Pool Valve Settings

Valve Settings – Normal Pool Settings

In normal operation, water should be drawn in from the pool, but not from the spa.  It should return to both the pool and
the spa.  This way the spa overflows into the pool.  The drain on the spa is kept closed because if it was left open, the spa would drain back into the pool when
the pool pump is turned off.
