These days, having a water pressure system on your boat is considered standard equipment, even for boats that only occasionally travel to coastal destinations. Water pressure systems make rinsing dishes, brushing teeth and hair, and showering more convenient and less labor-intensive than filling a bucket and pouring water over your head. They also enable the use of more sophisticated shower heads, which can vary the temperature and pressure of the water stream, and make it easier to rinse hair and soap up quickly. Most boats have one or more water pressure systems, but they’re not all the same. They vary in the water pressure they produce and the force with which they spray water.
Here’s what to look for when shopping for boat water pressure pumps.

Best Boat Water Pressure Pumps Buying Guide
Before choosing the best boat water pressure pump you should consider following options:
1. Power source: If you intend to use the pump on the water, you will have to buy a waterproof model. If you intend to use the pump for non-water related activities, you can buy a regular one.
Waterproof pumps are generally battery-operated, but there are also models that can be run on electricity as well. The type of power source you choose will depend on your needs.
2. Portability: All pumps are not created equal. Some are bulky and difficult to transport while others are compact and lightweight, making them easier to carry around.
If you plan on moving the pump from one location to another often, make sure it is easy to carry or has a convenient handle.
3. Horsepower: This refers to the amount of air pressure the pump can generate. The higher the horsepower, the better the performance.
While choosing the horsepower, keep in mind that bigger is not always better. You can always opt for a pump with higher horsepower but with lower RPMs, which means it will be able to run for a longer period of time.
4. Flow rate: This is the amount of liquid the pump can move in a specific period. The higher the GPM the better. If you plan on pumping liquids at a faster rate, you will need a pump with a higher GPM.
5. Tank size: All pumps come with a built-in tank for holding liquids. Make sure the tank of your pump is large enough to store enough liquid for your particular job.
The larger the tank, the more efficient the pump will be. You can always opt for a pump with a larger tank if you plan on using it for extended periods.
6. Noise level: All pumps emit some noise, but some are louder than the others. If you plan on using the pump in an area where the noise may cause a disturbance, make sure you buy a quieter model.
