▪ When water tank is full, the O-Ring plunger[B] gradually comes down to the inside of the Tiered wall [A].

▪ Each wall of [A] has different heights and this special design can gradually stop the inlet water from 0% (ON) to 100% (OFF) without chattering and noisy.

▪ O-Ring plunger [B] can provide perfect sealing effect over 10,000 cycles (ON 3.2” OFF 1.8”)
