Understanding Your RV's Grey Tank

Your RV's grey tank collects wastewater from your sinks and shower. Unlike the black tank (which holds toilet waste), the grey tank deals with "greywater," which is generally less problematic but still requires regular cleaning. Neglecting your grey tank can lead to unpleasant odors, clogs, and even costly repairs. This guide will walk you through the best practices for keeping it clean and functional.

Preventing Grey Tank Buildup: Proactive Measures

Prevention is key! By adopting these habits, you can significantly reduce the need for intensive cleaning:

Minimize Grease and Oil: Avoid pouring grease, oil, or other fats down your drains. These substances solidify and contribute to clogs. Use a strainer to catch food scraps.
Use a Hair Catcher: Hair is a major culprit in grey tank clogs. A simple hair catcher in your shower drain prevents hair from accumulating in the tank.
Rinse Thoroughly: After each use of your sinks and shower, rinse them thoroughly with plenty of water. This helps flush waste down into the tank and prevents buildup.
Regular Flushing: Even when not actively using your RV, periodically flush the grey tank with water. This keeps things flowing and prevents stagnation.

How to Clean Your RV Grey Tank: A Step-by-Step Guide

There are several ways to clean your grey tank, each with its own pros and cons.

Method 1: Using RV Tank Cleaning Products

Many effective RV tank cleaning products are available on the market. These typically contain enzymes and detergents designed to break down organic matter and eliminate odors.

Empty the Grey Tank: Completely empty your grey tank at a dump station.
Add Cleaning Solution: Follow the instructions on your chosen cleaning product. Generally, you'll add the solution to the tank and fill it partially with water.
Let it Soak: Allow the cleaning solution to soak for several hours, or even overnight, to effectively break down buildup.
Flush Thoroughly: After soaking, flush the tank with plenty of water. This is crucial for removing loosened debris and the cleaning solution itself.

Pro Tip: Consider using a tank rinsing attachment to maximize the cleaning and rinsing efficiency.

Method 2: The Baking Soda and Vinegar Method (For Mild Buildup)

This natural approach is effective for tackling mild buildup and odors.

Empty the Grey Tank: As above, start by completely emptying the grey tank.
Add Baking Soda: Sprinkle a generous amount of baking soda into the tank.
Add Vinegar: Pour white vinegar into the tank. The combination will create a fizzing reaction that helps loosen grime.
Let it Sit: Allow the mixture to sit for several hours before flushing thoroughly with water.

Method 3: Addressing Stubborn Clogs

If you encounter stubborn clogs, you may need more aggressive methods:

RV Tank Cleaning Products: Use a powerful RV tank cleaning product specifically designed for clogs. Follow the product instructions carefully.
Plumbing Snake: In severe cases, a plumbing snake may be necessary to break up and remove the blockage. Be cautious when using this method.
Professional Help: If you're uncomfortable tackling the clog yourself, contact an RV service professional.

Maintaining a Fresh-Smelling RV: Post-Cleaning Tips

Even after cleaning, maintaining a fresh-smelling RV is important. Consider these tips:

Proper Ventilation: Ensure adequate ventilation in your RV, especially after using the shower or sinks. Open windows and use fans to circulate air.
Regular Cleaning: Make regular grey tank cleaning part of your RV maintenance routine. The frequency depends on usage, but aim for at least every few trips.
Odor Eliminators: Use RV-specific odor eliminators to neutralize any lingering smells.

Troubleshooting Common Grey Tank Problems

Slow Drainage: This usually indicates a clog. Try using a cleaning solution or a plumbing snake.
Persistent Odors: Ensure thorough cleaning and proper ventilation. Consider using an odor eliminator.
Leaks: If you suspect a leak, contact an RV service professional immediately to prevent further damage.

By following these tips and maintaining a proactive approach, you can keep your RV's grey tank clean and prevent costly problems. Remember, regular cleaning and preventative measures are far easier than dealing with a major grey tank issue down the road!
