Water too hot

Our gas/electric water heater water gets too hot. I have looked and found no adjustment or . I remember seeing something in the form, but can't find it. Any suggestions?

Thanks

The temp on our old TT was adjustable (gas only). The new TT (gas/electric) doesn't seem to be adjustable. Maybe the thermostat(s) can be replaced for a lower target temperature.

There is no temperature adjustment that I'm aware of. Dilute it down by opening the cold handle.

Note the bypass valve normally used for winterizing that separates the cold from hot on the water heater as illustrated below. It can be partially opened to mix hot with cold and make the water cooler.

My 2008 had a mixing valve near the water heater - you had to pull a panel to get to it. It had a 2" dia grey knob but it couldn't be turned because it had serrations inside the knob - that was before the dremel tool was invited to the party. To remove the knob, you have to remove a small amount of wax inside the hex head button screw. I found that minor adjustment between early/late season and dog day of summer season would help keep the hot regulated.

Really is the same as adjusting the knobs inside or the bypass valves outside

You could have a bad thermostat that is not cutting the burner/heater off soon enough and the safety overtemp might be your only control.. I'd spring for a new thermostat to see if that fixes the problem first.

I had an issue with the water being too cold on my 2008. I adjusted the mixing valve as described above to restrict the amount of cold mixing with the hot coming out of the heater and I had hot water again.
