Winterizing the Black Tank Flush

Here is my cheap solution to winterizing the black tank flush, if you have an outside shower.

Go to Lowes and buy a 1/2" MIP to 3/4" Male garden hose adaptor (Watts # A-663). Remove the shower head from the hose and screw in the adaptor. The adaptor then screws into the black tank flush. Turn on the shower spigot and let the pink stuff flow.
Cost $3.42.

Nice suggestion, I dont have an outside shower.

I wish i had pumped a bit in mine. I blew out the two I have with air, hope it doesnt get to cold in SC. I had a plastic pump but didnt have it with me. I will put some in next year, hopefully wont have to repair anything. If I go down for a couple days in November I will put some in the lines.

That's a great idea!

Also good for rinsing out the tank if you ever got in a situation where there is no city water hose to flush with. And pink stuff could be poured into the black tank flush with a funnel and a short lenth of water hose like comes with an outside water filter if you have no outside shower.

Great Idea ! Even if you had to add a piece of hose it would work great!

your flush is positioned much different from ours
ours is up on the sidewall and has a self drain and a vacum break inside, i dondt think i could put pink in it with it draining out.

cool idea though for flushing the puppy, thanks
