To a kind soul......please,,reply with the sequence used to cleanblack water tank.Many thanks in advance,Demetrio.

There are products available from Camping World from there retail locations or from there online store. If this has not been done on a regular basis you might need to do the job more than once. In extreme cases I have heard stories about using these products but not filling the black tank completely and hooking up the tow vehicle and going for a ride. The sloshing in the black tank will help to break things loose--Good luck!!!!!

Do you have a solid waste blockage, or what? just my humble opinion but... it IS a sewage holding tank, it doesn't need to be clean.

Well, I suppose that depends upon how dirty it is, an if you have any solids stuck in there, like the famous "poop pyramid." Assuming you have no hard build-up, cleaning the tank is really pretty simple.1. Drain the water and contents.2. Fill with water.3. Dump.It's really that simple.To clean a little better, for example, if your sensors are not working quite right.1. Dump your tank.2. Fill the tank with water and dump again.3. Fill the tank with about 5 gallons of water and bit of laundry soap or a few good squirts of Dawn dishwashing liquid and take the camper for a good 20 minute drive with lots of turns and stops and goes. This will let the water slosh and beat up the insides of the tank, breaking anything free that might be stuck to the sensors.4. Return home and dump the tank immediately.You can incorporate back-flushing with a Flush King, you can incorporate spraying down the inside of the tank with a toilet wand on the end of garden hose, you can add a bit of bleach and go for a drive, any number of thing like this. All will work well to keep the tank clean. Clean water sloshing when on the road is really the most effective way to keep them clean. Dump immediately when stopping.

Many thanks,no,the RV is stationary,but I'm planning to clean it regularly,I was told,in my particular case,every two or three weeks.Once cleaned,how much watershould I put in the tank,a gallon,maybe two? I'll do it with a solution from WM.

Hook up the hoseOpen black tank valve. Let most drain out.Close valveTurn on flusherListen for tank to get half full or soOpen valve again keeping flusher onflush for a few minutesturn off flusherlet tank drain. Close black vanveOpengray water valve and do the same.I DO NOT see the need to put any chemicals in your tank. Bad for the envirnment. Bad for your wallet. Money down the drain IMHO No need for RV toilot paper either.

Sequence to use to clean up "black water tank",please.

You were told wrong.

I've never "cleaned" the black tank and I've been camping for close to 50 years (and we've had stationary sites at times).

Use plenty of water when you flush and let the tank get at least 3/4 full before dumping. No need for chemicals or other treatments.

Do you leave your black tank valve open all the time? Or do you leave the black tank valve closed and empty the tank when its almost full, then close the valve again?

Many thanks in advance,Demetrio.

Many people swear by the "GEO Method" of keeping their holding tanks clean. Don't know the exact proportions, but you'd likely want to tailor a bit depending on tank size. Boils down to some original Dawn dishwashing soap and come Calgon (or other) bath water softener. Dump a "dose" down the tank, then use lots of water when flushing. Leave your black tank CLOSED until ready to dump or the liquids will run out leaving the solids behind. Personally, when I dump, I hook up the flush hose and turn it on for a few seconds before pulling the handle, just to get more water in the tank, and I leave it running while dumping. When it gets down to empty, I'll close the valve and leave the hose running for a few minutes (DO NOT WALK AWAY OR YOU'LL FORGET, TO YOUR REGRET!!), then dump again. Repeat. After that, I dump the grey tank to help wash out the hose. Again, personally, I've never used a clear elbow, nor felt I needed to, and I've never had an issue. YMMV... Also, personally, I twist the ends of the hose together to seal them, then toss them in a plastic bin. :B

You don't need anything in the tank but water. Soaps and other chemicals just leave buildup and film on the tank and sensors. When you are done flushing tank put 5 gallons of water in so the "solids" stay submerged and do not dry out and make concrete.

Get at least 3 days worth before dumping. Hook up rinser & turn on to add at least a few gallons of water. Open dump. When most is out close dump while letting rinse system spray away. As long as nobody is waiting at dump let it run for a few minutes. Open dump valve again & let it run till just rate of water going is is flowing out. Close dump valve & let rinser run another minute or so to have a few gallons in the tank to slosh around.

The only time the tank is left as empty as possible is for winter storage.

Instructions are pretty good from what I have seen.

We always add a bag of ice before we leave and a gallon of water and it knocks all of the poo loose...and if you add it before you arrive and dump when you get there you will see a beautiful brown agitated solution come out.

Sorry but it is true.

X2 on this

I never dump with less than 3/4 full black tank. Even with a full hookup at campground I always tow home with black tank almost full. I have a clean out connected to our septic tank at home that I can position out TT next to. I dump black tank then fill back to 3/4 full to full with garden hose then dump again. Sometimes twice till clear elbow on swer hose shows clear water draining. I stopped using chemical treatments a long time ago.

More water generally takes care of a lot of black tank problems. I've had good luck cleaning/deodorizing mine by filling it completely full of water and letting it sit for a few days or longer with a strong dose of chemicals. That should dissolve anything stuck to the sides.
