Buyer’s Guide


There are countless things to consider when looking for a washdown pump, and I bet there are tons of questions on your mind right now. Every pump displays a massive strength that helps boaters flush unwanted dirt that is sitting on the decks. Now, let us untangle the factors one by one.

Always look for a higher pressure

High-pressure pumps are undeniably superior. You can have superior performance with them because they wash away dirt in no time. If you want a faster cleaning operation, you shouldn’t think twice and pick the models with at least 60 PSI.

A pump isn’t efficient if it lacks protection

Thermal and ignition protection is common in pumps, but several ones offer extra protection like corrosion, diesel, oil, and water resistance. Sometimes, having all of these features in a water pump could be costly. Hence, it still depends on your application. Never overlook this tip.

Choose Pulsation and Noise-free

Nothing’s more frustrating than a noisy water pump. Who would want an ear-splitting pump? As much as possible, always select a pump with little to no pulsation/noise. It creates a disturbance-free washdown routine.

Consider checking the warranty details

Warranty is sometimes underrated. People always focus on the primary specifications, but with washdown pumps, you have to be careful. There are stores online that don’t provide the warranty as advertised. Since it is a machine, there’s always a big chance that you can experience problems with it. It’s inevitable and natural, so don’t miss checking the warranty out.

Use credible sources online to help you with your queries

You might want to check the hull truth forum for a thorough discussion. If you haven’t read it before, you should consider it now. It contains a cornucopia of information about boating and fishing.

What Does a Washdown Pump Do


It is a device that helps marine enthusiasts eliminate junks left on the boat. It washes away all deep-seated specks of dirt that seem difficult to put away. It enhances the sanitary process and reduces the cleaning duration.

How Do Washdown Pumps Work

Washdown pumps release water supply from an external source. The pump pumps the raw water with an ample amount of strength and pressure. Then, it uses a washdown hose to drain the content out of the deck.

What is the Top-Rated Saltwater Washdown Pump

Happybuy and SHURFLO washdown pumps are excellent. I’ve seen many fishing hobbyists and sailors use them for intense resistance against rust and corrosion. Both are tough choices in marine environments.

How Do You Install a Washdown Pump on a Boat

Let’s assume you’re in this section because you haven’t bought one yet, and you want yourself to be familiar with this area, so let’s begin.

First, mount the pump in a dry place of the bilge. Allow at least 6 feet in height from the water intake.

Second, connect the hose from the fitting port to the termination locations in the front and the back. The front side should be near the anchor locker, and the backside should be attached to the bulkhead.

Third, affix one side of the check valve to the intake line. Connect the other side of the valve to the hose connected to the inlet port of the water strainer. Make another connection from the strainer outlet to the inlet fitting.

Lastly, from the T fittings, run the hoses to the drilled holes used for joining bulkhead parts. Use clamps to secure the hoses. Then install the remaining connections on the deck and connect the pump to a power source.

In doing all of these steps, make sure to secure a drill gun, correct fittings, hoses, screws, clamps, and of course, the pump, and you’re all set.

Care and Maintenance

Some of us are not machine-savvy, and that’s okay. We rely on mechanical professionals for help. But in taking care of the washdown pump, you don’t need to know everything about it.

You can take care of it by practicing proper routines. Make sure you have a thru-hull to stop the hose’s water supply after cleaning.

You can also winterize the pump during the winter season to add maximum protection. Likewise, avoid overheating the pump. Although most pumps have thermal protection, it is still advisable not to depend on it all the time. Use seal to avoid any leakage.


Every boater needs to equip their boat with washdown pumps, as they provide an effective remedy to keep it as fresh as new. There are options like boat grooming services that can instantly give your vessel a Cinderella-like transformation, but they are expensive and impractical.

The existence of the best washdown pump provides a long-term solution to back-to-back filthy boat problems. It is a vital part of the boat’s system that shouldn’t be taken for granted. It won’t hurt to invest in what keeps your luxury escapes at sea enjoyable. If you care more about the other types of boat pumps, you can refer at boat water systems above.
