No need to take it off
Rich, if you're talking about the base plug at the bottom of the head, I have never taken it off when winterizing after doing it one year and cracking the base which I then had to replace. I pump the holding tank out, rinse thoroughly with fresh water and then pump it out again. Then I put a gallon of non-toxic antifreeze ("the pink stuff") in the tank. Lastly, I pour about 2 quarts of the stuff in the bowl and pump the head as dry as it will get. If you do not want the antifress in the base, insert paper towels, let it soak and pull out. 6 times with 2 sheets crumpled at the base does it for mine. Good Luck
