Asni objective of this standard is to provide recommended minimum guidelines for suction entrapment avoidance in the design, equipment, operation and installation of new and existing swimming pools, wading pools, spas, hot tubs and catch basins for builders, installers, pool operators and service professionals Maximum water velocity limits are: Solid barriers which do not have openings, such as a masonry or stone wall, shall not contain indentations or protrusions except for normal construction tolerances and tooled masonry joints.

The walk area shall be constructed of impervious material, and the surfaces shall be of such as to be smooth and easily cleaned and of nonslip construction.

Section AG – Barrier Requirements: There shall be no physical connection between the water supply line and the pool system. These design controls are intended to provide protection against potential drownings and near-drownings by restricting access to swimming pools, spas and hot tubs. Where the barrier is composed of diagonal members, such as a lattice fence, the maximum opening formed by the diagonal members shall not be more than 1.

The swimming pool and equipment shall be equipped to be emptied completely of water and the discharged water shall be disposed of in an approved manner that will not create a nuisance.

Every swimming pool shall have a recirculating system with an hourly capacity equal to the pool volume divided by eight 8 i. Pressure filters shall be equipped with readily accessible air relief valves, loss of head or pressure gauges on the inlet and outlet pipes, and an access head or hole large enough to permit inspection, maintenance and repair work. However, the area within the swimming pool barrier, excluding the swimming pool and walk areas, shall not exceed one thousand two hundred forty 1, square feet.

Section AG – Abbreviations: A receptacle for water or an artificial pool of water intended for the purpose of immersion or partial immersion therein of human beings having a depth at any point of more than two feet 2’placed in an excavation.

Standards Subsctiption may be the perfect solution. Steps and ladders shall have a handrail on both sides. Pools shall be equipped with facilities for completely emptying the pool and the discharge of the pool water shall be at a rate not exceeding two hundred gallons per minute.


The design features shall be as follows: For the purposes of this combined or total measurement and the application of this section, any swimming pool shall be considered as having 4 sides, based upon the 4 most significant changes of direction.

The gratings shall be of such design so they cannot be readily removable by bathers and will not injure bathers’ fingers. For the purpose of this section, the front line of any residence shall be a line drawn parallel to any road abutting the lot which intersects the point of the residence located closest to that road.

A fence, a wall, a building wall, the wall of an aboveground swimming pool, or a combination thereof, which completely surrounds the swimming pool and obstructs access to the swimming pool. Sight glasses that can be easily removed for cleaning shall be provided in effluent line from the filter units. The answers to the above stated questions were given with the understanding that the said questions are to be considered individually and not collectively. Pool pump motors shall not be split-phase, shaded-pole or capacitor start-induction run types.

This definition includes inground, aboveground and onground swimming pools, hot tubs and spas.

If the document is revised or amended, you will be notified by email. The following words and terms shall, for the purpose of this chapter and as used elsewhere in this code, have the meaning shown herein: No swimming pool shall extend two feet six inches 2’6″ or more aboveground. If a hose connection from a sill cock or other plumbing fixture is to be used for supplying makeup water, then an approved vacuum breaker shall be installed between the sill cock or control valve at the fixture and the hose connection.

This standard is not included in any packages. Maximum system flow is not defined in this standard; the flow requirement is that the equipment shall be sized to provide a turnover of the pool water at least once every twelve 12 hours.

All discharged water shall be drained entirely upon the property on which the swimming pool is located and shall not flow on any adjoining property. Your Alert Profile lists the documents that will be monitored. No current carrying electrical conductors shall cross private residential swimming pools, either overhead or underground or within fifteen feet 15′ of such pools.

No pool hspi be drained into ndpi septic system or septic field or be drained in such manner as to cause such septic system or septic field to malfunction or to contribute to the malfunction of any such septic system or septic field. Any outdoor swimming pool shall be completely enclosed by a barrier which shall not be more than fifteen feet 15′ from the edge of the walk areas as required by this chapter; and the combined measurement between the edge of said walk areas and said required barrier as measured nsip the farthest points of separation on nspii of the four 4 sides shall not exceed thirty two feet 32′ in total.


These suction outlets shall be piped so that water is drawn through them simultaneously through a vacuum relief-protected line to the pump or pumps. Barriers shall be located so as to prohibit permanent structures, equipment or similar objects from being used to climb the nepi. Maximum size of the fill pipe shall be two inches 2″. The swimming pools’ circulation systems shall consist of pumping nepi, hair and lint catcher, filters, together with the necessary pipe connections to the pool inlets and outlets, facilities and pipe connections necessary for backwashing filter, and filters, and facilities and equipment for disinfecting the pool water.
