A washdown pump is used to spray saltwater over the deck to rinse it off, clean off fish and bait, or remove mud, sand, and dirt from your anchor, lines, or dinghy. Saltwater washdown pumps can break down, wear out, or clog over time, making them less efficient or completely non-functional.
Replacing a saltwater washdown pump on your boat is a relatively straightforward process that can be accomplished with a few basic tools and some careful planning. Here is a step-by-step guide on how to replace a saltwater washdown pump on your boat.
Gather the necessary tools and supplies:
Before you begin, you’ll need to gather the necessary tools and supplies for the job. Here’s a list of what you’ll need:
- Replacement saltwater washdown pump
- Screwdrivers (Phillips and flathead)
- Pliers
- Wrenches (adjustable or socket)
- Thread sealant (Teflon tape or liquid thread sealant)
- Hose clamps
- Hoses
Step 1: Turn off the power and water supply
Before you begin, it’s important to turn off the power supply to the washdown pump, as well as the water supply. If your pump is connected to a battery, simply disconnect the battery cable. If it’s connected to shore power, turn off the power source. Then, turn off the water supply valve so there’s no water running through the system.
Step 2: Remove the old washdown pump
Start by locating the washdown pump. It’s typically located near the stern of the boat, either inside a locker or under a hatch. Once you’ve found it, use a wrench to disconnect the hoses from the pump. If the hoses are clamped to the pump, use pliers to loosen the clamps.
Next, use a screwdriver to remove the screws that hold the pump in place. There may be several screws, so be sure to check all around the pump to ensure you’ve removed them all. Once the screws are removed, gently lift the pump out of its mounting bracket.
Step 3: Clean the mounting area
Before you install the new washdown pump, it’s important to clean the mounting area. Use a clean cloth to wipe away any debris or corrosion that may have accumulated. This will ensure a tight and secure fit for the new pump.
Step 4: Install the new washdown pump
With the mounting area clean and dry, it’s time to install the new washdown pump. Start by applying a small amount of saltwater-resistant silicone sealant to the bottom of the pump. This will help prevent water from seeping into the boat through the mounting area.
Next, carefully place the pump in the same location as the old pump and secure it with the mounting screws or bolts. Then, attach the hoses to the pump using new hose clamps and tighten them securely with pliers or a wrench. Make sure to use thread sealant (Teflon tape or liquid thread sealant) on the threads of the hose fittings to ensure a leak-free connection.
Step 5: Test the new pump
Once the new pump is installed and connected, turn the power back on and test the pump to ensure that it is working properly. Turn on the water supply and activate the pump using the switch or breaker. Make sure that water is flowing through the hoses and that there are no leaks around the fittings.
Step 6: Secure the hoses
After you have confirmed that the new pump is working properly, secure the hoses to prevent them from moving or coming loose. Use zip ties or hose clamps to secure the hoses to the boat or to other fixtures to prevent them from rubbing against anything that could damage them.
Step 7: Dispose of the old pump
Dispose of the old pump properly. Check with your local waste management agency to determine the proper way to dispose of an old pump.
Conclusion:
Congratulations, you have successfully replaced the saltwater washdown pump on your boat! With the new pump in place, you can enjoy the benefits of a clean and efficient washdown system that will make cleaning your boat a breeze.
