2.3 Basic Plumbing
2.3.1 Plumbing for Pool and Spa Combination
The following plumbing diagrams illustrate
simplified versions of standard plumbing setups
for a pool and spa that share the same filter pump,
filter, and heater. The intake and return Jandy Valve
Actuators (JVAs) turn si mul ta neous ly so when the
Spa mode is selected on the AquaLink RS PDA,
water circulation switches between pool and spa
(consult the Jandy Valve Actuator Installation and
Operation Manual to ensure that the JVAs are
synchronized and rotate properly). Please consult
the Jandy Valve Plumb ing Manual for further
examples of pool/spa plumbing.

into the pool.
