The wand is a highpressure remote hydraulic cylinder that is plumbed to a footswitchactivated pump. After the fixture is cleaned of debris and the operator mounts a new part, a shutoff valve—located in the circuit just after the fixturemounted booster—is opened. The operator then inserts the wand into the booster.
