RadonAway Hi-Per Drain (TM) Standard

SuperSump Floor Drain Kit includes: a Cup, ball, lid and 2 screws. The SuperSump Floor Drain Kit can be used in a sump or floor drain. Water can go down, but air can’t come up. This will stop radon gas as well as humidity and odors, when they are a concern, and can even stop cold air from coming into the basement when there is a connection to an outside drain of some kind.
