I need to replace all four tap washers in my bathroom. Trivial job or should be, but the taps need 5/8 washers without a central hole. (The washers fit tightly into a circular brass recess at the bottom of the plunger.)
Has anyone any idea where to source these washers?
I have searched on Google and asked at plumbers' merchants without success. I can't use a ball valve washer because they are not thick enough.
