Washdown pump kit features

Washdown pump kits are essential for boat owners to keep their vessels clean and well-maintained. Here are some key features to look for when considering a washdown pump kit for your boat:

Performance:

A good washdown pump kit should offer a strong and steady water flow with adequate pressure to effectively remove dirt, debris, and stains from your boat. Look for pumps with a higher water flow rate, typically measured in gallons per minute (GPM), and a higher pressure rating, measured in pounds per square inch (PSI). For example, the SEAFLO 55-Series Washdown Pump Kit offers 5.5 GPM and 70 PSI, making it a powerful option for boat owners.

Durability and Construction:

Washdown pumps should be constructed from durable materials to withstand the marine environment. Look for pumps made from ABS plastic or with a sturdy Santoprene construction, which enhances the pump's longevity. Some pumps also offer additional protection features like corrosion resistance, thermal protection, and ignition protection, which prevent the pump from overheating and ensure its longevity.

Ease of Use and Installation:

Consider a washdown pump kit that is easy to install and use. Some kits come with all the necessary components, including the pump, hardware, hose, and sprayer, making installation a breeze. For smaller boats, a portable washdown pump kit like the TRAC Outdoor Portable Washdown Pump Kit is a great option as it conveniently runs off a direct battery source or your vehicle's cigarette lighter.

Noise Level:

Choose a washdown pump that operates quietly, without creating piercing sounds or pulsations. This will ensure a disturbance-free washdown routine for you and those around you.

Warranty:

When investing in a washdown pump kit, consider the warranty offered by the manufacturer. A longer warranty period provides added peace of mind and protection in case of any issues with the pump. For example, the SEAFLO 55-Series Washdown Pump Kit comes with a 4-year warranty, ensuring a frustration-free purchase.

Additional Accessories:

Some washdown pump kits come with additional accessories like a trigger nozzle, quick-connect adaptors, hose hammocks for storage, strainers, and various connectors. These accessories can enhance the functionality and ease of use of your washdown pump.

By considering these features, boat owners can make an informed decision when choosing a washdown pump kit to maintain the cleanliness and value of their vessel.

Washdown pump maintenance

Installation:

• Choose a suitable location for the pump, preferably close to the water source and power supply, to simplify wiring and plumbing.
• Ensure the pump is installed according to the manufacturer's instructions, including the use of an intake filter to prevent debris from damaging the pump.
• Use reinforced hose for plumbing, especially on the pump's suction side, to prevent hose collapse.
• Double-clamp all hose transition points with marine-grade, stainless-steel clamps for a secure connection.
• If drilling through cored decks, seal the edges of the hole with thickened epoxy to prevent water intrusion and potential rot.
• Bed the outlet fitting with a suitable marine caulking for added protection.

Routine Care:

• Always close the thru-hull after cleaning to stop the water supply and prevent leakage.
• Winterize the pump during the colder months for added protection.
• Avoid overheating the pump. While most pumps have thermal protection, it's advisable not to rely solely on this feature.
• Use seals to prevent any leakage and regularly inspect for wear and tear.
• Consult a professional for more complex maintenance or repairs.

Troubleshooting:

• Check for proper voltage and wiring connections. Ensure the wiring gauge is appropriate for the pump's amperage requirements to prevent voltage drop and overheating.
• Clean or replace the strainer/filter regularly, especially if operating in gunky or muddy waters, to avoid clogging and reduce the risk of pump damage.
• Ensure the pump is mounted securely and above the waterline to prevent flooding in case of plastic fitting failure.
• For plastic fittings, consider replacing them with more durable materials like stainless steel for added peace of mind.
• Periodically turn on the pump for a few seconds to keep the impeller well-lubricated and prevent it from sticking in one place.

Washdown pump installation

Washdown pumps are a great way to keep your boat clean and free of stains from fish guts, water, spilled food, and mud. Here is a step-by-step guide to installing a washdown pump in your boat.

Step 1: Choose the Right Location and Mount the Pump

First, choose an accessible and dry location for the pump, minimising the length of plumbing pipes and electrical wires. Most pumps need to be installed in areas that stay dry. Mount the pump to a sturdy and rigid part of the boat, such as a bulkhead, using a rubber insulator to reduce vibration and noise. If you don't have an appropriate platform, you may need to bond one in place. Remember that pumps don't have to be mounted horizontally; they can be fastened vertically to a bulkhead if that is more convenient.

Step 2: Connect to a Seawater Line

If your boat already has a seawater (or raw water) line, add a T-connector or Y-connector into that line to supply the washdown pump. If there is no existing seawater line, you will need to install a new thru-hull fitting with a seacock shut-off valve to supply the pump.

Step 3: Install a Washdown Outlet Plate (if needed)

If the washdown pump is installed below deck, you will need to install a washdown outlet plate through the deck. Run the pump's outlet hose to the underside of the outlet plate, and attach a regular hose and spray nozzle to the topside of the outlet plate for cleaning.

Step 4: Electrical Connections

Use marine-grade wire of the correct gauge for the amps your washdown pump draws. Add marine-grade crimp-on butt connectors with heat-shrink tubing for all connections. Run the pump's electrical circuit to and from your boat's electrical distribution panel, ensuring it has its own fuse or breaker. If your boat doesn't have an electrical distribution panel, run the circuit directly to and from the battery, with an inline fuse close to the battery terminal in the positive wire. Install a waterproof on/off switch for the washdown pump.

Step 5: Additional Tips

• Use a marine-grade hose with a higher PSI rating than the pump's capability.
• Install an accumulator tank after the pump's outlet and check valve to reduce water pressure spikes and prolong the pump's lifespan.
• Add an inline strainer or filter between the thru-hull and the pump's inlet to prevent debris from causing damage.
• Ensure there is a check valve at the pump's outlet to stop any backflow.
• If the pump is in a storage locker, connect a coiled hose to the pump's outlet hose and keep it stowed until needed.

By following these steps, you will be able to effectively install a washdown pump in your boat, making it easier to keep your boat clean and well-maintained.
