    • HCG created this special flushing system to offer people “silent” toilet for a tranquil bathroom.
    • The silent flush is achieved through the special rim and trapway configuration which creates the vortex action under the water’s surface. This means the water in the trapway is actually “locked”, isolating the flushing noise down to 30db.
