Hi, I have a toilet that has water running into the toilet pan. I would like to try to find out if this is something I can fix myself but the problem is the toilet doesn't have a ballcock or look anything like the toilets I have seen in any of the diagrams on pages that offer advice. The toilet is in an apartment which is 4 years old and the toilet has a push button fixed onto tiling which is built around the toilet. Sorry to be really vague! Anyone have any thoughts?
