Ok... How do I unblock it?

 

[muggles]

Simple way - throw it in the bin and buy a new one
Occasionally effective way - take it outside and blast it through with a hosepipe
Professional way - connect a powerflushing machine to it. Or throw it in the bin and buy a new one

You can do it yourself, replacing the washers is advisable, you should be able to get them from a plumbers merchant or maybe B&Q
