Today we're going to be taking a look at the Valterra Gray Water Drain Adapter for RVs. What you'd do is you would install this on the valve for your gray water sewer tank, and then you can drain that tank by using a 0.5 inch or 5/8 inch diameter waste water hose. Instead of using your typical or standard 3 inch diameter sewer hose, you can use a 5/8 inch or 0.5 inch diameter waste water hose. This will attach to your Bayonet style sewer fitting. It's going to have an outer diameter, from this point here to this point here, of 3.5 inches, so it is designed for your standard fitting. At this point here, it will accept your standard 3/4 inch garden hose connection. You put your garden hose in there.
You got the threaded connector there. You thread that on for a nice, tight, secure fit. It's also going to include the plug so when it's not being used, you can keep that shut. That's held on there with a tether so you don't ever have to worry about misplacing that or losing that. It's also got a nice thumb grip design right here, so that way you can easily install it or remove this from the valve.
It's a nice durable construction. It's going to be black in color. That's going to do it for today's look at the Valterra Gray Water Drain Adapter for RVs.

The fittings have worked great. The one thing I find challenging with other products like this if finding the correct replacement gaskets. Your fittings and replacement parts are the exception.
Do you have a question about this RV Sewer Hose Fitting?

Still working like new, great to have on both grey and black water. You can check and make sure no leaks before popping the big cap
