SEPARATE POOL & SPA PLUMBING
Heating a separate pool & spa, "without" a spill over, with one heater. Two pump system.
The following schematic is the suggested plumbing set up when using the dual thermostat kit. This design is for
"separate" pool and spa combinations, where the two are totally isolated from one another. The motorized valve
turns so that the heater is isolated to either the pool or the spa when the dual thermostat is activated by the user. The
motorized valves shown can be manual if automatic operation is not desired. Please note the 10 pound spring
valve and ball valve used as a bypass when the valves are turning. This will eliminate the possibility of "dead
heading" by the user.
NOTE: An exchange of water between the pool & spa may occur. This will depend on pump size, pipe size
and equipment distances. The possibility of the spa flooding over or draining should be considered. Most
commercial pool/spa codes do not allow this type of plumbing set up.

Remember: If either water pump is over 2 HP,
the excessive water flow valve will be needed.
