“Your grey and black tank valves are very important if you plan to use water/shower and the toilet in your RV. This valve perfectly matched the old one that was on my RV. It bolted on perfectly with no leaks. Great product and great price, would highly recommend it for anyone who needs to replace their valve.” -Daniel C.

✅ Clean & Convenient Waste Management: Tired of dealing with messy hookups and separate valves for gray and black water? This dual waste valve connects both your gray water tank (typically from sinks and showers) and black water tank (from the toilet) into one sealed system. It allows for simultaneous draining through a single outlet—minimizing spillage, simplifying your routine, and keeping your campsite clean.

✅ Easy to Use: The valve includes two distinct, color-coded T-handles—gray for gray water and black for black water—making it easy to identify and operate the correct valve, even in low light. This prevents cross-contamination and eliminates guesswork, especially helpful for new RV owners.

✅ Fits Most RVs: Designed with a standard 3” hub for black water and a 1.5” hub for gray water, this valve fits most common RV waste systems used in campers, trailers, and motorhomes. It’s a great drop-in replacement or upgrade for your existing waste valve assembly—no custom parts or complicated tools required.

✅ Tough, Long-Lasting Materials: Constructed from high-strength ABS plastic, this valve is built to resist cracking, corrosion, and mild chemical exposure commonly found in RV wastewater. It’s made to endure outdoor conditions and frequent use—ideal for long trips or full-time RV living.

Q: Will this valve allow me to drain both tanks at the same time, or do I need to open them separately?
A: Yes, this valve is designed to allow simultaneous draining of both your gray and black water tanks. With both handles open, the waste flows through a combined outlet, making the process quicker and reducing the number of steps needed to empty your tanks.
Q: Is this valve easy to install myself, or will I need professional help?
A: Most RV owners with basic tools can install this valve themselves. It connects using standard hub fittings (3" for black water, 1.5" for gray water), and the bayonet cap provides a secure, tight seal. Just make sure to shut off your tanks and have proper support during installation to avoid spills.
