Title: Aqua Stop - keeps your water in tank, not on floor!
Review: Excellent invention for quickly servicing the filter. First lever stops both inlet & outlet at the same time. Second lever releases the Aqua Stop with both hoses attached from the filter making servicing easier (since both will have water in them will ALMOST eliminate the need for priming).
