Hello all, When we flush the toilet we get a burp/bubble before stuff flows down. It acts as if there is no vent air. Could the vent be plugged. If so how do I clear it? Dave
If you can't figure out anything else go up on the roof and remove the vent cap. Verify that the vent pipe has not dropped down into the tank which does happen. If the pipe is still above the roof line try running a hose down the pipe to make sure it is not blocked.
