pyramid

So I was wandering the web this morning and stumbled onto this comical picture (story behind it was just as comical) and figured it was a good pictorial description of what happens when you leave your black valve open while hooked up.

Have you gotten inside to look? :B

My bet is there IS a nice thick layer of that stuff on the bottom of your tank. My guess, 2 years...1/2 your tank is sediment. Poop needs to 'float' in water to be able to exit. The amount of water from a flush does not fill the entire bottom of the tank to float the stuff out the opening. It's just sitting there and when the sediment gets high enough 'some' of it exits!

So if the black valve is left open, how does the poop get that high? :h

The liquid drains away through open valve allowing the solids to accumulate and build toward entrance point. If valve is kept closed the liquid creates a slurry and over time breaks the solids apart.

Hope this helps

OK - I got it... TMI, but I got it 😛

Way back when I was a kid, at scout camp all we had were outhouses. We used to pour some lye down there every week or so......

LOL, just got a chuckle when I saw it. For the record, my arm would never fit down there and even if it did, I would choose to use a pressure washer to break up the pile.

GOOD One! :B

This visual Needs to be a sticky on the forum for all RV'ers who:
A. Ask why it smells inside their RV.
B. RV'ers who still insist it's ok to leave the black tank valve open when parked.

As everyone is clicking away and saving this pic, I see this being used for the answer to a lot of black tank questions!

YES..:E I have also seen the "pyramid" in composting toilets like in state, fed parks.
