What's the small reservoir behind panel over toilet?

Bandanaman

Thanks in advance.  I am not sure what this small white reservoir is, once you unlock and open the wall panel above the toilet.  I am wondering if this is where I put sanitizer?  I'm having some learning curves here.  

WINTERIZING: My 2014 CS-S has its line drain valves in the rear, under the sink and under the clamshell.  There are three.  They are pull up valves, not with valves. To winterize, is this correct--?

Drain gray and black water.  Open three drain valves noted above and drain.  Close valves and fill water reservoir with 2 gallons of pink antifreeze.  Pour about 12 oz down each drain.  Turn water pump on and then open one water outlet at a time until antifreeze is visible.  Flush toilet.   Hook up low volume air compresser to water intake and open one water outlet at a time.  Reopen and drain three in line valves, then leave open over winter. Re-drain black and gray water reservoirs. Run about two gallons of bleach through system in Spring to sterilize water lines.  Then drain bleach.  Run city water through system and good to go?

Am I close, I hope?  Am I missing anything?   I really don't know what glycol is all about in the Alde, either.  Pretty mechanical but this is all new to me!

Thank you all!  This forum is so helpful!

Can you post a photo? I don't have a panel above the toilet in mine. Do you have an Alde?

Actually, I see that small reservoir is the glycol reservoir for the heater.  Do I have to ignite the heater or does it do that automatically?

I'm presuming since you have glycol that you have the Alde heat system - think the others are forced air... If so, you should have a control panel with three sliders that control the Alde and it self ignites if you run it on propane. Like Jenn, I have a MaxS so our Alde reservoir is behind the back bench.

If they're  talking about the access door behind the toilet in the shower.... that's a filter for domestic water and has nothing to do with the Alde. The glycol tank is at the rear of the trailer.

sabel - yes, that's true. Do you know where the glycol reservoir is on a CS model - can't imagine it'd be way in the shower hatch as none of the registers are even close.
BandanaMan - What lead you to the conclusion it was the glycol reservoir - that would have a pink fluid.

We have an Outback not the clamshell but the glycol res. Has to be close to the boiler. Ours is next to the boiler.

I don't have one either, mine's where yours is - that's why I was wondering as I'm not familiar at all with CS models
