I removed my upflush toilet to replace some flooring and since I put the toilet back onto the upflush kit, there is not enough pressure to flush solids as it did for the last 6 years. I replaced the ballcock, not any better. I have a sink draining into it and the upflush works as it did before. I'm not sure what to do next.

Any help/advice would be appreciated.

I removed my upflush toilet to replace some flooring and since I put the toilet back onto the upflush kit, there is not enough pressure to flush solids as it did for the last 6 years. I think I may have the answer. Read on.
In my capacity as shop trouble shooter I began to run into a slew of complaints on our new construction that were just like yours. I knew they all couldn't be " bad toilets" so I went looking for the cause. I found that when installing the new bowl that the wax ring had been forced out into the discharge pipe and blocking the free flow of water. When the water hit it a backpressure was set up preventing the siphon that makes a good flush and the solids just swirled around while the water went slowly down. I had to set up meeting with our plumbers and show them the problem and how to fix it. When you set the bowl, put the wax seal down on the flat side to the closet flange. Then take your hands and bevel the wax seal outward so that when you set a bowl on it the wax is forced out instead of in blocking the flush. The customer complaints stopped and I had less work to do. Try molding the wax seal so it doesn't choke down on the flush. Good luck and let me know how you make out. Good luck, TomTom

Something new that may be relevant, I snaked out the toilet to the extent that I pulled up some filthy water that was very similar in color and smell to what I experienced when the toilet was off. Should I also have pulled up some wax?

I snaked out the toilet to the extent that I pulled up some filthy water that was very similar in color and smell to what I experienced when the toilet was off. Did you use a snake or a closet auger?

Should I also have pulled up some wax? Not necessarily. The only way to tell is to reset the bowl and bevel the wax seal. Since it flushed before and not after this just about the only solution I can come up with. Pull the bowl, bevel the wax sea land get back to me with the results. Good luck, Tom

Not Helpful to me, but Can I ask you a question since you seem to know about upflush toilets. Why does mine not work at all? Also there seems to be a primer container above the commode with an open hole in it. If I turn the water on, then try to flush the commode it squirts water out of the hole. (We moved into a home with this in the basement and no one in my area (butler, pa) seems to know anything about them. Thanks

Not Helpful to me Of course it's not helpful for you. It's a answer I gave 4 years ago to someone else, You're responding to a 4 year old dead thread, By "upflush toilet" do you mean ejector system?

Why does mine not work at all? That question covers a lot of ground but tells me nothing, Does the pump not run? Does it run but nothing happens? If you have a complaint please post it with all the details you can give me.

What feeds this "primer container" and where does it connect to? Can you give me a picture? Back to you, Tom
