I’m going to cut to the chase. If you’ve tried plunging and it didn’t work, you can try a drain snake. If you can get a hold of it with that, then your left with no choice but to take up the toilet. The following tells how.
Turn the water off beside the toilet and try to drain it. Remove the water line from the toilet.
Once it’s drained removing the tank is the best option, although I’ve removed a whole toilet completely intact.
After it’s removed, finding a wrench that is large enough and unscrew the large bolt type plastic screws on the bottom of the toilet.
Now keep in mind there is a ring around the bottom that is all gooey. It’s there to help the toilet from leaking. This will have to most likely have to be replaced. Lifting carefully, lift the bowl up and set it on something. Now if you didn’t get all the water out, you may want to have old rags around to catch water. Nothing new. Now you have the access to see what is blocking the toilet. If you don’t see if lying on the gaping sewer whole in your floor, you will have to reach inside the toilet from bottom up and check. Please wear gloves.
If you still haven’t found the problem, you will need to run the drain snake down the sewer line to see if you can feel anything. Once you have found your problem, you can now go in reverse and replace the toilet.
If this however didn’t solve your problem, then a plumber may be your next call.
But this shows you anyone can do home improvement jobs, even women.
