Had another thread trying to figure out water in our 'new' coach...
I finally figured out how to drain the main water tank. To sanitize, manual says to attach the "provided short hose" to the winterization port (see photo). But to fill the tank, I'm to use the city water hookup port with same hose. But the hose is not compatible with the winterization thingy. So can I put my bleach water in through the city water hookup to sanitize my tank?
What the heck use is the winterization then? Why is water coming out of it when I untwist the gray plug?
