The Leak-Stop Valve is a great way to detect leaks and prevent floods. The Leak-Stop utilizes a super-absorbent pad that expands when it detects water. The expanded pad pushes a valve in the Leak-Stop and shuts off the water. Quick-Connect fitting allows you to easily install the Leak-Stop in seconds. Great protection around your sump, around your aquarium and near your water station.
Replacement pads are sold in packages of 5 pads.
