First trip of season and no hot water. Water in tank is hot but not getting to sink/shower. I think it is mixing valve. Any hints on how to fix without replacing. I did check all faucets closed. D...
If you are getting water flowing on the hot side of your faucets, but it's not hot, you either have a bypass valve in the wrong position or one of your showers (usually outside) is turned on on the hot and cold side and the button on the head is in the off position. Make sure your shower valves are turned off.
