Yes I have fixed the tap in the kitchen by taking of the handle and replacing washers and springs. But I cannot get the handle off the bathroom tap to change washers/springs. The nut is corroded and even with WD40 it won't budge. So only cold water in the bathroom sink:(
Yes I guess I do need a new one. I am not savvy or brave enough to try to replace it myself so will wait till I can afford a plumber. Thanks for your reply:)
