Tornado flush added to black waste tank...
While working on a different black tank issue, I decided to finally add a black tank flush system. My hope is that it will keep my sensors clean and accurate. It seems like most times when I dump my black waste tank the 1/3rd and 2/3rd sensors have been staying "on" and that forces me to get out the hose and wand, run it all through the window, down the toilet, etc to get it clean (what a pain). Hopefully this works...
I picked the Tornado tank flush system. You can find it here or on amazon...

In order to drill the hole in the rear of the tank (so it is blasting water towards the drain), I needed to remove the rear outer tire and the forward flap.
There is a template that comes with the system so it makes it easy to know exactly where to put all the holes.
Apply lots of silicon and fasten the unit to the tank...
I added an elbow to reduce hose strain.
I ran the hose to the drain valve area (seemed like a good place), ziptied it up and out of the way, and cut the hose to length.
Here's a modification I made to the Tornado system that should help me and hopefully others can take advantage. I noticed that the spray pattern was not ideal for my tank and sensor setup. The head of the device that is inserted into the black waste tank spins so it sprays water pretty good. Here is what it looked like out of the box...
I felt like it might not hit my sensors as much as I want to get them clean. So I took the smallest drill bit I have and added two more holes in just the right spot so that the water will hit the area it was missing. I tested it all (uninstalled) on my driveway and it created the pattern I was looking for. Here is what it looks like:
Total time to install was probably about an hour with much of that involving jacking up the RV, placing jacks (for safety) and removing the outer dually tire.
I'll let the silicon dry and then test it out.
If this works as I hope it does, it will be so nice keeping my tank clean after dumping and more importantly my sensors clean without ever having to bring a hose through the window and wand down the toilet again.
Happy Camping!

Update: I was doing another black tank project and accidentally broke the outside connection of the Tornado Flush. So I bought a new one. When I used the same silicon sealant it started having a small leak at the sealant connection. I tried a couple times (with water thankfully) and it kept leaking just a little. So I removed it, cleaned off the surfaces, and used Sikaflex-291 after some research. Here is the link:

Marine grade. Made for "below water line" connections. Zero leaks and I feel great it will stay that way. Good luck!
