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

1. Do seat toilet have some kind of air vent ?

The answer is yes. There is a pipe that goes to the roof usually close to the toilet position.
A snake should be run from the roof down this vent pipe to make sure it's clear.

I have one that most repair plumbers miss.. Look down at the bottom of the bowl. If there is a small hole, then that is a jet that starts the syphon action. If it's clogged the water will just swirl around and slowly go down leaving solids behind. Take your finger,(UGH! ) and run it around the inside of the opening. Over the years minerals build up and cut down on the syphon (flush) action. If it is rough or you feel build up, take a table knife and put a bend in it to get around the curve in the bowl and chip and scrap it clear. Next take a coathanger and clear out the holes around the rim. They start the swirling action. And last, check the water level in the tank. It should be 1/2" below the top of the over flow tube. And speaking of the overflow tube, Make sure the small 1/8" tube from the ballcock to the white overflow tube is connected so it discharges in it and that it's flowing when the ballcock fills. This is what raises the water level in the bowl. For a good solid flush they all have to work together. Hope this helps . Tom

Do seat toilet have some kind of air vent

Yes, Most are wet vented through the lavatory roof vent.
