It’s after Labor Day so I can post this winterization question. Boat is stored inside, heated. I usually run the fresh water tank empty and leave it at that. This year I have a fresh water pump that is acting up and I’ll be working on it and possibly replacing it over the winter. Plan was to do it early, say November/December, And then run the tank dry once everything is fixed. Any issues? Should I put some form of water treatment in? Thanks in advance.
