®
VSD pump.
Illustrations apply to WhisperFlo IntelliFlo VSD.
Pump Strainer Basket
The strainer, sometimes referred to as the “Hair and Lint Pot,” is in front of the of the pump.
Inside there is a basket which must be kept clean of leaves and debris at all times. View the
basket through the top see through lid to inspect for leaves and debris.
Regardless of the length of time between filter cleaning, it is most important to visually inspect the
hair and lint pot basket at least once a week. A dirty basket will reduce the efficiency of the filter and
possibly the heater.
