Periodically when the toilet is flushed rather than the water going down the drain it fills the bowl up. This is more ,noticeable when there is paper or waste in the bowl. If I plunge it then at some point it completes the flush but what appears to be air in the system is then noticed. Also if I go away for awhile and come back the water level goes down in the bowl. And ideas what's wrong?

Hi Chester,

Everyone here are volunteers. We are not always on. Have to give your post some time to be seen.

Check original post for answer.

Someone will always get back to u, it just tacks time.

Chuck was correct to criticize you.
You posted a question and a minute later complained because we didn't answer fast enough? That's not how things work here.
Here's the solution you were looking for,
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 and thank you for rating my reply.. Tom
