I've had a new sink fitted. When the tap is turned off water continues to flow slightly before stopping! The question I want to ask is this a plumbing issue or is it a poor quality tap?

It depends on the type of tap - if you have a cartridge one (which only turns part way) - it is normally a bit of 'spill' being expelled (like power showers) - If it is a standard tap with fully opening taps then it could be a bit of flow past the washers - especially as the washers will need a bit of time to bed down. Like all things - you get what you pay for - so a £30 tap will not ever be as good as a £130 tap - ask your plumber who fitted the tap for their thoughts as well. Cheers Mat

Hi I can only think this is a monobloc mixer tap it's totally normal I have a £330 tap over my bath it just what's left in Yr tap from the valve to the outlet nothing to worry about

might not be my tap will empty the steam out after the taps our off and sometime will get a few drops just come out from time to time

If the tap drips 3-6 times after you turn it off then it’s not seating properly so yes, not a plumbing issue, only the taps. Go for bristan, I have never found them to be a problem whether it’s quarter turn ( ceramic discs) or washered
