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.
The NOTICE label indicates special instructions that are important but not related to hazards.
- 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.
IMPORTANT SAFETY INSTRUCTIONS
Page 2 of 8 DUAL SUCTION OUTLET SET ISDUALSWG REV D
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
be caught in an opening of an outlet or cover.
- Potential for jewelry, swimsuit, hair decorations, finger, toe or knuckle to
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.

WG1048EW Suction Outlet Covers are rated for Wall or Floor at 72 GPM
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) “Floor Only” suction outlet covers are selected and mounted.
These covers are individually rated for 125 GPM. For a desired flow rate through the pump of 100 GPM, a minimum
pipe size from the Chart 1 is selected at 3”. At the desired flow of 100 GPM one cover could be partially blocked
and the other suction outlet flow would be below the rated 125 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) “Floor Only” suction outlet cover, rated at 125 GPM, and one (1)
“Wall or Floor” suction outlet cover, rated at 72 GPM are selected and mounted. For a desired flow rate through the
pump of 50 GPM, a minimum pipe size from the Chart 1 is selected at 2”. At the desired flow of 50 GPM either
cover could be totally blocked and the other suction outlet flow would be below the rated 72 GPM of the wall
mounted suction outlet cover. Note: Flow may be limited by entrapping force in dual suction systems.
