD on a Mercedes chassis. This is located in the bathroom right below the shower.

I assume that valve switches the water input from the fresh water tank (current position) to the winterizing tube.

The valve and the notice are independent.

The notice is telling you that you dont have an elbow trap, but instead have a waterless trap and warning you that a drain snake would harm it.

Here is a link to a well known company that makes waterless traps instead of p-traps found in most installations.....just look underneath your sinks at home to see typical p-traps.

A lot of campers will have three valves that you need to open or close depending on what you are trying to, mine has the same winterizing switch yours has, it shut off water/RV antifreeze to the water heater. If you are going to use RV anti-freeze to winterize the camper then switch it to the winterize position, this only allows the water pump to pump water to the campers pipe's and not to the WH. I would even switch it to winterize if I was just going to blow out my lines with air. When you do winterize don't forget to open the low pint drains and outside shower if equip'd. In the spring when you go to de winterize don't forget to put that back to normal.

Thanks and another question is what is the winterizing tube? Nothing in any of my manuals on this......
