Installing a Bilge Pump Installing a Bilge Pump

What You'll Need
Heat Gun
Screws and Bolts
Heat Tubing

When your boat gets flooded often due to excess water, it’s time to install a bilge pump. Bilge pumps are automatically activated when a boat takes in a certain amount of water. They keep the boat from sinking or tilting due to the accumulation of water. Bilge pumps are usually installed at the lowermost part of the boat. Additional pumps can also be placed at other locations to assist the primary pump during severe flooding. Installing a bilge pump properly can mean difference between saving or losing a ship during critical situations. If water reaches high level early on, it could disable the engines and short out electrical circuits. Follow these steps to properly install a bilge pump.

Step 1 - Know Where to Place the Bilge Pump

First, determine the lowermost level of the boat. Install the bilge pump securely by installing it to the floor with screws and bolts. Also check if the floating switch is functional. The floating switch is the bilge pump part which determines whether or not water has reached a critical level. 

Step 2 - Attach an Additional Hose to the Bilge Pump

In order to make the bilge pump perform more efficiently, attach a hose  to the bilge pump system. This will serve you well when water level rises too fast.

Step 3 - Make Sure the Batteries Are Safe

Some bilge pumps fail to work during critical situations because the battery was depleted too soon. Moderate the power output of the battery by adjusting the discharge above the waterline.

Step 4 - Secure the Wires

Sometimes bilge pumps also malfunction because the wires leading from the bilge pump to the bilge pump interior are submerged in water. Make sure these wires are waterproof by insulating them with heat tubing. Use the heat gun to make the tubing fit securely to the wires.

Step 5 - Calibrate the Power Supply to Run at All Times

Make sure that the bilge pump operates even if the boat engine is turned off. This can be done by calibrating the battery connection, making the bilge pump run independently from the boat engine.

Step 6 - Test the Bilge Pump

Test the bilge pump’s functionality by conducting a mock flooding scenario. Make sure that the water level reaches the floating switch in order to trigger the bilge pump. Take note of your bilge pump’s efficiency when it comes to siphoning excess water.
