sounds like a simple valve replacement, post the job on this website and get a plumber to sort it for you

Hi either the washer in the tap has come off or if it is a quarter turn tap the ceramic discs have broken, you may have an isolation valve under the tap on the inward pipe work which you can turn off, this will isolate the faulty tap allowing you to function normally.

post this in the jobs, plumbing section and get a plumber round to fix it

may I suggest you post a job as we need more info.

if your tap wont turn off then you need a new tap. but if your not getting hot water, there could be a number of reasons.

This sounds like either your washer for your hot tap has broken away, or your tap seat has been worn down through a dripping tap. I would suggest a new tap, its obviously flowing and not allowing the new water to warm up.

It sounds like the washer on the tap is not holding the pressure back as it should. I had to go and sort the same problem last week for one of my custermers. The part you need should cost under £1. If you have any plumbing experance it is very easy to do.

It sounds like your taps valve has broken, if the tap won't switch off. No hot water could mean your boiler is not working properly.
