(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 no longer than 50 feet. 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) The water volume and water pressure for hose connections must be sufficient to provide effective cleaning.

(3) Deck wash material and debris shall not be washed into the pool, spa, or other water feature.
