I put dog waste in the toilet tonight and when I flushed it, the water rose to the top of the bowl like it was going to overflow. It didn't overflow though. Then it suddenly just went down on its own and very little water filled the bowl. Is it going to overflow when I flush it again?

Did it raise to the top, swirl around and then just drain out or did you get a deceit flush? Is it flushing OK now? Did any other fixtures gurgle or burp as the toilet flushed> Back to you, Tom

The blockage is within the bowl. Take plunger and give it few good pumps. Make sure the plunger is fully submerged under water while pumping. Back to you. Milo
