What is this and is it normal for it to drip?

[Fanh]

Hi all, I am new to this forum. I just wanted to see if anyone knows what this part is called. And is it normal for it to drip? There's no visible leak anywhere. And I believe the droplets go into the waste pipe. But something could be wrong if it's not meant to drip. Thanks in advance!

Looks like a tundish to me.

If you google it you'll get a much better explanation than I could give you.

It is a tundish. It looks connected to an unvented cylinder. You will need G3 certified plumber to service your system. This is an annual service but I'll wager it's the first time you'll have heard of it...

As above you need a G3 engineer
