Here is the almost finished product for re-doing the water tank and lines. On the left is the inlet with a pull to open the valve to fill the water tank from the outside. I reversed the tank and it\'s fittings were in front and had the fill hose and overflow going to the fill hole up on the side. On the right is a plug where I can put the additives into the tank as needed. Below that, but not shown, is the tank drain valve.
