Our patented MULTISTOP water trap has been designed with a
special seal plate which closes the water trap when not in use.
Thus, bad odors are prevented from penetrating from the sewer into
the room. In addition to functioning as a water trap and an odor
stop, our MULTISTOP water trap has a third function, as the special
seal plate used in the MULTISTOP water trap closes the water trap
in case of rising water from the sewer, preventing water rising
through the grating onto the floor.
