i went to a house with a dripping mixer tap. The make of the tap was franke. The spout was dripping on the hot side. I removed the ceramic disc valve and set off for the local plumbers merchants. They sent me to a place that makes kitchens and this man fixed it for a fiver. He told me a new valve would cost £22 and would drip in a year and a half, but he could fix it that it would never drip again. i asked him to tell me how he did it but he wouldnt tell me. i would like to know what he did because i put it back in half expecting it to drip, but hey presto job done and dusted. Can anyone tell me or guess what he did apart from Paul Daniels.
