Abstract: An in-line vacuum breaker for a flexible hand held shower. The vacuum breaker includes a frusto-conical body with a water flow passage extending therethrough. The frusto-conical body has an inlet cavity at one end and an outlet cavity at the opposite end. An outlet plug is threaded into the outlet cavity. A first passage formed in the outlet plug leads to an outlet opening. A second passage in the outlet plug extends parallel to the first passage and leads to a vent opening. A manifold passage defined in the outlet cavity by the body and the outlet plug connects the body passage and the first and second passages. A first check valve in the first passage permits fluid flow only from the manifold passage to the outlet opening. A second check valve positioned in the second passage prevents fluid flow from the manifold passage to the vent opening. A third check valve positioned in the body passage permits fluid flow only from the body inlet opening to the manifold passage.
