i have a mixer tap, it is quite old. Its easy to turn the hot water on but the cold handle will not turn at all. I have taken the handle off - the cap etc and have sprayed WD40 on the screw thing but it is still not budging, what do i do, any suggestions?

Check with any of the DIY outlets or local plumbers shop see if the do 'head replacements' for your mixer and replace both. Depending on the type: Remove centre cap and handle screw remove handle Udo tap head.

Capstan types have a side screw then undo chrome cover, use a cloth and wrench cloth protects the chrome. remove tap head.
Take head to any plumbing outlet in most cases better with the small shop they are more knowledgable for a replacement tap head.
