What the heck is this?

Iím stumped - my 2016 Sprinter Citation has a threaded water line end and a power switch in the utility bay. Thor customer support says the threaded water line is for rinsing out the black tank, and has no idea what the power switch is for.

You can see the water line (with a black plug, to the left of the main water fill) and the black switch just above it in the attached picture. The switch looks like it would control a light, but there isnít one.

Iím a little cautious about filling water into the mystery line as it looks like itís connected to my water input...and if this is to flush out the black tank, then thatís too weird!

Any information would be much appreciated!

I would suggest it for the water pump, so you can use the outside shower.

The outdoor shower works fine without having used this...really at a loss to figure it out! At first I thought maybe it would pump in antifreeze to winterize, but no such luck.

I am tempted to hook up a water line at the next dump station to spray out my black tank, but the way this seems to be attached to the water line gives me the willies!

I found this at https://www.rvroundtable.com/wp-cont...nual4-2014.pdf

It appears that is used to fill the fresh water tank; same valve body but brass plumbing instead of PVC. I'm guessing the black switch might be to turn on the water pump.

The main water line is to fill the fresh tank, or pressurize the main water lines. the small line is to pump in potable antifreeze to winterize the system. The main input line has a check valve.

The switch is for the water pump when using the outside shower. Both that switch and the inside (control panel) switch operate the water pump. IF either switch is on the pump is on...

Hooray and thank you!!

I tested the switch; you’re right, it’s for the water pump. Cannot say I am impressed with Thor’s customer service, who told me the switch purpose was unknown and the water line was to flush out the black tank. I very nearly attached a “dirty” rinsing hose at a sani-dump a couple of weeks ago to flush out the black tank; that would have contaminated my water lines.

Many, many thanks!

Glad you solved the mystery. Those kind of things can be frustrating.

If you haven't already, you might want to download the info from the link I put in my reply above. It's actually for a 2015 model, but I suspect there were not many differences between 2015 and 2016 models.
