The MIFAB® Model # WCTSP-1 is designed to provide two ounces of a water prime every time the toilet is flushed. It is an easy retro-fit to existing toilets and uses existing water that is wasted when the toilet is flushed to prime floor drain traps within twenty feet of the toilet. A continuously sloped 5/8” OD copper make-up water line should be installed between the WCTSP-1 and the floor drain trap.
