Plumbing
This bilge pump has been designed to be used with flexible hose. Rigid piping or
tubing may damage the pump or the pump's discharge.
Factors that reduce the flow of a bilge pump may include but are not limited to
the following:
• The length of discharge piping (longer runs reduce flow)
• The number or radius of bends
• The roughness of the interior surfaces of piping and fittings (smooth bore
hose is best)
• The reduction (hose restriction) in cross-sectional area of discharge system
components such as check valves and thru-hulls
Attach the discharge hose to the hose barb using stainless steel hose clamps.
The thru-hull discharge fitting should be mounted at least 8" (20.3 cm) above the
heeled water line to prevent water siphoning in from outside the vessel or the
discharge may be located below the maximum heeled waterline if the discharge
line is provided with both of the following:
• A seacock installed in accordance with the requirements of ABYC H-27,
Seacocks, Thru-Hull Connections, and Drain Plugs, and
• A vented loop or other means to prevent siphoning into the boat. A check
valve shall not be used for this purpose.
If the discharges of several pumps are manifolded to discharge through a single
thru-hull fitting, the system shall be designed so that the operation of one pump
will not back feed another pump, and the simultaneous operation of each pump
will not diminish the pumping capacity of the system. A check valve shall not be
used in the discharge manifold system.
A check valve may be used only when necessary to prevent an automatic bilge pump
from cycling on and off due to back flow from the discharge line.
Hose connections shall be secured with a non-corrosive type of clamp, or be
mechanically fastened with permanently-attached end fittings, such as swaged
sleeve. Threaded inserts shall be attached with corrosion resistant metallic clamps.
Best practice: Use two
stainless steel hose clamps
to attach hose to hose barb.

During the winterization of a vessel, it's recommended that you remove the check
valve (if equipped) and drain any residual water from the plumbing.
Periodically remove, clean and inspect bilge pump, check valve and its surroundings
for damage or debris that may reduce the performance of the pump.
Installation
Push tabs on either side of the pump to remove pump
from the base.
We recommend using #8 stainless steel flathead screws of an adequate length as
to secure the pump but not penetrate the entire thickness of the hull. Use a flexible
sealant in the screw holes to prevent water from penetrating the screw holes.
Insert the pump into the base and push down until an
audible "click" is heard.
