Abstract
A telescoping waterway component for use in firefighting equipment has a multi-piece outer tube and a telescoping inner tube through which fluid flows. An inlet component is selectively positionable at different inlet heights along the outer tube and can be positioned to provide different inlet angles. A rotating shutoff element is mounted within a manifold of the inlet component. The inner tube can be retracted to nest within a hollow cross-section of the shutoff element when that element is closed. A valve interlock disables an operator from rotating the shutoff element while the inner tube is retracted, or from retracting the inner tube while the shutoff element is open.
