Burping toilet

Hi All, what would cause the 1st floor toilet to burp a bubble every once in awhile?

Most common cause I've found is a plugged up vent line.

Agree with Joe, and, this time of the year, the first thing that I do is look at the roof and see if the vent stacks are visible. Doesn't happen every year, but must have been the winter before last that we had at least 3 or 4 times when the snow accumulated enough during a one or two day period to bury the stacks. That's all it takes sometimes.

Clogged vent because you have a clog... Partial clog? The line fills up and blocks the vent..

Roots? Belly in pipe? Many factors..

A snake and camera are in order...

Note: Misconception is water will not flow with blocked vent. This is untrue. Vent are for allowing traps not to be siphoned out..

Well no snow to block the vent yet,lawrosa, could a filled septic tank cause this,it doesn't happen to often just notice it once in awhile.

yes filled septic... Often denotes too much water use and/or a failed leach feild. Also can be a clog at the baffle in the tank..

When was your last pumping?

If you pump the tank and water comes back into it from the field then you know the field is the issue..
