Hi all, I've been having trouble with my toilet for a while now. Sometimes it flushes very slowly and sometimes not at all. I don't believe its clogged. I've run a snake all the way down it a bunch of times and when I dump a bucket of water in the bowl it goes right down. The tank fills as full as it can possibly go and the holes underneath the rim flow just fine and the flapper seems to be functioning just fine. Most of the time the bowl fills 3/4 of the way and slowly drains to its normal level. I can't figure it out but yesterday I went down into the basement and the drain coming from that bathroom goes straight down and the angles UP into the main line that goes to my septic tank. I'm assuming that should be angled down so gravity takes it into the main line. Not sure how it got this way but I'm thinking that is my problem. Before I start cutting pipe I wanted to check in for any input from someone who knows more about this than I do. Thanks in advance!!
