1.1.1 General Requirements. This Standard establishes materials, testing, and marking requirements for suction fittings that are designed to be totally submerged for use in swimming pools, wading pools, spas, and hot tubs, as well as other aquatic facilities.
1.1.2 Definition. Suction fittings shall be defined as all components, including the sump and/or body. cover/grate, and hardware.
1.1.3 Compliance. Demonstration of compliance for this Standard is merely an indication that the product meets performance requirements and specifications contained in this Standard.
1.1.4 Revisions. The provisions of this Standard shall not be construed to prevent the use of any alternate material or method of construction provided any such alternate meets the full intent of the standard.
1.1.5 ExcLusions
1.1.5.1 Skimmers shall be excluded from evaluation to this Standard.
1.1.5.2 Vacuum connection covers shall he excluded from evaluation to this Standard.
1.1.6 Types of Suction Fittings
1.1.6.1 General. A manufachirer or designer of any suction outlet cover/grate shall indicate under which Type the cover/grate is listed.
1.1.6.2 FIeld Fabricated Outlets. All nonmanufactured suction outlets constructed in the field with mdividual components shall he considered as “Field Fabricated Outlets.”
1.1.6.3 Venturi Outlets. All venturi activated indirect-suction outlets or venturi activated debris collection systems shall be considered as “Venturi Outlets.”
1.1.6.4 Swim Jet Combination Fittings. All swim jet combination fittings that combine suction and discharge into one housing, creating a high velocity, high volume stream of water to swim, jog, or walk against. .is well as massage, shall be considered “Swim Jet Combination Fittings.”
7.1.2 As an alternate to marking field fabricated outlets, the owner of the facility where these fittings will be installed shall be advised in writing by the Registered Design Professional the information called for in paras. 7.l.1(b)(1) through (7).
7.2 Packaging of Suction Fittings
7.2.1 The packaging and installation instructions for manufactured fittings shall contain
(a) information on installation and service including
(1) type designation in accordance with para. 1.1.6, including any requirement for multiple outlets required per pump

(4) instructions stating that in the event of one suction outlet being completely blocked, the remaining suction outlets serving that system shall have a flow rating capable of the full flow of the pump(s) for the specific suction system
(5) maximum flow rating with head loss curve
(6) acceptable connecting pipe size(s)
(7) mounting position(s)
(8) suction outlet part number(s), and/or model number(s), and detailed field build sump design specifications, when applicable
(9) part number/description list, and “Replace within ‘YY’ installed years” for all parts
(10) tools required
(11) service and winterizing instructions
(b) a cautionary note not to exceed the maximum allowable flow rate stated on the suction fitting
(c) a note that the suction fitting including fasteners should be observed for damage or tampering before each use of this facility
(d) a statement that missing, broken, or cracked suction fittings shall be replaced before using this facility
(e) a statement that loose suction fittings shall he reattached or replaced before using this facility
(f) a statement “Read, then keep these instructions for future reference”
(g) a cautionary note about increasing flow by increasing pump size.
