General Pool Equipment
Refer to the following guidelines and the diagram below.
1. Spa should be at or above the level of the pool. For raised spas: Provide a means for the spa to overflow
into the pool and install check valves in the spa return and the pool suction (see diagram) to prevent the
spa draining while the pool/spa suction and return valves are rotating. If spa is not attached to pool: An
overflow pipe of sufficient size to carry full pump flow must be installed between the spa and pool.
2. Plumb 3-way valve on the suction side of the filter pump, so that center port of valve is connected to the
filter pump. Connect spa suction to one port, and pool suction to the other port.
3. Plumb appropriately sized spa makeup line (incorporating a manual valve and a check valve). During
pool circulation, some of the pool water needs to enter the spa to keep it chemically balanced and full of
water. The ball valve adjusts the amount of bypass.
4. Systems with separate main drain and skimmer lines can use a 3-way valve to balance the flow.
5. If a pressure side cleaner requiring a boost pump is used, plumb the pump in the pool return (after the
pool/spa return valve).
6. A valve actuator (connected to Aqua Logic Valve3 or Valve4 output) or a pump (connected to Aqua
Logic Aux output can be used to direct pool return water to a waterfall.
7. Plumb solar system supply and return lines between the filter and heater. Install a 3-way solar valve
(connected to Aqua Logic Valve3 or Valve4 output) and/or a solar booster pump (connected to an Aqua
Logic Aux output).
8. The plumbing diagram below is intended to be used as a general guideline and is not a complete plumbing
schematic for the pool. The diagram shows more equipment than can be controlled with an Aqua Logic
system.
