RV manufacturers can get fairly tricky. On the Airstream trailers, you have to be careful as there is a water inlet for drinking water and another water inlet for flushing your black water tank. It would not be a good idea to confuse the two.
The Fullway termination valve will be exactly where your black water dump valve is located. The two are the same. Many Airstream owners are upset about this change of wording as they have not been told that the two labels direct them to the same part.
No matter if it is an Airstream or Keystone or other RV, the Fullway valve should be the blade valve you open every time you go and dump your black water tank. You want to make sure that the valve is open all the way before starting to dump. This valve should be underneath your trailer near your drain outlets.
The first step in this process is to make sure you have the right drain hose and it is the one that securely fits your drain outlets. That should be a given. Next, you need to find where your drain valves ate located and they are near your fresh water is hooked up.
The third step will be to get your RV in an uphill position so that the tanks will drain properly. Then hook up your drain hose. Once you have the drain hose in place and the other end is inside the dump station’s tank opening, you can now open the Fullway termination valve.
That valve is your black water drain valve that should be lower to the ground than the fresh water hookups. Use your flush system to thoroughly clean your black water tank and once you have finished flushing you need to close that valve again.
Before you unhook your drain hose, open your gray water tank’s drain valve and dump it. This will clean out the drain connection and the drain hose saving you some work. After both tanks have been drained, unhook the hose, make sure all valves are closed and put the hose away till you need it again.
The issues that you may encounter may be different than the ones described here. The reason for saying that is different RV manufacturers make different flush systems. But these issues may help you find your problem.

If the problem is the nozzle, then you may have a difficult time reaching it as it is inside the tank and you have to cut through some plastic after crawling under your RV. Once you reach it, you have to remove, clean, and return it.
Understanding terminology may be easy for some people but that is only if they understand the language. It is not so easy when RV companies use terms then never explain them in the owner’s manual.
