ABSTRACT:
A pressure testing apparatus for a fire hose utilizing a source of water under relatively low pressure and flowable at relatively high volumetric rate. The apparatus employs a manifold using a hose filling valve. The source of water communicates with the manifold and a low pressure inlet of a pump. The outlet of a pump pressurizes the manifold at a relatively high pressure. Check valves prevent back flow from the manifold to the source of water and the outlet of the pump. A regulator valve is positioned in the manifold to determine the highest pressure found in a portion of the manifold for filling and testing the fire hose.
