Depends where its stored. If its inside climate controlled.. then drain and run some water through it. If its outside, you need to run mix(water/alcohol) so it doesnt freeze.
You can also do nothing.
In my opinion, the pumps have a life of X amount of years sitting in alcohol.. if you cut down the percentage.. they should last longer. In water.. probably forever.

DO NOT MIX WITH ANYTHING OTHER THAN WATER!!!! If you mix with anything else those contaminants will be in your alky when summer comes and you don't want that..
