The first thing ya want to do is have it dump back into the tank, that way your floors are dry and your salinity is stable. My skimmer does this on occation. and after 2 floods on the carpet (boy does that make the wife mad :angry) I fixed it so it will dump back into the tank if this happens. My collection cup drains into a 3 liter bottle. I put an emergency drain on mine so if it fills up to the top it will then and only then dump the water back into the tank. It works real good and no more floods. Try it

Good luck
