Regulate water flow or seal off hoses for easy filter cleaning Disconnect valves are installed just above the filter to regulate flow or so the filter can be disconnected from the tubing. These valves allow you to seal off hoses so you can clean your filter without spilling water. Single valve stops water flow from aquarium. Double valve stops water flow from both aquarium and canister filter. Both help regulate flow from output side of canister. To shut off and disconnect both lines in both directions, you will need to order 2 double-disconnect valves.
