I am refitting my bathroom and have a slight weep on the bath waste. The 'leak' is coming down the threads of the waste in the bath. From underneath (ignoring the U bend) I have the following senario from the bottom up.
Threaded section of waste Big White plastic nut Rubber Waher Overflow 'cup' Rubber washer Bath (8mm thick) Silicon sealant Top of waste outlet.
All items are new and as supplied with the bath.
This is the forth bath I have replaced in my life and the other three never gave me a problem and IIRC hhad the same or similar set up. Any ideas anybody please? It's driving me mad!!
Cheers
John
