Hi, Our toilet seems to burp big bubbles upon flushing. This started happening about a year ago and we’ve been living here for 25 yrs . The internet says it is a venting problem . Do you have any suggestions?
Good morning everyone!
Through my past experience, I always look for certain laymen terms used by the customer. In this toilet noises arena, I’m looking for one of two terms ... "glugging" or "burping". When I hear the term glugging, I have usually found the issue to be a vent-related problem. As the slug of water is traveling down the pipe, the area behind the plug has to be filled with something, and that something is air. In the event the slug of water has no access to air, due to a plugged vent, that area behind the slug will be replaced and nature is going to get it from somewhere, so it steals it from a trap of another fixture by sucking the trap dry and causes a "glugging" sound. Burping, (in my experience), has usually meant a blockage down stream, or the reduction of flow from down stream. In your case, I believe there is a compromised flow path. It could be calcium build up in the weir of the trap of the toilet, and the opening terminating the toilet may be reduced in size. You may try throwing a gallon of vinegar in the toilet and allowing it to sit in there for a day or so, however, I don’t always believe that does a thorough job of resolving the problem. A new toilet could be warranted or the sewer may be partially plugged. Call and have us come out with the sewer machine and try to determine what the actual reason is for your burping issue and get it handled!
