Hi fellow bruised knuckled pipe stranglers, help please! I have been using some of the above washers ( Screwfix part no 34550) in the past I have used them on basin taps without any trouble, but today I was messing about under the bath to change a pair of bath taps that would not stay put in the centre of the ludicrously big holes the bath is supplied with. So I got some centralising washers which are supposed to fit ½" and ¾" taps how the hell do you get the centres out! I assumed that they just snap or punch out but no even butchering with pliers would not shift them. In the end I used a hole drill and finished with a half round file. Surely there must be a better way than wasting 20 minutes to make the darn things fit.
