I have never lost siphon but I do use fuel injection hose clamps sold at any auto parts store. These are hose clamps that are much better than the standard hose clamps as they apply a much mre even pressure and dont have those little grooves in them that eat up hoses. They area much better quality and made to stand up to greater pressures and they only cost a few cents more, like $.49 each but never had a leak with out them, I just want to keep it that way. The cleaner the room the less chance of fruit flies and less work also.
