Don't mix the water filter with the black water flush system....they are not related!

Flushing out 8289ws tanks

One of the first things that I bought was a clear plastic elbow for my sewer hose. That way when I flush my black water tank using that outside hose connection I can actually see when nothing but clear water is coming out. I will sometimes close the black water valve with the flush hose running momentarily to get just a little water back in the tank and then reopen. That helps me know that I have most everything out of the black water tank. Disclaimer......DO NOT CLOSE THAT VALVE WITH THE WATER RUNNING AND LET IT RUN VERY LONG.

I would love to hear other folks opinions of doing this. It is just a way I figured out to get a little more of the crud out of the tank. Most of the time after flushing for a bit the culprit seems to be left over paper.

I do the same, I don't have a clear elbow, just unhook and check the outflow when it slows down.

Clear elbow,

One of the best and least expensive accessories I have bought.

I also added a valve ahead of the elbow for insurance.

Our black tank got plugged with who knows what. Anyway, after lots of failed attempts to get it to drain, I closed the dump valve and used the clean out input to fill the tank. The wife was inside watching and yelled when water began to back up into the toilet. It took many minutes for it to fill. Then, after checking to be 100% sure all sewer hose connections were tight, I opened the drain valve. Whatever the problem had been got washed out the drain valve. It was an unnerving experience but I was desperate. It was the only way I could think of to get it flushed out.

Actually, other than letting it back up into the toilet that is the way the black tank is supposed to be cleaned out. Should fill till full indicator (light) annunciates or water reaches to the bottom of toilet input to tank and then open dump valve. Will never have a light issue and the tank will not require any of those cleanout procedures. The tank will not fill up immediately, mine takes about 20 minutes. There are many who think this is ridiculous but just google for black tank cleanout procedures. There are also many urban legends of overflows and such. Just don't walk away, as you normally wouldn't anyway, while dumping.

I have not tried that bubbles but certainly has merit.
