Step-by-Step Guide to Cleaning Your Travel Trailer Water Tank

Step 1: Prepare the Vehicle

Start by ensuring your travel trailer is parked on level ground and disconnected from any external water supplies. This prevents dirt or contaminants from entering your system during cleaning.

Step 2: Drain the Water Tank

  1. Locate the Drain Valve: Find the drain valve of your water tank, typically located underneath the trailer.
  2. Open the Valve: Use a wrench if needed to open the valve. Allow all the water to flow out completely.
  3. Flush the Tank: Once drained, use a hose to flush fresh water through the tank. This initial rinse helps remove loose debris.

Step 3: Cleaning Solution Preparation

Depending on your preference for using bleach or vinegar, prepare your cleaning solution accordingly:

  • For Bleach Solution:

    • Mix 1 cup of bleach with 5 gallons of water.
  • For Vinegar Solution:

    • Combine 1 cup of white vinegar with 5 gallons of water.

Step 4: Apply the Cleaning Solution

  1. Using a Funnel: Gently pour the prepared solution into the water tank using the funnel.
  2. Fill the Tank: Add fresh water until the tank is full, enabling the cleaning solution to circulate effectively.

Step 5: Agitate the Mixture

  1. Turn on the Water Pump: Activate the trailer’s water pump to allow the mixture to flow through the entire plumbing system.
  2. Open All Faucets: Run each faucet (kitchen, bathroom, and shower) until the cleaning solution emerges. This helps disinfect your plumbing.
  3. Let it Sit: Allow the cleaning solution to sit for at least 2-3 hours (or overnight), giving it time to eliminate bacteria and break down deposits.

Step 6: Flush the System

  1. Drain Again: After the waiting period, drain the tank again, similar to Step 2.
  2. Rinse Thoroughly: Refill the tank with fresh water and flush the system several times until there’s no residual smell of bleach or vinegar.

Step 7: Inspect and Maintain

  • Check for Sediment: Use a clean sponge or brush to scrub any visible stains or deposits on the tank’s sides.
  • Routine Check: It’s advisable to perform this cleaning protocol every six months to maintain fresh water quality.

Additional Tips for Water Tank Maintenance

  1. Regular Flushing: If the camper is unused for a while, it’s beneficial to drain and flush the tank periodically to prevent stagnation.
  2. Install a Filter: Consider adding a water filter to enhance water quality and prolong tank cleanliness.
  3. Use Non-Toxic Cleaners: Always opt for biodegradable and septic-safe cleaning agents to protect your tank and the environment.
  4. Winterization: Ensure your water system is properly winterized to prevent damage from freezing.

Common Mistakes to Avoid When Cleaning Your Water Tank

While cleaning might seem straightforward, certain missteps can lead to further issues:

  • Not Rinsing Thoroughly: Leaving behind cleaning agents can contaminate your fresh water supply.
  • Using Harsh Chemicals: Avoid using abrasive cleaners that can damage the tank’s surfaces.
  • Ignoring Regular Maintenance: Neglecting periodic checks leads to more significant problems down the line.
