black tank rinser

Howdy all. I'm sitting here at a full hook up site in my new to me HitchHiker. This is my first outing in it. This one has the built in black tank rinser. My old one did not. My question is, how do you guys use your black tank rinser when at a full hook up site? I do have a separate hose I would use exclusively for the rinser, but there is only one spigot here and it is for potable water. What do the rest of you do? No sewer/dump available at home.

those generally are not caused by timer error. they are caused by hitting the snooze button, etc.

Yeah, I think they can all be classified as human error. 🙂

As long as all those great times outweigh that one bad time... 🙂

The whole point of my post about whatever timer you use was that nothing is foolproof. If you do something that has a chance to go wrong, and you do it often enough, the chances are good that something will go wrong.

There is a vacuum break on them (required), but I still use a separate hose (same one for washing things off outside).

Don't leave it hooked up, especially to a Y. If a kid comes by and turns it on, you are in for a mess. I was in a park where that happened to someone.

I flush it once a month or so if stationary, it helps keep the gauge sensors clean, and before leaving otherwise.

This setup works GREAT!!!

I leave my grey tank open but about once every month I close it a couple days before I dump the black tank so it has a chance to loosen anything on the bottom of the tank.

So lets say it's a black and grey flush day.

I open black and grey valves at the same time and turn on both valves on the "Y". I Have a clear 45 elbow at the RV's sewer connection then the sewer hose after that. I observe the water turn clear and close both tank valves leaving the water run for 6-8 minutes. SET THE TIMER ON YOUR PHONE !!!!!!!

Open both tank valves let run til clear, close and set timer, open til just the water is running thru clear from the hose. Now close the black valve. Let the water run for about one minute. Close both valves at "Y".

The black tank will easily go one week so I usually do the deed on Sundays.

The dropping the "BOBM" is not a bad idea I may do this also. MeAgain's method.





The only problem I have with that is using a timer. I tried that, run for 5 min, and thought it was great. Then I got one of the inline water meters. 5 min gave abt 15 gal most campgrounds. I like to at least half fill (20+ gal) after the first dump.


8 minutes @ 5 GPM is 40 gallons. But the fact is I only do the grey while doing the black and there will never be that amount of water. My black is 50G and grey is 75G.

Adjust as needed.


Measure it sometime. I'll bet you are getting nowhere close to 5 GPM most likely abt 3 with the restriction in the rinser.

a small cheap kitchen timer is available at walmart for a buck or two. very easy to use, don't need the precision of a stop watch. 😛

Whatever device you use keep it on your self! It's easy to get distracted. That's why I choose the timer on my phone with a LOUD setting.

I find after the tank has drained and the black rinse is still running, I fill the toilet to the rim and dump the contents, repeating 2-3 times. This seems to help break up and move the last bit of debris out of the tank.

There must be some form of stopwatch for your computer. I guess not all microwaves come with timers.

I have a Y fitting I install on the park faucet with a white hose to my fresh water connection and a green hose to my black tank flush. Each side of the Y has a shutoff valve. I leave the fresh water side valve open. Then I just open/close the flush side valve each time after I drain the black tank.


Same here, i use a Y so I can have both oses hooked up if I'm staying any length of time.
