Ok, this is my 1st post so be gentle! I replaced my toilet just over a week ago, the first waste pipe/pan connector leaked where it was connecting to the toilet waste outlet, not badly, just a few drips, now i have another one on there which was fine for a few days, and THAT started dripping after a few more days...All seems to be aligned etc but i just dont get why it is leaking. Now its really annoying me....Any ideas???? I have measured several points around the outlet on the actual toilet and it is round to within 2mm and the actual rubber seal is quite a bit smaller so its a snug fit.
