(1) Hose connections or plumbing equipped with backflow prevention shall be installed that enable all parts of any pool or spa area to be reached with a hose for effective cleaning. The installed backflow prevention must be adequate to withstand the water pressure needed for the length of hose in use and to prevent back siphonage into the potable water supply system.

(2) Hose shall be properly stored when not in use to prevent a potential tripping hazard.

(3) Deck wash material and debris shall not be washed into the pool, spa, or other water feature and must be properly drained to prevent standing water.
