Ok I am tired of dragging the hose in through the trailer to flush my black tank. The only one I know of is the CAMCO Tornado. I understand to use good 3m Silicone and also clean and prep the area well. I was thinking of a minor change right off the bat and that was instead of using the hose that it comes with upgrading that to 1/2 PVC and then just a small piece of heavier hose to join the two. For those of you that have done this or seen one of these is this over kill?If you have not seen the product here it is CAMCO Tornado

How will you winterize it so that the PVC doesn't break? I haven't seen anyone address this issue. Maybe it is not an issue but it seems to me that the low point in the line would need a drain. I think PEX is less likely to break than PVC.

I installed a Quickie Flush in my Class C and it was one of the best Mods I have done, and pretty simple.I picked the Quickie Flush over the Tornado because of the high failure rate of the swivel part. A few of my friends had them fail and it leaves it useless in the tank.The only thing that I changed is where the hose connects up with the flusher I put a 90 Degree Elbow in it to reduce the strain on the hose and make it closer to the tank.It looks like this when finished, with a quick disconnect on the end.Don't get discouraged if it leaks at the hose connections at first they are sometimes hard to get tight. Tightened mine up and have had no leaks anywhere.Another suggestion is to make a test hole in a piece of wood or something and test fit the device to the hole. I found that the hole size suggested was much larger than needed.Good Luck.

Stay with the flex hose. It is a low pressure application. PVC will probley not do well in the long haul. The Tornado actually was rated highest of the leading 3 according to a thorough non biast youtube report I saw recently. I liked it so well I put one on my gray tank as well. A smart adition. HAPPY TRAILS

We had a Tornado and about half the spray holes clogged after a few years. I went to a Flush King. It doesn't spray the water like a Tornado. I put a typical water faucet inline in the outflow pipe near the pump so I can flush using tank or shore water. I have a 4' water hose between the faucet and Flush King.

I have come to the conclusion that while the black tank flusher's maybe better than nothing they are not very effective. A Flush King requires no permanent installation and is much more effective at clearing tanks

I have a tank sprayer and the Flush King. Flush King works better.

All the tanks I have seen have a "belly" but the absolute lowest point is the pipe with the bottom contoured towards it. No obstructions and no pooling. Assuming the dump site is level. The tank in the video is just a box with a pipe near the bottom causing an obstruction.

The bottom of a black tank has a belly to it. So it's not flat either. There will always be a "pool" of water in the middle, this where the "stuff" accumulates. Unless you are rinsing from the inside out, nothing else will clean it any better.

I have watched those videos several times and they are not entirely accurate. Look at your black tank and you will see the bottom of the tank funnels to the drain pipe leaving no restriction. For example, a few years ago I dropped a camera on a stick down there "eeww" and took a video, added 1 bag of ice and drove for an hour. Went from not so clean to very clean. One of his demos says that doesnt work, but it does.

I now use the flush king and it works well.

Thanks for the video. He touches on a concern of mine as I have 2 90 elbo's. I will have to look at the other CAMCO one as well.

Nice video but 2 issues strike me . The discharge of a real black tank is not totally flush with the bottom of the tank like the clear video tank. You do not have the luxury to locate the black tank sprayer in an optimum location.
In reality you only have a few places where you can access and install the sprayer. Most times it is not in an optimum location.
In the end the video does allow you to see how the various devices work however I'm not sure it accurately shows how effective the devices are.

You might change your mind after watching This Video at about 12:17, I will stick with my Quickie Flush,conclusion at the end of it is not so good for the Flush King.

Mine came with a BTF that I use when it is handy to do so. I can hear the spray, so it is probably helping to clean the tank. Most of the time I just dump a couple of 3 gal pails full down the stool, close the valve, put 3 more gallons in to keep tank wet, until next use.

If my BTF ever quit working, I don't think I would bother to replace it.

I also have the quikie flush. I would not use PVC to plumb it. The tank will flex and the line to it needs to flex with it.

The in tank rinsers will push out the "stuff" rather than the other types that will push it all back in!
