High Wall Black Tank Emptying Directions

[PlanetKid]

Waiting for delivery of new Rockwood HW277 and need information on the best method for emptying the black tank. Although I've camped in a pop up for 12 years, this will be our first camper with a bathroom. I have been searching this site and others and can't find much info on the subject. I see that the gray water tank is separate and can not be used to flush the black tank. We often camp for 7 nights, and it is just the 2 of us. Do you think the 12 gallon capacity tank will be sufficient?

No, sorry man. You'd need over twice that black capacity to get thru 7 nights. It's great for nighttime use and then just use the campground facilities when you're not dragging out of the bed.

Same with Barry. We had a 7 gallon black cassette in our pop-up. With using it (just for the pees) throughout the day for 3 of us, I'd have to empty it every other day.

I disagree. I don't think I have ever gotten half full. You don't use as much as you think. Be sure to use rv toilet paper. And grab a rinsing wand for when your packing up and emptied your tank. Then put wand down toilet and run for about a minute or so.

RV toilet paper, or the cheap thin stuff that you can test for it's dissolving properties.

Thanks for the feedback, but what I am most interested in learning about is the full process for emptying the black water tank. The process appears different than a standard TT setup. Where can I find online detailed information about the procedure? Can I off load the contents into a blue jug and bring it to the dump during a week long trip to keep using the tank when filled?

Not really that different from standard TT. make sure sewer hose is secure in drain. Then twist and lock sewer hose to black valve. Use disposable gloves. When all is set up, pull valve open and drain - takes about a minute. When "flow" has stopped, insert flush wand from up top and run water thru for a minute or two. Then close valve and walk the hose to remove the remaining water in sewer hose. All done.

Get some "drop ins" for Wally World. It will make life smell alot better.









Here are links to the above products that help in draining the grey water. This way you don't have to hold the hose when draining.

You should really be more concerned about your grey tank usage. 12 gallons in grey water goes FAST.

I routinely camp 7 nights in mine, with 4 people in my camper, and with the "only at night" rule in place (ie go to the bathhouse during the day) we never fill our 7 gallon black water tank.

The grey water tank is another matter entirely, we fill that nearly daily.

It empties just like a TT.
