4.1.1 Plumbing Guidelines
Using the correct pipe size (pipe diameter) is important
for the efficiency and effectiveness of the entire system.
Pump model and distance to water (pipe length) are used to
calculate the recommended minimum pipe diameters below
(see Table 2). The number of suction fittings and pump
height relative to the water should also be considered.
NOTE If more than 10 suction fittings are needed, the pipe diameter
must be increased to the next larger size.

Table 2. Minimum Pipe Diameters
1. Use the fewest number of fittings possible to maximize
plumbing flow efficiency. Use sweep elbows for 90
degree joints wherever possible (see Figure 8).

2. Always use properly sized valves. Jandy

Valves and Ball Valves offer superior flow capabilities.
3. Unions on both the suction and discharge ports simplify
installation and service while minimizing leaks at
threaded adapters.
4. Piping must be well supported and not forced together
where it will experience constant stress.
5. To ensure easy priming of the pump, avoid creating
air locks in the plumbing (looks like an inverted “U”
shape). Below are examples of good and bad plumbing
practices (see Figure 9).

(Air Locks Created)
BAD
(90° Elbows Too Close to Pump)

6. Every new installation must be pressure tested
according to local codes.
