Cleaning the decks after a fun day on the water is exactly what the washdown pump was designed for. Whether you’re blasting away fish debris, mud from your anchor, spilled drinks, or bird droppings you need a washdown system that is equipped to get the job done in a flash.

PSI and GPM

PSI (Pounds Per Square Inch) and GPM (Gallons Per Minute) are both equally important when choosing a washdown system. PSI refers to the amount of pressure and GPM refers to the flow. The level of pressure (PSI) directly affects the system’s ability to strip dirt and grime from a surface and Flow (GPM) refers to the rinsing power or the system’s ability to carry the dirt away once stripped. Cleaning Units (CU) is the result of multiplying the PSI by the GPM…calculating and comparing the cleaning units will allow you to compare one unit to another.

As an example, a washdown system rated at 70 PSI and 5.2 GPM has 364 Cleaning Units.

Flow rate is generally more important to commercial applications as contractors generally rely more heavily on deck cleaners to do the heavy lifting. Therefore, rinsing the dirt away is typically their focus.

Hose and Quick Connect Fittings

Washdown systems are typically packaged with coiled hose for easy storage but if you’re replacing a worn hose you may want to consider a collapsible version as they stow away just about anywhere. Quick connect washdown fittings allow you to stow your pump behind the scenes and position the subtle connection points conveniently around your boat for easy access.

Panel Switches

When installing a washdown system on a boat not previously equipped with a washdown pump you will likely need a panel switch which will allow you to control power to the pump.
