A few days ago our toilet got quite seriously blocked. We tried plunging, the mop and paper bag trick, flushing, bailing, washing up liquid, coat hanger, hot water....eventually about 12 hrs after it blocked a can of Mr. Muscle unblocked it and our toilet worked again! Until a few hours later when I flushed the chain and it blocked again. Since then whenever it flushes (even if there's no paper towel put down there), it blocks, fills up, and then about 40 minutes later has almost completely drained right down to the bottom (it also blocked the sink for about 10 minutes one time). We were baffled because it only ever blocked when I flushed the chain, but worked fine for my mum. I figured out that by holding both the little and bigger flush buttons together, the toilet won't block and will work perfectly. However this isn't too practical as if you apply even the slightest bit of pressure to one button over the other it will block again. We had the flush buttons replaced about a week ago and I've noticed it's been playing up since then. Does anyone have any ideas what to do?
The one time this happened to me it turned out that my 1.5-yr-old had flushed a quarter-turn piece of his hamster run into the toilet.
The snake went through it and we couldn't find any obstruction.
So we decided to replace the toilet.
As soon as it was off the floor we turned it over and there it was. A nice piece of blue curved plastic.
It was wedged in such a way that the snake made it pivot to go through, but water flow would catch in it and it would turn back to block the flow.
So the answer in our case was to remove the toilet and give it a thorough examination.
Please forgive my ignorance. I have yet to come across personally a toilet with buttons so in order to be able to help you we will probably need to know the make/model of your toilet since it does not appear to be your standard toilet. Up until your last couple of sentences I figure you simply had a serious clog that would most likely require your local rooter service. But now it seems as though your toilet may have some sort of controls that I am not familiar with so would need more information. Pictures might help as well.
One thing though, do you have access to any of the sewer/drain clean-outs? If so, have you tried to run a snake in them in case it is a clog, could save the call for a service person.
