Well, I finally got around to trying to put some bleach water in my fresh water tank for sanitizing. Turns out that Pump Switch (inside the water station door) is exactly the same switch as the one inside the coach on the control panel. It does NOT pump water into the fresh water tank. I think this switch is just so you can control running water through the faucets (inside) without actually going inside and pressing the pump switch. I was hopeful that this was a well thought out "built-in" pump for pumping anti-freeze or bleach water into the fresh water tank.
As a result, I decided to just order this
for now, to pull my 4 gallons of bleach water into the fresh water tank.
I should have read the reviews a little closer, this may just be junk. If it is, I think I'll go with this
