Maintaining Your Seawater Watermaker
Tips and Tricks for Longevity and Performance
For those who venture offshore, whether for work or pleasure, a reliable watermaker is essential. Watermakers from FCI Watermakers are known for their durability and quality, providing fresh water day after day. However, like any piece of marine equipment, they need proper care to perform at their best and last as long as possible. Here are some essential maintenance tips and tricks to keep your FCI Watermaker in optimal condition for years of seamless operation.
1. Regular Freshwater Flushes: Preventing Salt Buildup
After each trip or every few days of usage, it’s essential to flush your watermaker with fresh water. Saltwater residues can lead to mineral buildup and corrosion over time, compromising the system’s performance. Freshwater flushing not only helps prevent these issues but also plays a crucial role in membrane health and longevity. By keeping membranes wet, it prevents them from drying out and reduces the risk of seawater fouling. Automatic and Programmable Freshwater Flushes are available on all FCI Watermakers, making it easy to keep salt at bay and reduce manual maintenance.
2. Monitor and Replace Filters as Needed
Pre-filters are the first line of defense, capturing large particles and debris before they reach the delicate membranes. To avoid clogged membranes and maintain water quality, check your filters regularly and replace them as needed. It is recommended to replace your Pre-Filter when the system is operating at a Low Pressure Reading of 10 PSI or less. Keeping a few spare filters on board is always a good idea for quick replacements during extended trips.
3. Membranes are the heart of your watermaker, and they require special care. To maximize membrane life:
- Operation: It is important to operate the system in the parameters that are recommended by FCI Watermakers. In addition Watermakers like to be used, the more you use the system the longer the membranes will last. Additionally, watermakers perform best when used regularly—the more you use the system, the longer the membranes will last.
- Preserve When Not in Use: If you won’t be using your watermaker for a while, consider placing it in a preservation solution to prevent bacterial growth. This is especially important for seasonal boaters who may leave their vessels dormant for months.
4. Check for Leaks and Inspect Hoses
Regularly inspect the hoses, connectors, and fittings on your watermaker for leaks or signs of wear. Small leaks can lead to bigger problems if not addressed early. Ensuring hoses are intact and fittings are secure can save you from costly repairs down the line. If any hose or fitting looks worn, replace it promptly to avoid a failure mid-trip.
5. Maintain the Pump for Smooth Operation
The pump in your watermaker is another vital component. A failing pump can lead to poor water production or even damage other parts of the system. Make it a habit to check the pump pressure and listen for unusual sounds. Lubricating the pump (as directed by your user manual) and replacing seals or diaphragms as needed will help keep it running smoothly and quietly.
6. Use Quality Replacement Parts
When you need replacement parts, it may be tempting to use generic alternatives, but quality parts matter. FCI Watermakers designs their systems with high-quality, marine-grade materials that can withstand the harsh environment of the open sea. Using OEM (Original Equipment Manufacturer) parts ensures compatibility, maintains performance, and helps avoid issues down the line.
7. Keep an Eye on the Electrical System
Your watermaker’s electrical components also require attention. Inspect wiring for corrosion or fraying, as salt air can be tough on exposed metal. If your watermaker has an automatic control panel, make sure all settings are working correctly. Routine checks can prevent sudden power issues, ensuring your watermaker is always ready for action.
8. Follow a Maintenance Schedule
Creating and following a maintenance schedule is the best way to stay on top of watermaker care. Check your FCI Watermakers user manual for recommended service intervals, and consider keeping a log of when you perform each task. This can help you keep track of filter changes, membrane cleanings, and other maintenance essentials, ultimately extending the life of your equipment.
