Watermaker Installation & Repair
Professional Watermaker Installation
While onboard freshwater tanks remain the traditional source of supply, their capacity often limits autonomy and convenience. A watermaker on yacht expands this capability by providing a continuous supply of potable water through reverse osmosis desalination. Because these systems operate at high pressures and require precise integration into existing plumbing and electrical systems, professional installation is essential. Our certified yacht technicians handle installation, commissioning, and ongoing service for watermakers of all sizes and configurations.
Benefits of Installing a Watermaker
Watermakers complement existing freshwater systems by converting seawater into clean, drinkable water using semi-permeable membranes. This process removes salts, silt, bacteria, and other contaminants, making it a reliable and safe source of water onboard. The advantages include:
- Reduced reliance on limited freshwater tank capacity, lowering vessel weight and increasing efficiency
- Extended cruising range by eliminating the need for frequent refills in port
- Significant cost savings by reducing or eliminating freshwater resupply fees abroad
- Emergency water production in the event of tank contamination or leaks
We install a wide range of systems, from compact DC-powered watermakers ideal for sailboats to engine-driven and 120V/230V AC watermakers designed for higher production on larger yachts. Each system is selected and configured according to the vessel’s size, energy profile, and cruising plans.
Consistent Watermaker Maintenance & Efficient Repairs
Watermakers are intricate systems consisting of pre-filters, booster pumps, high-pressure pumps, membranes, and post-treatment stages. Because they operate at pressures often exceeding 800 psi (55 bar), regular service is critical to maintain safety and efficiency. Our maintenance programs include routine freshwater flushing, filter replacement, biocide rinses, and carbon block checks to keep the membranes free from fouling and biological growth.
Performance monitoring is achieved by measuring TDS (Total Dissolved Solids) levels, permeate flow rates, and rejection percentages, ensuring the produced water consistently meets drinking water standards. In addition, we inspect high-pressure seals, hoses, valves, and fittings for wear and potential leaks. Without proper care, common issues such as membrane scaling, air locks, or pump cavitation can occur, reducing efficiency and risking system failure.
When repairs are required, our experienced technicians diagnose and resolve issues quickly, from membrane replacements and pump overhauls to electronic control panel servicing. We partner with leading watermaker manufacturers and carry OEM spare parts, ensuring that every repair restores the system to peak operating condition. With our expertise, your yacht’s watermaker remains a dependable and efficient source of fresh water at sea.
Advanced Watermaker Options for High-End Yachts
UV Sterilization & Remineralization: For superior water quality, we integrate UV sterilization units to eliminate any remaining bacteria and remineralization cartridges to balance pH and restore essential minerals, producing water comparable to premium bottled quality.
Automated Flush & Control Systems: We install PLC-controlled automatic flush cycles and remote monitoring panels that manage rinsing, chemical preservation, and flow regulation with minimal crew intervention. Systems can also be equipped with app-based monitoring, allowing owners and engineers to check water quality and status remotely.
Energy Recovery Devices (ERDs): To reduce power consumption, we offer systems with integrated energy recovery technology, lowering electrical demand by up to 80% and making them ideal for yachts with limited generator runtime or hybrid-electric propulsion setups.
Redundancy & High-Capacity Systems: For superyachts and long-range cruisers, we design installations with dual-membrane redundancy and modular pump systems, ensuring uninterrupted operation even in case of partial failure. Production rates can be scaled from 30 to over 1,000 liters per hour, depending on vessel requirements.
These advanced options make our watermaker installations not only functional but also cutting-edge in terms of efficiency, convenience, and water quality—perfectly suited for the demands of modern high-performance and luxury yachts.
