Having clean water in your RV is very important. We use water for drinking, cooking, and washing. Clean water keeps us healthy. Dirty water can make us sick. That’s why we need to sanitize the RV fresh water tank. This keeps the water safe and clean.
Why Sanitize the Tank?
Over time, the tank can get dirty. Bacteria and algae can grow inside. These can make the water unsafe to drink. Sanitizing kills the bacteria and algae. It keeps the tank clean. It also makes sure the water is fresh.

Before you start, gather these items:
- White vinegar or bleach
- Clean water

Steps to Sanitize the Tank
1. Drain The Tank
First, drain all water from the tank. Open the drain valve. Let all the water flow out. Use a bucket to catch the water if needed.

Next, mix your cleaning solution. Use one cup of bleach or vinegar for every 15 gallons of water. Pour the bleach or vinegar into the measuring cup. Add it to a bucket of clean water.
3. Pour The Solution Into The Tank

4. Fill The Tank With Water
