Yesterday we saw that water is going slowly and there is dirty water left.
We poured hot water and try shirt hanger but nothing changed. Is there any practical way before calling a technician or Mario Bros?
My past experience (prior to low-flow toilets, don't know if this would work with those) is that you can usually correct this problem by clogging the toilet more. Put several wads of toilet paper into the bowl, and make a "slow flush" -- lift the lid on the tank, reach into the water there (which is clean), and lift the flush valve just a crack, to let the bowl fill slowly. When the water in the bowl is just below the rim (and the paper wads have finished clogging the trap), push the flush valve back down to close it.
Once this is done, use and ordinary plunger, emphasizing the push stroke over the pull -- this will push the paper wads against the partial clog, and usually push it on around the curve of the trap. Once the water in the bowl begins to flow normally, let it finish cycling (and the tank finish refilling), then flush one more time. Everything should be back to normal, and no special tools needed.
Get yourself a toilet snake. They consist of a long, spring like cable with a slightly larger end with an 'auger' type point. Mine has a plastic housing which holds about 3 - 5 feet of this spring and then 'feeds' it out as you rotate a handle.
To start you uncoil about 12 - 18 inches and work it down the drain and past the toilet bend. Then you rotate the spring while feeding more out and down into the drain. With some luck and patience, you should be able to dislodge the clog.
I watched many youtube videos about solving my problem and could not find place to sell me the tools like suggested here and in videos , also it is the first time something happened like this in my house. So I after my search I decided to buy a gel to recover my problem.
It took me 3 minutes to solve my problem without involving with any dirty water and buying any tool that I will probably took place in my house.
I just pour 2 litres of hot water in my sink then pour the chemical just in two minutes i started to hear some noises like melody. Water was going as like as first day.
Thanks for your kind replies.
