I have lived in this mobile home over a year and this is the first time this has happened. A couple of weeks ago I replaced the water line going to the toilet tank. I only mentioned this because this is the only thing different, although I don't see how this could have anything to do with the problem. After taking my bath, I unplugged the stopper from the tub and I heard water bubbling up in my toilet. Then I noticed water was all around the toilet on the floor. Please help! I did't change any lines under the house when I fixed the water line to the toilet tank, I only put a new shut off valve and water pipe to the tank on the line that was running up out of the floor.

Stop beating yourself up over this. The fact that you changed out the toilet supply has nothing to do with your present blockage.
You have a blockage downstream from the tub and toilet. You could pull the toilet and snake from there but the easiest way would be to snake from the tub overflow. (see image).
Unscrew and remove the overflow plate,(The one with the drain lever) and pull out the tub stopper. You now have a clear shot at the trap. The way you were going in through the drain it ran you square into a tee that you can't get around. Now feed the cable( 1/4" best or 3/3" with a small tip. You can rent a Ridgid K50 sink cable.) About 2' down you will run into the bend of the trap. Crank and push at the same time to work around it. Your blockage will be found in the lateral pipe going to the stack. You shouldn't have to put out more then 10 or 12 feet. I have found tub and shower clogs to be mostly hair and the worm should auger into it and pull it back. After you snake pour a few pans of boiling water down the drain. This will loosen the grease and flush the mess out into the main. Hope this helps and thank you for rating my reply. TOM

Thank you Tom, unfortunately my tub does not have an overflow, so I suppose I will have to pull up the toilet, which needs to be pulled up anyway. The person who put it in did a very poor job and it was never steady anyway, apparently the wax seal needs to be replaced also, that would be the reason water came up through the floor around the commode. At first I thought maybe the toilet overflowed with water from the tub. But after I pulled up the carpet from around the commode I could see the real problem. Anyway, I can't run any water in my house, flush the other commode, wash clothes or anything, all the water goes all the way to the back bathroom, up around the commode.
Where are all the single men when you need them? LOL!

OK! So you'll have to pull the toilet. Do you need instructions or will you call in outside help? Note. Since your bowl was rocking that ruptured the wax seal. Along with the wax seal purchase some plastic shims and an small tube of Dap White Tub and Tile Caulk. The shims will steady up the bowl and caulking the bowl will give your job a professional look. Good luck, Tom

Thanks so much for your help Tom! I appreciate you going the extra mile. This is a job for the big guns, pulling a toilet is more than my back could take, I'm just a little girl! Hopefully, my son in law is coming tomorrow to fix it for me. My dad was a plumber several years ago and I found a (plumbers) snake in my little building but it was just a coil of metal with some little funny head thingy on the end of it. I don't know if he will be able to use that or not I don't see how he would actually "feed" it into the sewer lines. I may have to rent one, but I will be so glad to get it fixed.

If your son in law needs help in snaking the sewer line all you have to do is ask. Good luck, Tom,
