Figure 1: Normal operation: float
valve open.
If water level is too low, the pump may remove all water
from the skimmer causing the float valve to close, diverting
pump suction to equalizer (or main drain) line allowing
some water to reach the pump. Float valve will remain
closed until pump stops. If pump starts again before
stoppage is cleared, float will close again until pool water
level returns to normal.
WARING! LOW WATER LEVEL CAN MAKE IT DIFFICULT TO
EXIT POOL AND MAY DAMAGE PUMP AND OTHER POOL

EQUIPMENT.
Note: An equalizer line is a way to bypass the skimmer
and it is intended to prevent damage to the pump when
pool water level is below the throat of the skimmer or
the basket is full. You must check your local code as some
require equalizer lines, others don't allow them and others
leave it to the pool designer. When equalizer line is used
the cover inside the pool must be VGb compliant, meeting
the requirements of ASME/ANSI 112.19.8a-2008 or ANSI/
APSP-16.
