Mid Water Intake

This Mid water intake is intended for liner pond side wall mounting.
Typically used on ponds in colder climates which are set up to operate throughout the year.

The pond keeper switches (via control ball valves) from primarly bottom drain suction to these side wall intakes during the cold winter months. This allows for temperature stratifiction of the water column, providing bottom pond temperatures to remain relatively warmer.

Can also be used on our fiberglass pond shells, all models.
The intake can also be used as a bottom drain on our smaller fiberglas model pond shells.

Use 4" x 13" filterbrush or similar for periodic cleaning in-place
