Figure 2. Typical Piping Installation
2. To help prevent difficulty in priming, install the
suction pipe without high points (above inlet
of pump - inverted "U"s, commonly referred to
in plumbing as an airlock) that can trap air. For
installations of equipment up to 100 feet from the
water, refer to Table 1, the pipe sizing chart. For
installations of equipment more than 100 feet from
the water, the recommended pipe size must be
increased to the next size.

1½" 37 GPM (140 LPM)
2" 62 GPM (235 LPM)
2½" 88 GPM (333 LPM)
3" 136 GPM (515 LPM)
4" 234 GPM (886 LPM)
3. ePump Series Pumps come equipped with
™
unions on both the suction and discharge ports.
This feature simplifies installation and service
and eliminates the possibility of leaks at threaded
adapters.
4. The Jandy Pro Series ePump must be connected to
at least two (2) hydraulically-balanced main drains
(suction outlets) for each pool pump suction line.
Refer to Figure 2. Each drain must be provided
with covers that are listed or certified to the latest
published edition of ANSI/ASME A112.19.8, or
its successor standard ANSI/APSP-16. The suction
outlets of the main drains must be at least three (3)
feet apart or at different planes. The suction outlets

can be a drain and skimmer, two (2) drains, two
(2) skimmers, or a skimmer with an equalizer line
installed. For additional details and guidelines,
refer to ANSI/APSP 7, the standard for Suction
Entrapment Avoidance in Swimming Pools,
Wading Pools, Spas, Hot Tubs, and Catch Basins.
Check the local codes for proper installation
requirements. Applicable local codes will take
precedence over other codes.
NOTE To prevent entrapment, the system must be
built so it cannot operate with the pump drawing
water from only one (1) main drain. At least two
(2) main drains must be connected to the pump
when it is in operation. However, if two (2) main
drains run into a single suction line, the single
suction line may be equipped with a valve that
will shut off both main drains from the pump.
5. The piping must be well supported and not forced
together where it will experience constant stress.
6. Always use properly sized valves. Jandy Pro
Series Diverter Valves and Jandy Pro Series Ball
Valves typically have the best flow capabilities.
7. Use the fewest fittings possible. Each additional
fitting has the effect of moving the equipment
farther away from the water.
NOTE If more than ten suction fittings are needed, the
pipe size must be increased.
8. Every new installation must be pressure tested
according to local codes.
