I been thinking - and I know that is dangerous. :RWe usually break camp in FL earlier than a normal show bird and it was freezing adz cold when we got back to IL this winter. I Winterized with the pink stuff in FL but since I left my head buried in the sand down there Murpy got me.So now I am repairing a cracked 90 degree elbow in the basement and have the black flow prevention thingey on order.I am thinking that the reason that the mfg installed an outside shower on my trailer was for the purpose of winterizing the black tank flush line. It seems to me that rigging a tube/hose that could be used for connecting the shower faucet to the tank flusher (which are located next to each other) would take care of my issue.What do you think of that brain storm? Feasible? :h

Feasible, and a good idea.I just winterize our black tank flusher with a good shot of compressed air.

That's what I did. After getting the antifreeze thru the shower head changed nozzles and hooked up to black tank flush.

I think a simple blow of the line would work just fine, don't use the "Pink Stuff" just drain and blow the lines. The flusher line could be blown with a had pump.

I must be lucky because I have never winterized the black tank flusher and have never had a problem. Dumb luck I guess.

another advantage of my old fashioned tank flusher, anti backflow valve on hose, whole thing just drains out.bumpy

I don't think that is the actual design reason for the outside shower, but I do use it to winterize the black tank flush. But then I use it for a number of other things also.

I have never winterized a black tank flusher...they seem to self purge. Guess I'll add it to the list! Thanks

This is what I have been doing for years... just a quick shot of air... just enough to MOVE any standing water in the line or path to the black tank...

I have just been blowing my BTF out with air. I also have an extra 12v pump that I use to add water to my fresh tank, when no water hookup is available, pump pink into the city hookup for winterizing, and could be used to run pink into the BTF.

I think your outside shower would work, with the right fitting, to run pink through the BTF. Let us know your fitting hookup idea.

I also have never worried about winterizing the black flush line and never had a problem. After reading replies here I probably will give it a shot of air this coming fall if I remember, but that's purely overkill. I wouldn't worry about it.
