Why has my hot water pressure suddenly dropped?
If hot water pressure suddenly stops entirely but cold water flow continues just fine, then a control valve may have been left closed, or a valve may have failed internally (appearing to be turned on but actually “off” internally due to a broken valve stem part), or a valve or pipe elbow may have become partly blocked …
