PUMP
Plumbing
This 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 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.
Best practice – Use two stainless steel hose clamps to attach hose to hose barb.
Periodically remove, clean and inspect the pump and its surroundings for damage
or debris that may reduce the performance of the pump.
