Step 2: Find the Valves

 On our RV the valves are on the backside towards the rear, on most RVs I have noticed that it is hard to miss. Look under your Rv for a large pipe and some handles. Ours is easy to find and plainly labeled "Waste Water" for the sinks and shower (this is also known as the gray water) and "Sewage Water" (also known as the black water).
<p>Need help regarding draining black tank on a Dutchmen Aspen Trail travel trailer. It is not moveable. The sewer tank to dispose it into is about 40 feet away. It is also slightly elevated. Does the draining only work with the help of gravity, or is there an way to force the contents out, in spite of a slight elevation?</p><p>THANK YOU!</p>
I've heard if you are traveling and want to clean your tanks, dump some ice down the toilet and drive... Cleans up the tank nicely
Some RVs have a pump called a mascerating (spelling?) pump that is sort of like a high powered blender so that there are no solids in the tank at all. It might be a good idea to have that special pump. I believe that some rigs also use that pump to force the waste to dump.
I know this is an old thread, but a mascerator fits on the drain of the tanks. It only &quot;blends&quot; the stuff as you drain the tank. It doesn't do anything to the stuff going into the tank.
this seems like a no brainer but i had a hell of a time draining my tank. definately gonna make myself a wand like yours, as well as use the laundry detergent, thanks!
Please leave any improvement ideas, suggestions for deodorizers, or just general knowledge of the subject. I am not an expert and always appreciate learning a better way to achieve my goals.
