How can I fix my unvented hot water cylinder?

The tundish/discharge pipe on the unvented hot water cylinder is constantly trickling cold water, causing a small over spill into the airing cupboard. What is the cause of the problem and how can I fix it?

sounds like the prv (pressure relief valve)
you need a engineer with a g3 cert to work on unvented systems.
