This versatile pump is designed primarily for use in draining in-
ground pools for the purposes of maintenance and liner re-
placements. The slotted “basket-type” base measures less than
5 ½” in diameter. This dimension in conjunction with the (4)
cored reliefs @ 90 degrees apart, allows it to fit inside the drain
and seat itself several inches below the top surface of the main
drain flange, thereby draining ALL the water in the pool. It can
also be used in Irrigation, Pond and any other general watering
or de-watering application.
WARNING : POOLS ARE DANGEROUS TO SMALL CHILDREN.
NEVER LEAVE CHILDREN UNSUPERVISED NEAR A POOL.
