Welcome! If you’re a first-timer, learning to care for your black and gray tanks might seem overwhelming, but don’t worry—we’ve got you covered with simple, straightforward tips. With the right tools and knowledge, you’ll keep your plumbing system running smoothly and odor-free.
Before you hit the road, make sure you have these essentials:
Pre-Charge the Tank
Before use, add a few gallons of water to your black tank using your rinser or toilet. This helps waste disperse properly and prevents it from drying out and causing clogs.
Use Poopit Treatment
Fill the toilet bowl with about 1 gallon of water (a full bowl), then pour in the recommended amount of Poopit liquid treatment. Immediately flush it into the black tank.
In hot climates or if your tank holds more than 40 gallons, repeat the process—adding an additional 2 gallons of water for improved performance.
For best results, follow the dosing instructions on the Poopit bottle. Adding more water (not more product) helps maximize effectiveness.
Keep the Black Valve Closed
Always keep your black tank valve closed until the tank is at least two-thirds full. This allows waste to accumulate and ensures a strong, complete flush that avoids buildup.
Rinse After Dumping
After emptying your black tank, rinse thoroughly using your RV’s built-in tank sprayer or a tank cleaning wand.
Avoid Long-Sitting Odors
If your RV has been sitting unused and odors develop, fill the tank with water, add ½ cup of baking soda, and let it soak for a few days. Afterward, dump and treat with Poopit for a fresh reset.
Toilet Paper Tips
Poopit is compatible with all septic-safe toilet papers. To test yours, place a square in water—it should break down within 5 minutes.
When to Treat
You don’t need to treat your gray tank after every dump. If odors occur, pour 2–3 ounces of Poopit liquid into a bucket of water, then pour the mixture down the sink drain and let it sit overnight to neutralize smells and clean buildup.
Routine Treatment
For regular maintenance, treat your gray tank every third dump. Fill the sink with about 1 gallon of water, add the recommended amount of Poopit, and immediately drain it into the system.
Dealing with Grease
If you’re dealing with greasy residue, add 2–3 ounces of Blue Dawn dish soap directly to the tank to help break it down.
Leave the Valve Open?
You can leave the gray tank valve open during use, but be sure to close it a few hours before dumping. This allows gray water to accumulate, which can be used to rinse your sewer hose after dumping the black tank.
