Water coming out of tap when turned off

[AndyPR]

Hi. In the kitchen I have a mixer tap which, about once every hour or so, suddenly spurts out a small quantity of water when the tap is firmly off. There's no dripping or anything beforehand. Does anyone know what might cause this?
Many thanks

Do you have a water heater fitted under the sink?

 

[AndyPR]

No, I have a standard combi boiler

Has your tap got a largish spout?
Your tap washer or ceramic disc (depending on whether you have standard taps or 1/4 turn type) is slightly passing and after an hour or so the tap spout gets full and then empties

Yes, the spout is about 10" long and has 1/4 turn taps so your explanation would make sense. Thanks for your help.

That's normal, it all of a sudden just gurgles just once after use.

I know, after use! Fat chance.
