Hi All, I'm new to this group and after some advice please. My boiler has started to drip. I've taken off the front and have located where the dripping water is coming from. I have a Potterton Combi Performa 28... And the leaking part is best described as

'fixing%20potterton%20performa%2028'(Page 5) I look at the 3 way valve assembly, and there's a brass-material like thing that looks a bit like a brass round clock face behind it. The leak is coming from the nut on the outside/middle of this, but it looks as though there's a tiny little hole in it anyway which I'm presuming should be there.
Any suggestions what the problem could be please?
Thanks, Jon.
