Fresh Water Tank Blues? Empty It Right Every Time

Dealing with a freshwater tank in your RV, boat, or camper can be a mixed blessing. While it provides the convenience of readily available fresh water, neglecting proper maintenance can quickly turn this convenience into a costly and frustrating problem. Ignoring your fresh water tank can lead to everything from unpleasant odors to serious health risks. This comprehensive guide will walk you through the proper procedure for emptying your fresh water tank every time, minimizing the chances of encountering those dreaded "freshwater tank blues."

Why Empty Your Fresh Water Tank Regularly?

Regularly emptying and cleaning your fresh water tank is crucial for several reasons:

• Preventing Bacterial Growth: Stagnant water is a breeding ground for bacteria and other microorganisms. These can lead to foul odors, murky water, and, more importantly, potential health problems.
• Minimizing Mineral Buildup: Hard water leaves behind mineral deposits that can clog pipes, reduce water flow, and even damage your water heater.
• Avoiding Algae Growth: Sunlight penetrating through the tank walls can encourage algae growth, further contaminating the water and creating unpleasant smells.
• Extending the Lifespan of Your Tank: Regular cleaning helps prevent corrosion and damage to the tank itself, extending its lifespan and saving you money in the long run.

How to Empty Your Fresh Water Tank: A Step-by-Step Guide

The process might vary slightly depending on your specific RV or boat, but the general principles remain the same.

1. Locate Your Tank Valves: Find the low-point drain valve(s) for your freshwater tank. This is usually located at the lowest point of the tank, often near the bottom exterior of your RV or boat. You'll also need to locate your city water hook-up.

2. Disconnect from City Water: Before you begin, ensure you're disconnected from any city water source. This prevents backflow contamination.

3. Open the Drain Valve(s): Carefully open the drain valve(s) to allow the water to flow out. This might require a wrench or handle depending on your setup. Be prepared for some initial gushing, so position yourself accordingly and be aware of any potential splashing.

4. Flush the Tank: Once most of the water has drained, consider flushing the tank with clean water. This helps remove any lingering sediment or debris. You can achieve this by filling the tank partially, letting it sit for a short period (15-30 minutes) and then draining it again. Repeat as needed.

5. Clean the Tank (if necessary): For a thorough cleaning, you may need to use a tank cleaning solution designed specifically for RV or boat freshwater tanks. Follow the product instructions carefully, and be sure to rinse the tank thoroughly afterward to remove any residual cleaning chemicals.

6. Close the Drain Valve(s): Once the tank is empty and clean, tightly close all drain valves to prevent leakage.

7. Air Out the Tank: Leave the tank open to air out completely, allowing it to dry. This helps prevent the growth of mold and mildew.

How Often Should I Empty My Fresh Water Tank?

The frequency of emptying your fresh water tank depends on several factors, including how often you use it and the climate. As a general rule of thumb, aim to empty and clean your tank:

• After each trip: This is especially important if you've been using the tank for several days.
• Every 2-3 weeks: Even if you're not actively using the tank, it's a good practice to empty and clean it every few weeks to prevent stagnation and buildup.
• Before long-term storage: Before storing your RV or boat for an extended period, thoroughly empty, clean, and dry the tank to prevent damage and bacterial growth.

What if I Smell a Foul Odor Coming from My Fresh Water Tank?

A foul odor often indicates the presence of bacteria or algae. Thoroughly cleaning the tank as described above should eliminate the odor. If the smell persists, consider using a tank cleaning solution specifically designed to tackle odors. If the problem continues despite cleaning, consult a professional for further assistance.

What if My Fresh Water Tank Won't Drain Completely?

If your freshwater tank won't drain completely, there might be a clog in the drain line or a problem with the valve itself. Check for any obstructions in the drain line. If the problem persists, you may need to seek professional help.

Can I Use Bleach to Clean My Fresh Water Tank?

While bleach can kill bacteria, it’s crucial to use it sparingly and to thoroughly rinse the tank afterward. Excessive bleach can damage the tank and leave behind a lingering chemical smell. It is generally recommended to use specialized RV tank cleaning solutions instead.

By following these guidelines, you can significantly reduce the likelihood of experiencing frustrating freshwater tank issues and maintain clean, safe water for your adventures. Remember, preventative maintenance is key to enjoying the conveniences of your freshwater tank without the headaches.
