Maintaining your RV's fresh water tank is crucial for a safe and enjoyable camping experience. Knowing how to properly empty it is essential for preventing bacterial growth, extending the lifespan of your tank, and preparing for winter storage. This comprehensive guide will walk you through the process, addressing common questions and concerns.
What's the Best Way to Empty an RV Fresh Water Tank?
The most effective way to empty your RV's fresh water tank involves a combination of gravity and a low-point drain. Here's a step-by-step guide:
-
Locate Your Low-Point Drains: These are typically located under your RV, near the plumbing system. They allow you to drain water from the low points of your plumbing system, ensuring complete drainage.
-
Open the Low-Point Drains: Open the low-point drain valve(s) specifically designated for the fresh water tank. This usually involves turning a valve or removing a plug. You might need a wrench or pliers for some setups.
-
Open the Fresh Water Tank Drain Valve: This valve is usually located near the bottom exterior of your fresh water tank. Open it fully to allow the water to drain.
-
Monitor the Drainage: Observe the drainage process. It may take some time, especially if your tank is large or the drain lines are somewhat clogged.
-
Check for Complete Drainage: Once the water stops draining from both the low-point drains and the tank drain, you can check if there's any remaining water using the low-point drain valves. If you still see water coming out, let it drain completely.
-
Close the Valves: Once the drainage is complete, close both the low-point drain valve(s) and the fresh water tank drain valve securely.
How Often Should I Empty My RV Fresh Water Tank?
The frequency of emptying your RV fresh water tank depends on several factors:
- Usage: If you frequently use the water, you should empty and refill the tank more often.
- Climate: In warmer climates, bacterial growth is more likely, necessitating more frequent emptying.
- Storage: Before long-term storage, especially during winter, it's essential to completely empty and sanitize the tank.
As a general guideline, emptying your tank every 3-7 days is recommended, especially if it's been used.
How Do I Sanitize My RV Fresh Water Tank After Emptying?
Sanitizing your fresh water tank is a crucial step in preventing bacterial growth and ensuring safe drinking water. After emptying, follow these steps:
-
Flush with Water: Run clean water through the tank to remove any lingering debris.
-
Add Sanitizer: Use an RV-specific water tank sanitizer. Follow the manufacturer's instructions carefully regarding the amount of sanitizer to use based on your tank size.
-
Fill and Swish: Fill the tank with clean water and let the sanitizer circulate for the recommended time (usually several hours). Swirling the water around using the water pump helps ensure proper distribution of the sanitizer.
-
Drain and Rinse: Drain the tank and then flush thoroughly with clean water to remove all traces of the sanitizer before refilling with fresh water.
-
Test Water: Before consuming water from the tank again, test it to ensure the sanitizer has been removed and the water is safe to drink.
What if My RV Fresh Water Tank Won't Drain Completely?
If your RV fresh water tank isn't draining properly, several issues could be the cause:
- Clogged Drain Lines: Sediment buildup or other debris can clog the drain lines. You may need to flush them out using a high-pressure water hose or a specialized drain cleaner.
- Frozen Pipes: In colder climates, frozen water can block the drain lines. Allow the pipes to thaw naturally or use a heating pad to carefully defrost them. Never use a torch or open flame near your RV's plumbing system.
- Faulty Valve: The drain valve itself might be malfunctioning. You may need to replace or repair it.
- Kinks in the Drain Hose: Examine the drain hose for any kinks that could be restricting water flow.
If you are unable to resolve the issue yourself, consult a qualified RV technician.
Can I Use Bleach to Sanitize My RV Fresh Water Tank?
While bleach is a common disinfectant, it's generally not recommended for sanitizing RV fresh water tanks. Bleach can leave behind a lingering chlorine smell and taste, and improper dilution can damage the tank's interior. Use only RV-specific water tank sanitizers.
By following these steps and addressing potential problems, you can keep your RV's fresh water tank clean, safe, and functioning properly for many years to come. Remember to consult your RV's owner's manual for specific instructions relating to your model.
