THRU-HULL INSTALLATION

A two pump system is the preferred system of boat builders wanting to provide a superior livewell. A simple two pump system provides a back-up in the event of pump failure.

FIRST SYSTEM: Install a standard livewell pump such as a Rule 500, 700, or 1100 GPH to exchange water occasionally in the well. When using a  ¾" pump inlet, a 1 ½" drain such as the KA109 is required.

SECOND SYSTEM: Install either the KA700RK or KA110RK. This will allow fish to remain healthy while the standard livewell pump is off when the boat is in contaminated water, or when the pump is air-locked. Many boats have the livewell pump installed on the transom. When the boat is on a plane, the intake of the pump is out of the water and is ineffective. The boat can also be trailered while the bait remains in the livewell. This system always remains on while fish are in the well.

Valve A open, B closed -- outside water flowing through livewell
Valve A closed, B open -- recirculating livewell water only
Valve A closed, B closed -- strainer D can be cleaned
Valve A open, B open -- livewell will drain
Check valve C prevents back flow
