But I tried to find out if that’s really not “acceptable building practice” or if I am confused. All I could find was reference to sloping the garage floor toward the door to allow drainage, but can’t find anything that specifically says a floor drain in garage is a no-no. I suppose there’s also the possibility that it’s not going into the sanitary sewer, but how would you know that unless you could water hose it and see if it came out into the yard somewhere.
