Good morning folks. We ran out of hot water last night 🥲. We have a traditional " Y " plan setup, cold water to the kitchen then up to a big tank in the loft where it feeds the rest of the house. Taps started sputtering and reduced to a trickle before stopping completely. Climbed up into the loft and found the cold water tank empty. Texted our plumber who suspects debris in the ball valve mechanism. He's going to pop in at 08:30 and take a look. I suppose the plumbing work in the kitchen might have been the initial cause. At least the incoming mains tap will provide water for coffee ☕️
