Proper maintenance of your RV’s fresh water system is essential for ensuring clean and consistent water flow. This guide will help diagnose and fix common issues.

Initial Checks

  1. Check the Fresh Water Tank
    • Ensure the tank is full before troubleshooting.
    • Inspect for leaks or visible damage to the tank and hoses.
  2. Check the Water Pump
    • Turn the pump ON and listen for the motor running.
    • If silent, check power connections and the fuse.
    • If running but no water, move to the next steps.
  3. Inspect the Filters
    • Remove and clean pump filters to prevent clogs.

Common Issues & Solutions

  1. No Water at the Faucets
    • Check the pump operation: Ensure it’s running properly.
    • Inspect hose connections: Tighten any loose fittings.
    • Purge the system: Open all faucets to release trapped air.
  2. Low Water Pressure
    • Clogged filters: Clean or replace them.
    • Check for leaks: Look for dripping connections or wet spots.
    • Adjust the pump pressure regulator if applicable.
  3. Pump Runs Continuously
    • Look for leaks: A leak prevents the system from pressurizing.
    • Check the pressure switch: A faulty switch may cause the pump to stay on.
    • Purge air from the system: Open faucets until water flows steadily.
  4. Bad Odors or Taste in Water
    • Clean the tank: Use a mix of water and baking soda or an RV-safe cleaner.
    • Sanitize the system: Flush with a chlorine solution or designated sanitizer.
    • Replace old filters to remove bacteria or sediment buildup.

Preventive Maintenance

  • Regular Cleaning: Flush and sanitize the water system every few months.
  • Leak Inspections: Periodically check for drips and loose connections.
  • Winterization: Drain the system or use RV antifreeze in cold weather.
