Tundish dripping on a Joule Unvented Cyclinder

[Kamsingh27]

I have recently noticed that the tundish is dripping ever so lightly.

I had a new boiler fitted in Nov and at the time the tundish was flowing a lot but the plumber fitted a water pressure valve which seemed to stop the dripping, but it has started again. Pressure on valve is same as was originally set...

Any help appreciated.

Is it warm or cold water dripping?
Either way it needs a G3 qualified plumber to service/repair
