Match the System to the Job

A bilge pump is not the same as a freshwater pump, a macerator pump, a raw-water pump, or a washdown pump. Flow rate, voltage, duty cycle, inlet and outlet size, head pressure, switch type, hose compatibility, and installation location all matter.

Choosing the Right Pump or Plumbing Part

Know the System

Freshwater, bilge, sanitation, raw-water, washdown, and livewell systems use different pumps, hoses, fittings, and safety requirements.

Match Voltage and Flow

Confirm 12V or 24V power, gallons or litres per minute, outlet size, pressure rating, duty cycle, and switch requirements.

Confirm Hose Size

Match inside diameter, hose type, fitting size, clamp style, and system use before replacing hoses or pumps.

Plan for Service Access

Pumps, strainers, valves, filters, macerators, and fittings should be installed where they can be inspected, serviced, and winterized.
