My weep water currently weeps on to the floor and then runs down the drain. I dont have doors and the wind blows through only on really really windy days. I noticed last winter the only major ice build up that would ever occur was only where my weep water hit. My thinking was that if I didnt have ice build up from weep water which causes lots of ice build up because of the constant water, then I would not need to have my floor heat set high to melt off large layers of ice.
