When I fist started RV'ing an old timer clued me in. When black tank is dumped and flushed be sure to add water back to the tank so "solids" don't stick to bottom of tank in the drop zone. Add enough so you have an inch or so of water on the bottom of the tank.
I know it's counter-intuitive to put water into a tank you've just drained but it really won't impact the number of uses possible. Will definitely make the disposal process quicker..
Yep ... like Mike said ... I got same tip and we always prep the tank with at least 3-5 gallons so we are ready for next trip.

Thank you because that smell was horrid. The grey is down line from the black and creates extra vacuum on the black tank."

So we filled both grey water tanks, then opened them both about 1 second before opening the black water valve: the suction from the grey water running down pulled the clog loose. And ran the black water flush for a good long time after, to clear it out good. We may just fill the black water tank again by running a hose into the toilet, and dump again, to be extra sure of clearing out anything left in there.
Thanks for sharing the solution you found. I'll have to put that one in my bag of tips and tricks.

I have been RVing for many years without a problem with a poo pyramid. At the end of every season, I drain my black tank and dump 20 pounds of ice into the tank. I drive around for 10 or 20 miles, fill the black tank with water and drain again. When I look down the toilet the tank looks brand new.

I've been using the GEO method for several years. No smell, and no clogs. We have very hard water, and most campgrounds out west use well water which is also hard. The Calgon water softener makes perfect sense to me.

Lots of water here as well but we also use a toilet chemicals and TP. We start each trip with adding the toilet chemical and 5 gallons of water so there is plenty of water to dilute the solids.

We wander so as a bonus the black tank gets a good rinse going down the road.

Ive never had a clog, because I add 2 4 gallon buckets of water to the tank when I drain and flush it. If there is a line I dont' do it then but when I get home to be courteous to my fellow campers.

What we have had is a leaky black tank valve that was caused by TP caught in the seal and allow effluent to seep by.

The short term fix was to add another gate valve at the discharge to prevent any "leakage" before I could get it fixed with a new valve.

Our permanent fix was two fold.
1. A small waste basket for TP next to the toilet.
2. I added a Bidet Seat so the paper has no solid waste on it in that basket.

Problem solved...............I kept the gate valve though.............glued it in place.........Just in case!

Make sure

I got a call from the buyers of my Forest River tt, their first trailer. They described the exact same problem written about here. Turns out they were opening the grey water tank valve instead of the black water tank Valve.

I buy the cheapest laundry detergent I can find at DG. I add a cup of more to every tank along with chemicals. Seems to help things flow better. Also , always use your blackwater flush after /during emptying. If no blackwater flush, have someone flush toilet continously while/and after dumping

Black tank not draining

I'm a retired RV mechanic and I did not see anyone suggest a method I used many times with success close black and grey valves hold sewer hose as high as possible fill with hose then have helper open black valve pressure of water in hose will push clog in to tank return hose to dump port quickly and tank should follow

Mr billthecamper: your suggestion is filed away. Hopefully I won’t have to use it but that is a great tip! This is the first time I have seen it mentioned. Thanks!

This is a great idea.

To go a step further, after pushing the clog back in, I would then re-close the valve, refill the hose, then open the valve and put the hose into the sewer outlet all in one fast motion (takes two people). The water that's filling the hose should then create a suction (siphon), in addition to the pressure of the water in the tank, to create a larger flow rate out of the tank.

The northern 2 ply can be used but the tank needs lots of water and use tank treatment every time. LOTS OF WATER! Everytime!
If you usually dump at 2/3 full, finish filling the tank with water first. And after dumping, run several gallons of water in the tank before you use it again. There has to be water and treatment in the tank for the solids to break down.

X2

ANY toilet paper can be used if you prep the tank after dumping, using enough water when flushing the toilet and waiting until the tank is full before dumping. We've used the SAME toilet paper that we use in the house as long as we've been camping (40+years) and never an issue.

Putting toilet paper in something other than the toilet is something we'd never do.

Yea...

Any solution that includes the phrase "hold sewer hose as high as possible" makes me a little leary.

Same here on all counts. I use Camco waste digester, controls odor and breaks up TP, and doesn't hurt septics. (No formaldehyde). Been doing the same thing for 40+ years without issue.

I always thought Robin Williams was a smart guy. I'm surprised he fell for that.
Oh, wait, I guess when they call it acting they can get anyone to do anything. I hope the stuff in that hose wasn't the real thing.
