Fresh water pumps: mastering the onboard water system

Fresh water is a precious resource at sea. A reliable and efficient plumbing system is essential for comfort and hygiene on board. At Skysat, we rigorously select fresh water pumps for their robustness, energy efficiency, and quiet operation. Discover our range and the factors to consider for optimal installation.

choose the pump that's right for your boat

The choice of freshwater pump depends on the size of your boat, the number of water outlets, and your water consumption habits. An oversized pump will waste energy, while an undersized pump may not provide sufficient flow. Here are some types of pumps to consider:

• Triplex diaphragm pumps: Renowned for their reliability and ability to handle low flow rates with constant pressure. Ideal for small and medium-sized sailboats.
• Automatic pressure switch pumps: These activate on demand when the circuit pressure drops. They offer a good compromise between performance and simplicity.
• Variable displacement pumps: Adjust their speed according to demand, reducing energy consumption and noise. Suitable for larger installations.
• Water boosters: Increase the pressure of the mains water, particularly useful in ports where the pressure is low.

optimize your hydraulic system

Proper installation is essential to ensure the longevity and efficiency of your freshwater system. It's important to choose high-quality pipes, install a filter to protect the pump from impurities, and include an expansion tank to stabilize the pressure. Also consider soundproofing to minimize noise.

• PEX multilayer pipes: Offer excellent resistance to pressure and temperature, while being easy to install.
• Water filters: Protect the pump from particles and extend its lifespan. Choose models with replaceable cartridges.
• Expansion vessels: Stabilize pressure and reduce pump start/stop cycles, thus improving efficiency and reducing noise.
• Silent block kits: Reduce pump vibration and noise by decoupling it from the boat structure.

maintenance and winterizing

Regular maintenance is essential to keep your freshwater system in perfect working order. It's important to clean the filter regularly, check the condition of the pipes, and winterize the system properly to prevent freezing and bacterial growth.

• Specific cleaning products: Use products suitable for drinking water systems to eliminate deposits and bacteria.
• Winterizing kits: Allow the system to be completely drained and a non-toxic antifreeze to be introduced to protect the pump and pipes from freezing.
• Regular descaling: Remove the limescale buildup in the pump and pipes to maintain optimal flow.
• Checking connections: Regularly check the tightness of fittings and clamps to prevent leaks.

💡 Skysat's advice

When choosing your pump, consider the power supply voltage (12V or 24V) and the presence of a pressure controller. A pressure controller maintains constant pressure even with flow rate variations, thus improving user comfort.
