Winterizing Tank Rinser
I can't remember how I did it last year....or even IF I did it last year. But how does one get some anti-freeze into the tank rinser lines and valve? I have an idea of a gadget that I can rig up...

I also use the outside shower hose to pump antifreeze thru the black tank flush (rinser) lines. And I also removed my antisiphon/backflow preventer valve after it started leaking and simply connected the lines together. I use an external antisiphon valve now.
But the lines do not self drain. You can see in the picture below that the lines contain the pink stuff after winterizing. The other two lines are my shower faucet lines.
Of course YOURS do not drain...you removed the vacuum breaker.
With OEM vacuum breaker the lines drain because the vacuum breaker OPENS to atmosphere
