Things to Consider Before Choosing a Saltwater Washdown Pump


There are different types and sizes of marine washable pumps available in the market. It is vital to have the knowledge to choose what is best for you and your budget. Apart from price, there are some factors to consider before purchasing saltwater washdown pumps. A good washdown should leave your surface clean.

1. Components of the system

The majority of standard marine washdown pump systems are available with a 12V DC. There are circuit protection, inline filters, connectors, wiring, a nozzle, and a hose.

2. Pump water flow rate

Pump water pressure is measured in gallons per minute. Most pump systems have a diaphragm pump within a range of 3.4 and 5 gallons per minute. Such is adequate to cater to the needs of small and medium-sized boats and decks. A 30-35 PSI water pressure will help eliminate the dirt faster.

3. Pump installation options

You should ensure your installed washdown pump system is accessible and not too visible. Most saltwater pumps can work in wet conditions. However, it is advisable to install the pump just above the bilge’s high watermark. The majority of boat owners install their pump systems under the gunwale or any other protected surface.

4. Wiring and switches

For washable pumps drawing 10 amps and less, an AWG 14 wire is recommended and is bound to give you a 3% voltage drop or less. It is essential to follow the manufacturer's guidelines for long wire with more amperage draw. It is vital to follow the boat's particular electrical distribution panel while wiring the washdown pump. If you lack a pane, it is advisable to install one. Installing an on and off switch close to the pump is recommended as well.

While shopping for pumps, it is good to choose marine-grade materials, wires, and connectors designed to withstand corrosion. Crimping all connections for durability and safety is also good. Kindly avoid corrosion and water intrusion by using adhesive-lined tubing to secure all connections. Finally, it is advisable to fuse your circuit with a breaker to protect the whole system effectively.

5. Pump Versatility

A good saltwater washdown pump is preferably one that can work in both fresh and saltwater. Getting one that can do both will help you escape unnecessary spending.

6. Size of Pump

It is vital to check the pump's size to ensure it is a good fit for your boat or decks. Some tend to be a little huge and heavy. A small and easily portable washdown pump is easy to install, handle and does not cause inconvenience.

7. Your budget

Having a budget is also important. Reasonable spending should get you an effective, functional washdown pump. An overpriced pump does not fully guarantee efficiency. In the same way, under-priced pumps do not mean they are not as efficient. Functionality is key when going for a pump that matches your budget.
