I have just spent ages replacing my bath taps ...I got the one tap fitted ok and all looks good so far .It seems secure and turning the water on and off does not make the tap move .. The other tap,which is the furthest from the outside of the bath is proving a different matter . Obviously it is trickier getting one hand on the tap to keep it straight and another on the spanner underneath . Firstly the rubber washer under the tap kept moving around so when the backnut was tightened it was out of place so I took the tap off and put Fernox LS-X on the underside of the washer and put it in place and left it for a while ( but probably not long enough) and tried again ...Now the rubber washer is all squashed up and stick out from under the tap around the back so I'll need to start again .
The old taps had harder nylon(?) washers and I'm wondering if I might be better using them instead .
Any thoughts . ?
