💧 Is your hot water cylinder trying to tell you something?
If you’ve noticed a drip—or worse, a steady flow—in that little black funnel (the tundish) next to your cylinder, don’t ignore it! 🛑
Your unvented cylinder is a high-pressure system. When water drips into the tundish, it’s a safety warning that something isn't right.
As shown in the video, it could be:
A failed Temperature or Pressure Relief Valve 🌡️
An issue with the Pressure Reducing Valve 📉
A flat or burst Expansion Vessel (that big white tank!) ☁️
Ignoring these signs can lead to higher water bills, wasted energy, and potential damage to your system.
