These taps were bought as part of a complete bathroom suite from Homebase. All the taps are fine apart from the hot water basin tap. When closed the lever (handle?) Doesn't line up with the front of the tap. For example, if imagining it as a clock face the lever doesn't stop the flow of water completely until you reach 25 past! i'm a perfectionist and this is really getting on my nerves. Any suggestions on how to fix it? Will I have to take the whole tap to bits? I'm a complete novice at this type of stuff. Thanks in advance for any replies.
