A. Inlets:
1. Swimming pool water recirculation system inlet shall be located so as to produce, so far as possible, uniform circulation of water throughout the pool without the existence of dead spots and to carry pool bottom deposits to the outlets.
2. The inlets shall discharge at a minimum depth of ten inches (10") below the pool overflow level.
3. A minimum of one recirculation system inlet shall be provided for every six hundred fifteen (615) square feet of surface area of the pool.
B. Make-Up Water:
1. Pools shall be equipped with suitable facilities for adding make-up water as needed.
2. There shall be no physical connection between the water supply line and the pool system. If the make-up water is added directly to the pool, the outlet shall be at least six inches (6") above the rim of the tank.
3. If a hose connection from a sill cock or other plumbing fixture is to be used for supplying make-up water, then an approved vacuum breaker shall be installed between the sill cock or control valve at the fixture and the hose connection. The vacuum breaker shall be installed at a height not less than seven feet six inches (7'6") above the floor, platform or ground upon which a person would stand when operating the sill cock or control valve. Maximum size of the fill-pipe is to be two inches (2").
C. Outlets:
1. In swimming pools thirty feet (30') in width or less, water circulation system outlets shall be located so as to provide at least one outlet at the deepest point in the pool.
2. If the pool width is more than thirty feet (30'), multiple outlets shall be provided and spaced not more than thirty feet (30') apart, nor closer than four feet (4') to any wall.
3. All pool drain outlets shall be equipped with gratings having an area of openings not less than four (4) times the cross-sectional area of the outlet pipe. The gratings shall be of such design so they cannot be readily removable by bathers and will not injure bathers' fingers.
4. One outlet shall be provided for each eight hundred (800) square feet of surface area.
D. Construction Specifications: The system supplying recirculated water and make-up water to the pool shall be constructed in conformance with the ordinances regulating plumbing. (Ord. 186-70, 7-13-70)
