Non Vented Water Cylinder - C & M

[kfm]

Hi,
I had water dripping through the tundish. I have changed the top valve and the non return valve and now the expansion vessel. Its still leaking water through the tundish. Any ideas?

Do you have your Unvented ticket?

if not you've broken part G3 of the building regs that are a legally enforceable document.

Turn it off, turn off the water to it and call in someone with the correct qualifications and experience.
