Step-By-Step: How to Clean and Sanitize Your RV Water System

4/15/2026

Sanitizing your RV’s fresh water system is essential after storage, buying a used RV, or when water smells or tastes off. The process cleans the tank, lines, and fixtures to ensure safe, fresh water.

Basic Steps

  1. Drain the fresh water tank and lines

  2. Add diluted bleach (¼ cup per 15 gallons)

  3. Fill tank with clean water

  4. Run solution through all faucets and fixtures

  5. Let sit for several hours or overnight

  6. Drain and flush system until bleach smell is gone

Key Tips

  • Remove or bypass water filters first

  • Don’t forget outside showers and extra fixtures

  • Use unscented household bleach only

  • Flush thoroughly—this is where most people cut corners

When to Sanitize

  • After long storage

  • After buying a used RV

  • If water smells or tastes bad

  • At the start of the camping season

Bottom Line

Sanitizing your RV water system is a simple but important maintenance step that keeps your water clean, safe, and fresh.
