Taps in the bathroom

Hi Everyone. Have you got an idea why my taps in the bathroom stopped working. It started with the cold tap in the bathroom sink which gradually stopped. Then just this afternoon, the hot tap for the bath tub also stopped working, I noticed that it started flowing weakly two days ago and now has totally stopped.

Thank you in advance.

Periodically the water department flushes out the mains and this puts a bunch of loose crud in the lines. Try taking the areator off and see if it is plugged up. Some tub/shower valves have a screen on their inlets...that might be harder to get to.
