Tundish showing signs of water? Either a constant drip, small stream or a large flow of water going into the Tundish is a sign that one or the safety features of the pressurised cylinder has failed.
With this particular job it was the Temp & Pressure Relief Valve causing a small stream of hot/warm water to flow through the tundish. The valve in situe looked as it had never been changed being the original from the time inital installation.
A quick partial drain down of the system and a slight alteration to the pipework and in went the newer version of the valve.
It is always better to safe when it comes to a unvented pressurised cylinder. If you see signs of water inside your tundish get in contact with a qualified plumber.
