Temperature and Pressure Relief Valves

[Damien1991]

Hi all, new to the forum and just looking for some opinions.

I have an electric flow boiler and indirect cylinder in an unvented sytem.

I am wondering can i run the boiler T&P relief, cylinder T&P relief and ERV in the same 28mm drain pipe to outside. Using three seperate tundishes or would they require 2 or 3 seperate pipes?

Thanks in advance

Do you have your unvented g3 ticket? If not then leave it alone and get a qualified engineer in to sort it for you.

Good advice above. These can and will kill you.
