A clogged toilet on Christmas isn't exactly the present that everyone is looking for. If you are dealing with a clogged toilet, there are things that you can do that may be able to help you unclog the toilet. One may not work on its own, but the combination of various methods may work enough for a plumber to get to you.
You will have noticed over the years that dish soap is slippery and heavier than water. It also has chemicals in it that dissolve grease and other dirt, which may also help with clogs. If you have a clog, you can dump a lot of dish soap into your toilet. Being heavier than water, it will slide down the drain and into the clog. You can let it sit in the pipes for some time. It won't hurt if you leave it sitting for even an hour or more. When you've let it sit long enough, fill up a container with very hot water. Pour that water down the toilet. The hot water should be able to reach the clog where the soap has been sitting and lubricating the clog. Theoretically, the soap will allow the clog to move. Try flushing it to see if it goes down. You can always try it again if you need to. You can also try plunging the toilet after you've put in the dish soap and let it sit. The slipperiness of the soap can help with the plunger too.
A toilet auger is also known as a snake or pipe auger. The auger is a cable with a claw on one end and a handle on the other. You can hold on to the end with the handle and then feed the auger into the drain. When you get it into the drain, all you need to do is turn the handle and extend the cable further. That will also let the claw on the end of the auger grab into the clog and start to break it up. It can take a few minutes, but you may be able to break up the clog enough for it to just run down the pipes and then completely out of the pipes.
If you have a clog that you can't get rid of, you are going to have to call for plumber services to come deal with the problem. However, you may be able to get rid of your unwanted Christmas problem on your own as a quick fix.
