I bought a Tornado for my black holding tank. I have a few questions for those of you have one before I cut the hole to install.
I tested the nozzle, hooked to a garden hose. The nozzle did not spin as a result of water flow. A large amount of the water came out of the seal area where the rotating head connects to the fixed pipe. I was not impressed with what I saw. The Tornado requires a minimum of 40 psi and no more than 60 psi. I have not measured my water pressure, but I have always considered to be a typical water pressure for a city water system. Has anyone tried the garden hose test before installing the thing in their tank?
The preferred position for installation is opposite the drain line. I know some of you have installed them in this position on a ROO. There is no room to drill or use a hole saw in that area because of the trailer frame (ROO23SS). How did any of you cut the holes.... with an exacto knife and a drimel tool?
I know many people are very happy with these devices. Right now I'm not impressed with what I have seen so far. Is this a defective Tornado?

try the tornado at a neighbors house. if it still doesn't work take it back and get another one. to make the hole in the tank use a drill with a hole saw. and a small drill bit for the screw holes. be sure to use a sealant to seal all around the tornado so you do not have any leaks.

I did the same thing you did, and mine did spin once out of 10 times. I don't have a roo, and there was no way I could get in as instructed. I would have to go thru the side.
I figured I got it on sale for $15.00. It was a close out at that store. Any thing was better then the hose down the john, or one of those back flushing devices. I also figured that any flow going in the right direction would be better then no flow at all. So I cut the hole on the side, and installed.
I was very impressed on the first use. I heard it spin for a few seconds then stop, but kept it running anyway. The crud that came out was impressive, not the crud impresses me. I now use it about every third dump. Some time it swirls, most of the time it doesn't but it does clean the tank. JM2Cents Bill

Do you have a water regulator? It goes inline with the water supply spigot before connecting to your city water inlet. Typical regulators for RVs regulate the water pressure to 45 PSI. Try one of these and see if you get the same results. If it continues to leak from the seal area, you have a defective unit.
As for cutting a hole in the tank, the optimal position is indeed the opposite side of the drain. However, you can install the Tornado in the side closest to the end of the tank as possible. It may not be 100% as effective, but it will work nevertheless. I did this on a Trail Cruiser that had the same issue as the ROO and never had any odor issues as a result.

well my tornado was installed by the dealer before delivery as part of the deal. It spins constantly every sing time I have used it. The only time it leaks is when I turn the water off, but I had asked on another forum and they said it was the normal pressure relief.. It was clean water coming out.

I measured my water pressure. It is greater than 60 psi. That may be the problem. I'll try it with a pressure reducer on the hose tormorrow. Maybe the high water pressure is the problem.

I would return the unit. Sounds like it is defective. Ours has rotated with every use. I installed using an angle drill and whole saw. It can be done on the opposite end of the drains with a little effort.

I ran into the same problem with not being able to fit my drill between the frame & the tank. The hole saw did fit though, so I used a racheting box-end wrench to turn the saw and used a scrap of 2x4 between the end of the saw and the frame to put pressure on the saw. This took some time but was a success in the end. For the screw holes, I used a right angle adapter in my drill. I remember reading that someone used a hot nail to peirce the tank in the screw hole locations.

I think I also read one time that someone heated a section of metal pipe of the same diameter with a plumber's torch and "pressed" it through the the tank which made the snug installation much easier.
I like the idea of the wrench/board. Good luck and happy mod'ing!

I used the ratchet-hole saw method. But I think there's probably plenty of room on the '08 and later Roos for a right angle drill adapter to get in there with the hole saw. The extra 6" width should have left a larger gap on the curb (starboard) side of the trailer. Anyone want to look under their's?
I heated a finishing nail and pressed it thru for the mounting screws.
I recommend marine below the waterline caulk. I just happened to have some from mounting my depth sounder, but it's not expensive and you don't need a caulking gun full of it.
There's a siphon breaker in the water line that mounts to the Tornado (or other rinser). It'll release clean, fresh water when you turn the water pressure off. There's an internal check valve in the Tornado. When the external parts of mine cracked and literally fell off there was no leakage from the tank.
