Provide access for future service by leaving a
clear area around the pump. Allow plenty of
space above the pump to remove the lid and
basket for cleaning.
8.
If the equipment is under cover, provide
adequate lighting.

Piping Design & Installation
4A. Size of Suction Pipe
1.
Recommended pipe size for the suction side of
the pump is 2" for ¾ to 1½ HP. For 2 HP pumps
recommended pipe size is 2½". For 3 HP pumps
recommended pipe size is 3".
4B. Size of Discharge Pipe
1.
Recommended pipe size for the discharge side
of the pump is 2" for ¾ to 2 HP. For 3 HP pumps
recommended pipe size is 2½".
Note: All pipe sizes are able to withstand the
pressures the pump will deliver, but not the flow.
If the pipe is too small for the pump, or it is
elevated above water, the maximum gallons per
minute (GPM) may not be delivered.
4C. Installation Tips
1.
If the pump is located below water level, it may
produce higher pressure compared to an above
water installation. Isolation valves must be
installed before and after the pump to prevent
back flow of pool water during any routine
servicing that may be required.
2.
To help prevent difficulty in priming, install the
suction pipe without high points which can trap
air. For installations up to 100 feet from the
water, the recommended pipe size must be used.
For installations more than 100 feet from the
water the recommended pipe must be increased
to the next size.

The Jandy
™
Pump comes equipped with 2"
unions on both the suction and discharge ports.
This feature will simplify installation, service,
and eliminate the possibility of leaks at threaded
adapters.
4.
The Jandy™ Pump must be connected to at least
two separate suction points in the water. A drain
and skimmer, two drains spaced apart, two
skimmers, or a skimmer with an equalizer line
installed. Check the local codes for proper
installation.
5.
The piping must be well supported and not
forced together where constant stress will be
experienced.
6.
Always use properly sized valves. Jandy
™
Diverter Valves and Jandy
™
Ball Valves
typically have the best flow capabilities.
7.
Use the fewest fittings possible. Every fitting
added has the effect of moving the equipment
farther away from the water. Note: If more than
ten (10) suction fittings are needed, the pipe size
must be increased.
8.
Every new installation must be pressure tested
according to local codes.
WARNING
Do not pressure test above 35 PSI. Pressure
testing must be done by a trained pool
professional. Circulation equipment that is not
tested properly will fail, resulting in severe
injury or property damage.
