Hey guys,
Need your help with something. In my apartment ever since I moved here we have a problem with water, where for both the kitchen sink and the bathroom sink, if you turn the water on hot it runs hot but only for 1-2 minutes, then it’s like the hot water runs out and it becomes cold.
Luckily for the shower this doesn’t happen, so we could take normal showers. As the situation was annoying but we could live our lives we never thought much of it.
As of yesterday, the water in the shower stopped running hot as well, but this time it’s not like it runs hot for a while and then stops, now absolutely no hot water comes from the shower and we can’t use it. The bathroom sink is the same but for some reason the kitchen sink is like before (has hot water for 1-2 mins).
I wanted to ask you if anyone knows what is impacting the hot water? We have the following devices, the first on the bathroom and the second below the sink, but a friend told me that the thermoacumulator where the hot water comes from is for sure common to the entire building.
Anyone has any tips that might help?
Thanks a lot!!
