Toilet is clogged, but main line seems to be clear
Have a ongoing problem with my toilet and I am at my wit's end. I am trying not to call a plumber, because the last time someone snaked the drain, he was here for ten minutes and charged me $240. So... the toilet has been clogging and slow draining for a couple of months now. I have tried all drain cleaner's and the some acid stuff too. No help. Every time someone goes to the bathroom, I have to plunge it. I have like three different plungers too. Some that plunge down, and suck back up, and one that just shoot air into the hole. My husband pulled the toilet up and ran water into the hole, and it drains fine, so it leads me to believe it is a pipe in the toilet or something. I have from time to gotten dishwashing liquid and plunge and it will go down easier, and will actully work for about three or flushes afterward really good, but then it's back to either not draining at all and I have to plunge 50 times to get it down, with force. Or it will sluggishly swirl down, and I have to plunge and flush three or four times to get it all to go down. I have three kids, and at this point, I tell them NOT to flush the toilet and I have to go in there and work after every last one is done using the bathroom. Any suggestions here? Or am I doomed to call a plumber?
