Boat Fresh water pumps

Marine water pressure systems are the heart of your boat's plumbing. They ensure a constant flow of fresh water to taps, showers, and toilets. Choosing the right model depends on the size of your boat and the number of outlets. An undersized system will struggle to maintain pressure, while an oversized model will consume more energy than necessary.

Jabsco, Flojet, Marco, and Osculati are among the most trusted brands in the industry. They offer quiet, efficient, and corrosion-resistant systems. Always check compatibility with your boat's voltage (12V or 24V) and choose suitable fittings and pipes to avoid leaks and malfunctions.

How to Choose the Right Marine Water Pressure System for Your Boat

* **Flow Rate:** Consider the number of taps and showers you'll use simultaneously. A flow rate of 10-15 l/min is sufficient for a small boat with a single outlet, while larger boats with multiple bathrooms may require a system of 20-30 l/min.
* **Pressure:** The ideal pressure is 2-3 bar. Too low pressure will make showering difficult, while too high pressure could damage pipes and fittings.
* **Noise Level:** Quiet systems are more comfortable, especially if installed near cabins.
* **Dimensions:** Ensure the system fits in the available space on board. Also, consider ease of access for maintenance.
* **Consumption:** An efficient system will consume less energy and preserve battery life.

The Officina Basile Tip

* Replace the system's filter annually to prevent impurities and sediment from damaging the pump.
* Use an accumulator tank to reduce the on/off cycles of the pump and prolong its lifespan.
* Periodically check the air pressure in the accumulator tank.
* If the boat is not in use for an extended period, drain the system and tank to prevent the formation of algae and bacteria.

FAQ - Frequently Asked Questions

Which marine water pressure system do I need for the external shower of my sailboat?

For an external shower, a system with a flow rate of at least 8-10 l/min and a pressure of 2-3 bar is sufficient. Make sure it is compatible with your boat's voltage (12V or 24V) and has an adjustable pressure switch to avoid pressure fluctuations.

How can I reduce the noise of the marine water pressure system?

Use flexible rubber hoses to connect the system to the plumbing. Install an accumulator tank to reduce on/off cycles. Mount the system on anti-vibration mounts. Alternatively, choose a model specifically designed to be quiet.

What happens if the marine water pressure system turns on and off continuously?

There may be a leak in the plumbing, or the air pressure in the accumulator tank is too low. Check for drips from taps, fittings, or pipes. Check and adjust the air pressure in the accumulator tank according to the manufacturer's instructions.

Can I use the marine water pressure system to power a watermaker?

No, marine water pressure systems are not designed to provide the constant and high pressure required by a watermaker. To power a watermaker, you need to use a specific high-pressure pump.
