Help settle a plumbing dispute?
Our house is around 70 years old & it's previous owners remodeled (2nd floor) attic & put in a bathroom. It's obvious that the insulation wasn't done properly because in the cold winters we have here, the hottest setting on the shower results in barely tepid water. After tiring of my complaints, my husband's quick fix was to increase the temperature on our water heater in the basement. While this helped with the shower's water temperature, NOW the hot AND cold water pressure in the bathroom sink (both the attic/2nd floor bathroom sink, as well as the 1st floor bathroom sink) is gone. He thinks this a coincidence and thinks we need to call the local water authority, versus a plumber. He doesn't understand why it would affect the cold water, and also why it would only seem to affect the sinks. I think he's crazy, and somehow the change in temperature has affected the pressure in the sinks (although not in the shower). Any thoughts are greatly appreciated.
