Raw Water Washdown Systems: Installation, Maintenance & Troubleshooting Guide

What Is a Raw Water Washdown System?

A raw water washdown system is an indispensable addition to any fishing boat, utilizing the surrounding water to efficiently clean decks, fishing gear, and other equipment. These systems prove particularly valuable for anglers and boaters who frequently encounter saltwater fishing environments, fish slime, and various forms of marine debris. By employing a raw water washdown system, boaters can conserve precious fresh water resources while maintaining a consistently boat clean. This is a separate washdown pump to maintain water pressure for all the equipment. If you're looking for professional boat plumbing services, experts can assist with installation and maintenance.

Key Components

The efficacy of a raw water washdown system hinges on several key components:

Pumps

Both diaphragm and centrifugal washdown pumps are used to deliver the necessary water pressure. An Electric Diaphragm Washdown Pump is a frequently chosen option, known for its efficiency and ability to manage water flow effectively. When considering options, it's important to evaluate the pump output and pump self-priming capabilities to ensure it meets the requirements. Moreover, the Blaster II Washdown Pump is another reliable choice for maintaining a strong flow. A raw water pump is also crucial for optimizing water intake and system efficiency.

For those looking for high-performance marine pumps, Johnson Pump Aqua Jet is a well-respected brand in the industry. The Aqua Jet Wash Down series provides powerful cleaning capability for boats of all sizes.

Hoses

Durable wash down hoses are essential to transport raw water from the raw water pump to the spray nozzle. Many boaters prefer a black hose, which is durable and resistant to marine conditions. A quick disconnect system ensures efficient hose replacement and secure connections.

Nozzles

Adjustable spray nozzles allow boaters to control the water flow, accommodating various cleaning tasks and ensuring thorough coverage. A Blaster Nozzle or Thumb Lever Nozzle can provide additional flexibility, making it easy to switch between different spray patterns.

Check Valves

A check valve plays a crucial role in preventing backflow, ensuring that the bilge pump discharge hose remains free of contaminants and that the bilge pump functions properly. This is especially important for previous owners of boats who may need to replace old or faulty check valves to maintain system efficiency.

Benefits of Using Seawater

Opting for seawater in washdown systems presents a multitude of benefits:

Freshwater Conservation

• Reduces reliance on fresh water for cleaning, especially critical during extended voyages or in water-scarce environments.

• Fresh Water Pumps can also be integrated for additional flexibility when switching between fresh water and raw water washdown.

Effective Cleaning

• Seawater exhibits remarkable effectiveness in eliminating salt, fish slime, and assorted marine debris from decks and equipment, keeping everything spotless. Many previous owners of boats recommend investing in a washdown pump kit to maintain cleanliness effortlessly.

Livewell Maintenance

• Keeps livewells immaculate and devoid of debris, fostering a healthy environment for baitfish and promoting successful angling endeavors. The use of an aerator pump will further promote the health of bait.

Choosing the Right Washdown Pump

Selecting the correct washdown pump is paramount for optimizing system performance. Factors to consider include boat size, frequency of use, and specific cleaning requirements.

Pump Types

Diaphragm Pumps

Widely recognized for their self-priming capabilities and resilience to clogging, the Electric Diaphragm Washdown Pump Kit remains a dependable choice. For heavy-duty needs, consider an Electric Heavy Duty Diaphragm Washdown Pump. Diaphragm Water Pumps also include 12V DC RV Fresh Water Pumps, which are perfect for smaller vessels.

Centrifugal Pumps

Optimal for high-volume applications, albeit requiring cleaner water to prevent impeller damage and uphold system efficiency. A Johnson Pump Aqua Jet is often recommended for its high-flow rate and reliability.

Key Specifications

When procuring a raw water washdown pump, meticulous attention to these specifications ensures informed decision-making:

• GPM (Gallons Per Minute): Denotes the pump's water flow rate, with higher GPM values translating to greater water volume for expeditious cleaning. A gallon per minute pump ensures efficient water distribution.

• PSI (Pounds per Square Inch): Quantifies water pressure, where elevated PSI values signify enhanced cleaning prowess for tackling stubborn grime and stains.

Installation Guide

Tools and Materials

• Seacocks: Integral for safe and secure connection to through-hull fittings.

• Ball Valve: Used to regulate water flow. A 3-way valve may also be useful in multi-directional water routing.

• Marine-grade wiring: Essential for all electrical connections.

• Pressure Switch: A Heavy Duty Pressure Switch ensures consistent water pressure throughout the system.

• Anchor Chain: Helps secure hoses and prevents them from shifting.

Maintenance & Troubleshooting

Regular Flushing

• Flush the system with fresh water after each use to prevent mineral buildup.

Common Problems & Solutions

• Pump Runs But No Water Flow: Check for clogged inlet strainers, faulty pressure switches, or airlocks in the system.

• Low Pressure or Leaks: Inspect the bilge pump, water pump, and pump output for blockages or worn diaphragms.

• Electrical Failures: Clean corroded pressure switch contacts or check for a circuit breaker trip.

Conclusion

Investing in a raw water washdown system guarantees efficiency, convenience, and durability. Regular maintenance will keep your system reliable for years.
