It sounds to me like both of the gate valves are probably bad and need to be replaced. I did both of mine and now have a set up that can be removed with removing to stainless clamps that hold the entire unit together. If you have a problem with sewage messes get a plumber and it can be done in about 30 minutes.

Cut the line near the tank leaving enough room to reconnect the PVC pipe. There will be a mess but you can hose out the entire compartment to clean it up.
Trying to repair it without a mess is almost impossible. If you cut the line you can put a preasure washer tube into the tank to bust up any build up you may have on the bottom of the tank.
Chemicals are not going to correct the problem you have with the defective gate valves and I would try and drain what ever you can out of the cheater dump on the drivers side of the coach. The valve on that side is probably also in questionable conditiion and will need to be replaced.

It's like eaten barbeque ribs you gotta get into it and get a little messy and if you can't, call a plumber who will jump on it like a fly on a terd.
Good luck.

If there is a connector, (preferably clear) that would fit on the drain which you could attach a hose then you could see if the city pressure/hydraulic was breaking through then if it did you could then close the valve remove the hose setup attach the drain hose and open drain.
That is if the valve is not stuck shut.

I've used ice cubes to help break up solids. Just dump a few bags and then drive an hour or so, preferably on a bumpy road. The ice helps break things up.

gee, we are sure full of good ideas. to me it comes down to how much of a rush are you in.

now for my two cents worth.

it does seem like the valves need to be replaced or repaired. if they are sticking partially shut all it will do is force the outcoming pooppressure to be higher when it does come out.

i would work on getting all the liquid out, fix the valves so i am sure they are working. then work on getting what you think is a bunch of solid poo dissolved. i replumbed my toilet and know my tanks pretty well. it is hard for me to imagine anyplace that there is a plug of poo THAT big that it would stop all the outcoming stuff from coming out. i really suspect the valves are stuck. if you do replumb the valve and put completely new ones in. make sure you do yourself a favor and do what wally says. his new setup is really nice as you can remove it all in a flash to repair or replace the valves in the future. now i know you have a slight problem in that all your plumbing is probably covered with an aluminum panel, wally and i dont have that.

btw, to clean my tank, i put a little water and i think 15 bags of ice down the toilet then went for a long drive.

also, i am sworn off of nasty chemicals in the tank after cleaning up a bottle of formaldahyde under the bathroom sink the first time after buying the coach 3 years ago. it just about killed us. i use bacteria now.

thats my two cents worth. but, please, when you ignore me like most people should, please video what you do with hydraulic and air pressure to compression explode the poo out. i really want to see it. please put a camera in the bathroom too so i can see the stream shoot up out of the toilet.

happy monday

tom

Hey Wally, how about some pictures of your valve setup?

My coach a 1991, had a pump on the curb side that also drains the tank into a garden hose. Also there is an air actuated valve on mine on the curb side that may be operable. It drains out the bottom of the coach, but has the standard sewer connection you access from under the coach.

I'll take some photo's tomorrow but somewone will have to coach me on how put into this program. I have not put any photos on this site although I do put them into adjuster programs that I work with.
I agree with Tom that cleaning the tank is a minor problem, you have valve problems. I did mine about four years ago and they are now starting to become tight and I will be replaceing them sometime this summer.

If there is no "water" coming out when all the appropriate valve handles are in the open position then either the valves are broken or there is a solid mass plugging the dump line. One way to find out which it is is to open the valves, ensuring that no liquid is appearing and run a snake gently up the open connection. If the valve is broken you will hear a plastic knock sound, if there is no sound when the snake stops or a soft sound then you know it's a poopy plug.

If it's the latter I think I might try getting a short piece of sewer hose attached to the outlet with it long enough to be turned up so its end is above the top of the tank. With the sewer hose horizontal run a snake in to just touch the plug and then raise the end of the hose above the level of the top of the tank and see if I can then get the snake to break through the plug. If it does break through you will feel liquid rising in the hose and you can quickly pull the snake and shut off the dump valve. Use a 5 gallon pail to collect the liquid while lowing the end of the hose. The next steps are obvious.

good luck

Jon...a well thought out method of attack. I would just add that maybe a second set of hands should be available to quickly shut the valve so the person holding the snake, and short sewer hose doesn't accidently drop the wrong thing while attempting to close the valve....
