Hi all,
I've been DIY fitting a new concealed cistern toilet in my downstairs cloakroom for the last couple of weeks (in evenings etc.). I've finally got it install installed and leak free apart from one joint .
The leak is coming from where the thread of the flushing mechanism passes through the hole in the bottom of the cistern. The the bottom of the cistern is not completely flat (molding marks) and the washer for the outside of the joint is very solid plastic, I'd expected something more flexible / rubber. I originally had a leak from the thread but a single turn of PTFE tape has sorted that, but I've still got leaking at the very top of the joint stack, because it isn't sealing against the cistern itself.
Any advice, the instructions say not to use sealants etc. on the plastic parts, I was tempted to use silicon and then do the joint up and let it all set, but I don't to cause more problems with the silicon damaging the plastic cistern or the pipework / nuts.
It's a homebase "buxton" system if that is of any help.
Any advice welcome, I'm beginning to dispair
