DUAL SUBMERGED SUCTION OUTLET SET

[Commonly called main drains]

Basic safety precautions should always be followed, including the following: Failure to follow
instructions can cause severe injury and/or death.

This is the safety-alert symbol. When you see this symbol on your equipment or in this manual,

look for one of the following signal words and be alert to the potential for personal injury.

WARNING warns about hazards that could cause serious personal injury, death or major

property damage and if ignored presents a potential hazard.

CAUTION warns about hazards that will or can cause minor or moderate personal injury

and/or property damage and if ignored presents a potential hazard. It can also make consumers
aware of actions that are unpredictable and unsafe.

- WARNING - Read and follow all instructions in this

owner’s manual and on the equipment. Failure to follow

instructions can cause severe injury and/or death.

WARNING – Suction Entrapment Hazard.

Suction in suction outlets and/or suction outlet covers which are damaged, broken, cracked, missing, or

unsecured can cause severe injury or death due to the following entrapment hazards:

Hair Entrapment- Hair becomes knotted or snagged in an outlet cover.

Limb Entrapment- A limb sucked or inserted into an opening of a circulation outlet with a broken or missing cover
in the pool resulting in a mechanical bind or swelling

Body Suction Entrapment- Suction applied to a large portion of the body or limbs resulting in an entrapment.
Evisceration/ Disembowelment Entrapment- Suction applied directly to the intestines through an unprotected
sump or suction outlet with a missing or broken cover.

Mechanical Entrapment- Potential for jewelry, swimsuit, hair decorations, finger, toe or knuckle to be caught in
an opening of an outlet or cover.

To Reduce the risk of Entrapment Hazards:

o A minimum of two functioning suction outlets per pump must be installed. Suction

outlets in the same plane (i.e. floor or wall), must be installed a minimum of three feet (3’)
[.91 meter] apart, as measured from suction pipe center to suction pipe center. (See
Diagram 1. If suction outlets are to be located closer then three feet (3’) [.91 meter] apart,
they shall be located in different planes (i.e., one on the bottom, and one on the vertical
wall, or one on each of two separate vertical walls.) (See Diagram 2)

o Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage” by a user.
o Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas.
o The maximum system flow rate shall not exceed the flow rating of any listed (per ASME/ANSI A112.19.8M-1987,

ASME A112.19.8-2007, APSP-7) suction outlet cover installed.

o Keep suction outlet components clear of debris, such as leaves, dirt, hair, paper and other material.
o Never use a Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not securely

attached.

o Prior to each use of the swimming pool and/or spa, observe and replace damaged, broken, cracked, missing, or

not securely attached suction outlet components immediately.

o Remove pressure test plugs and/or plugs used in winterization of the pool/spa from the suction outlets.
o Two or more suction outlets per pump should be installed in accordance with latest APSP Standards and CPSC

guidelines. Follow all National, State, and Local codes applicable.

o Multiple layers of protection are available including installation of a vent pipe system, a gravity flow system, or a

vacuum release system.

o Suction outlet components have a finite life, the cover/grate should be inspected frequently and replaced at least

every seven years or if found to be damaged, broken, cracked, missing, or not securely attached.

o Do not exceed maximum flow rate stated on suction fitting.

o Only replace a pump with one with a similar flow curve, avoid a pump with a higher horsepower rating.
o To reduce the risk of body entrapment, installation of the field fabricated sumps must be such that the top of the

mounted WG1031BHF cover is a minimum of 1 ½” above; and the top of the mounted WG1032BHF cover is a
minimum of 1 13/16” above, the finished pool surface over an area larger than 40” on a diagonal.

WG1031BLV Suction Outlet Cover (Replacement sold as a WGX1031BLV) is rated for 108 GPM Wall Mounted or 190 GPM Floor Mounted for
single or multiple suction outlet use. (9” x 9”)
WG1032BLV Suction Outlet Cover (Replacement sold as a WGX1032BLV) is rated for 260 GPM Wall Mounted or 392 GPM Floor Mounted for
single or multiple suction outlet use. (12” x 12”)
WG1033BLV Suction Outlet Cover (Replacement sold as a WGX1033BLV) is rated for 520 GPM Wall Mounted or 520 GPM Floor Mounted for
single or multiple suction outlet use (This is a package of four 9” x 9” covers and frames) (18” x 18”)
In the event of one suction outlet being 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.
Example: In the System shown in Diagram 1, two (2) 12” x 12” suction outlet covers are selected and mounted on the floor. These covers

are individually rated for 392 GPM. For a desired flow rate through the pump of 120 GPM, a minimum pipe size from the Chart 1 is
selected at 3”. At the desired flow of 120 GPM one cover could be partially blocked and the other suction outlet flow would be below
the rated 392 GPM of the “Floor” mounted suction outlet cover. Since there are two outlets flowing in normal operation, and the
allowable velocity in the interconnecting piping is only 3ft/sec, the same pipe size is required in the interconnecting piping.

Example: In the System shown in Diagram 2, one (1) 12” x 12” suction outlet cover mounted in the floor, rated at 392 GPM, and one (1)

12” x 12” suction outlet cover mounted on the wall, rated at 260 GPM. For a desired flow rate through the pump of 200 GPM, a
minimum pipe size from the Chart 1 is selected at 4”. At the desired flow of 200 GPM either cover could be totally blocked and the
other suction outlet flow would be below the rated 260 GPM of the wall mounted suction outlet cover. Note: Flow may be limited by
entrapping force in dual suction systems.
