Hi,
I have aproblem with my seat toilet. When I flushed it, then the water inside the bowl will decrease slowly, and sometimes it can flushed successfully but I can see bubble and gurgle sound. But if I flushed it with a bucket of water (aaprox 7 liters), then the problem gone, but still can see bubble and gurge sound. I have check the water level of the tank, and its about 1/2 inch from overflow pipe.
We have try remove the toilet and check the drain pipe, it seem OK with the drain pipe because we can pour some water inside it and it seem normal (not clogged)
For about 5 years we didn't have such problem with our toilet.
My questions are :
1. Do seat toilet have some kind of air vent ?
2. Should we replace the toilet ?
Thanks and best regards,
Hendrik
