Anybody else had similar. I replaced our En-Suite approx 6 months ago and when replacing the toilet used the existing tap connector (copper not flexi) but renewed the fibre washer. After approx 3 months SWMBO noticed the joint between the connector and infill pipe was weeping. I investigated and found that the new fibre washer was in fact split, so I replaced it and everything OK. I periodically checked it and no leaking at all. Yesterday SWMBO noticed a weeping again whilst doing the cleaning. I have investigated again and another split washer! The seat of the tap connector and infill pipe are not rough, cut, sharp etc. Why would this happen after 3 months and not straight away? I have replaced the washer today but this time I have used a suitably sized O ring.
Cheers
John
