I installed a new toilet in the basement about 5 days ago, used it maybe 3-4 times. Today I flushed and it filled up like it was clogged, after plunging it some water went down but when I flush it fills up like its clogged. I pulled the toilet off checked the pipe and its clear, poured water down and its flowing( not filling up). The wax ring flange wasn’t lined up 100% Could a bad seal of the flange of the wax ring cause this ? Toilet is a Kohler Elmbrook
