Toilet paper clogging the toilet

Question

We have quite an old toilet in our house and every time toilet paper is flushed down it completely clogs, it can be a little or a lot of toilet paper. It doesn't do this with anything else, just toilet paper. We've had to result to getting a bin next to the toilet for now. We had a plumber look quickly at it and he said he couldn't understand it but he's more of a kitchen fitter than anything else.

I have rodded the toilet on numerous occasions, well, everytime someone comes to visit and forgets about the 'no roll down the loo' rule.

Any advice would be very grateful.

Answer 1

Usually the old toilets preformed the best due to not having to comply with water saving laws (at least here in the States). One way manufacturers conformed to the new codes was to (among other things) narrow the throat of the toilet to increase the water flow to compensate for the decrease in gallons per flush allowed. But it sounds like the paper is getting hung up and caught somewhere near the toilet. Could be an obstruction(kids toy, toothbrush, pencil, etc.) just wedged in the bend at the toilet base or in the sewer drain under the floor. If it can't be plunged, snaked or augured you'll need to remove the toilet to visually check for obstructions. If there is a sink in the same room does the water drain normally? if so the blockage is directly after the toilet (in the sewer line) or inside the toilet.

Answer 2

you might have a thin physical obstruction like a pen or comb in there at the trap in the toilet (like ojait said). however, prior to pulling the unit, rent an inspection camera and send it through to see if you can spot it. then, a bent hook on a piece of wire is usually enough to dislodge it.
