Water heater issue
Our hot water runs out very quickly all of a sudden. I worry that the hot water heater is failing. It is an electric model, about eight years old. Is there a way I can trouble-shoot the water heater before investing in a replacement? Can some other cause like a clogged pipe or something cause this issue? I did just turn off the water to my house a day or so before we noticed the issue. The water is running out quickly when showering in either the basement or the upstairs bath.
Thanks for any help or suggestions.
