What is an indirect cross connection?
An indirect cross connection is a temporary cross connection that may exist for a short time. A good example of an indirect cross connection is a garden hose with the end of the hose submerged in a pail, sink, swimming pool, or pesticide dispenser. Some people use the garden hose to flush out sewers and drain pipes.
