The Double-Sealed drain is designed to keep your home healthy with 3 innovative benefits. It is odor-free: an original feature adds an automatic stopper system to the traditional water trap. This brass automatic-stopper encloses the water so there is no evaporation or siphoning-off and guarantees there will be no odor, bacteria or flies from the water trap. It is easily installed as it includes as easy installation adjustment that can rotate and adjust the length, acting as a knee joint. It is also easy-clean, with a, pop-up, umbrella-shaped hair catcher that can be easily taken out to clean debris.
