This Is The Most Genius Solution To A Clogged Toilet I've Seen. Brilliant!

In case you don't have a plumber, here is an ingenious solution which is developed in South Korea, but i would highly recommend to use plumber.

 When you flush, do you see the water coming down from under the rim to rinse the bowl? There are holes all the way around the underdside of the rim, and those holes go right into the tank. That means when you use this device, in addition to forcing the "clog" down through the trap, you are forcing dirty water back into your tank, which before was just pure, clean water. Your toilet tank will forevermore be contaminated with the poop water, and probably smell accordingly. Use a plunger. Credits: Youtube
