Hi there I have A Problem with my upstairs toilet. When it is flushed it seems to flush normally but then the 'tide' ones up the pan by a couple of inches (not the whole way as when loo is totally blocked) and slops back and forwards a couple if times before the level settles. Once settled you can see particles swirling in the pan and over time the water becomes brown/yellow until next flush. We assumed was localised partial block and my OH has bought a twisty took for unblocking drains om a hardware shop and rodded it. I've also tried bleach and dishwasher detergent (not together!) but it remains this way? What else cam we try and what might the problem be? We are quite poor and my OH is very good at practical things so would prefer to solve it ourselves if we can. Thanks!
