How we empty our RV waste tanks at a dump station

I just ran a long wire from the valve handle to the drivers seat. It's easy to drain the black tank while rolling down the interstate.
And, it saves time. No more waiting in line at the dump station. :B

And you are watering and fertilizing the roadside landscaping. Helping the road dept. How thoughtful!

If everything goes right there is no waste outside the hose and plumbing, and I never touch the inside of the hose or plumbing. So no contaminated gloves.

My hose drips when I disconnect it and I don't know what the guy before me did. I assume everything at the dump site has poop on it and I don't want it on my hands. I'll stick with the gloves.

Now that's an idea! I could do so many more activities if I didn't need to stop to dump the tanks;)

Now why didn't "I" think of that! Great idea! :B

That door was open before I started, so no they didn't:B But it is good to note that it's best to open all doors before you get started if you're going in and out.

If you have the black and the gray water discharge at the same outlet:



...you can back flush the gray water into the black tank and then dump the black tank, which will pull a LOT of stuff out.

In my photo "B" is the Black Tank valve.
C is the Gray tank valve.
A is 3rd valve (Flush King style) that has a clear section.

Steps:
1. Dump black tank first... completely till it stops (Open A and B). You can see it in the clear section of the valve.

2. Close Valve A. Leave B open and now open C. This will allow the gray water to back flush into the black tank.

3. Leave C open for about 10 seconds and then close it.

4. Now open A and B again. (This will redrain the black tank pulling a BUNCH more out.

5. Repeat a total of 3 times. After the third time, close the black tank and let the gray go, washing down the sewer hose.

Of course, this works best when the gray tank is full, or near full so there is plenty of water to swish backwards into the black tank.

This process works if you are dumping at the dump station, attached to a full hook-up, or using a sewer tote. I do this every dump, and it keep the black tank cleaned out. My trailer has the black tank flusher, and I also have the sleeve that goes into the toilet, and a wand that can go into the black tank via the toilet. But I have found the back-flush method does the best.

Actually, as a last step, put a little water in the black tank and drive onward. The little water in there will continue to slosh around, beating anything that might be stuck to the sensors, and pulverizing any solids that might have stuck. A few squirts of Dawn Dishwashing liquid will also help wash the inside of the tank too when sloshed around driving.
