I want to change the hookups to the washing machine in basement. The shutoff valve is not working so I turned off the main water supply. The water is now shut off to all the upstairs sinks and the cold water in the basement. However, the hot water faucet in the basement stationary tubs just keeps running. I shut off the valve to the hot water tank, at least I think it is off unless that is not working either.
Any help as to why the hot water keeps running will be appreciated.
