Boat pressure pumps: pressurized water on board
The pressure pump is the pump that pressurizes the boat's fresh water system: it starts automatically when you open a tap or the shower and stops when you close it, thanks to the pressure switch. In this category you will find pressure pumps and components from brands such as Gianneschi and Jabsco.
What to consider when choosing
- Flow rate in liters per minute, based on the number of taps and showers.
- Voltage of the onboard system (12 V, 24 V or 230 V).
- Water tank: reduces frequent pump starts and makes the flow more regular.
- Pressure switch: adjusts the start and stop pressures and is available as a replacement part.
Frequently asked questions about pressure pumps
Why does the pressure pump start and stop continuously?
The most common causes are a small leak in the system, an empty expansion tank, or a misadjusted pressure switch. It is advisable to check them in this order.
Is the expansion tank necessary?
It is not mandatory, but it reduces the number of pump starts, extends its life, and makes the flow more consistent.
Can the pressure switch be adjusted?
Yes, many pressure switches have an adjustment screw for the start and stop pressures; if it is faulty, it is replaced as a spare part.
