Abstract
Abstract A separate pump is used for each car wash bay and a plurality of conduits extend from adjacent the pump to the nozzle boom in the bay. Each conduit carries a different solution such as wash water, rinse water and the like. Valves permit the operator to switch from one conduit to the other thus eliminating the necessity of emptying the conduits completely of one solution before the next solution is available.
