Our first ever weekend in a TT was this past weekend we had partial hookups. I read and studied and was confident as we went to the dump site. I put together a brand new Rhino Flex Sewer kit from Walmart but for some reason, the Rhino Flex kit would not hold onto the four notches on the dump pipe of the RV. I slipped the four notches into the four baynet fittings and twisted it, but it wouldn't hold onto the notches as the liquid "surged" while emptying. It sealed and stayed that way if I held it; but it didn't seem to want to stay connected if I dind't keep two fingers onto it. I had the pipe running straight (no curves, dips or bends) from the TT to the dump site.

Is this common or is there some secret or trick this new guy needs to learn?

The 2-4 nibs should just fit into the notches on the Rhino Flex attachment and a twist should secure it well. Is the hose not being able to stay attached? Are there nibs missing, or on the hose, is one of the bayonet "claws" broken?

Strange..... Mine holds tight to the point that it was a struggle the one time I tried to disconnect it

The problem is the claws weren't holding well onto the TT hookup. None of them appeared broken, they just didn't really grab and hold when I twisted it on.

Check the bayonet studs, I bought one and now it is useless, the ears are to small and deform when you try to secure them when you twist them together.

The other problem that I encountered, was that when I tried to lock them, both would twist and the bayonet never latched. I will not purchase another one, going back to my blue hose and fitings.

Hope it helps

If the Rhino hoses clicks in place easily then look to see if the hose is missing its gasket. The gasket provides the positive seal AND it's thickness usually is enough to require a bit of hand strength to turn the hose fitting so that it clicks in place. The hose fitting should not lock on "super" easy.

Well said! My thought was that the gasket might not be seated completely into the fitting thus not allowing the full twist. I've had mine for 2 years and haven't had any problems~

The CLICK does the trick.

Are you twisting the fitting far enough to engage the detents so it CLICKS? As mentioned above, if no click the gasket could be missing.

I've got quite a few different brands of fittings, and I have seen some variation in how tight they fit. Some better than others. Anyway, I suggest you get a clear plastic 45° elbow to attach to the outlet, and then connect your Rhino to that. Then you can view and monitor the flow. I found the elbow to be a very good fit on the outlet. The possibility of the seal missing is an excellent point as well.

X2. But you still need the gaskets.
