I've recently moved into a rented property with a dual-flush toilet. When flushing the "new" water seems to be sent directly "under" any paper/waste thats in the bowl, causing it to "roll" over the top and not evacuate down the pipe. This happens whether one or both of the buttons are pressed/held to flush, and it's starting to get a little embarrassing when we have guests round.
Since it's a rented property there isn't an option to replace anything, but I wondered if there were any quick fixes I could apply?
A littie further information; the toilet seems reasonably new, there doesn't seem to be any blockages around the rim and and we've cleaned everything. The pressure is good; the water reaches right round to the front of the bowl where it creates a good jet, but it's this jet that seems to run directly under the waster causing it to roll.
I doubt it's a problem with the water pressure - the jet is powerful, maybe a little too powerful, which could be why it's flushing directly under the waste rather than over it, pushing it down. We've cleaned it thoroughly, though it wasn't necessary as there were no deposits or blockages. I've a feeling that it may simply be a design fault of the bowl. :(
