Now for your stinky water, have you drained and rinsed your water heater?

Blowing out the lines may be fine for folks in the south, however, it is not sufficient for folks in the north were winter temps drop below 0 for days at a time.

On my coach, the winterization and sanitation system (same system different solution) first puts the solution in the fresh water tank and then the valve is switched over to normal use and the pump is used to circulate the solution throughout the system. If the solution is not first pumped into the fresh water tank, it will not be circulated through the pump or the line from the tank to the pump. This also holds true if someone uses a hand pump to winterize through the city water connection.

Some after market winterization / sanitation kits (depending on how they are installed) will pull antifreeze through the pump without going through the tank. However these systems generally by pass the line from the tank to the pump and the strainer leaving them unprotected.
