Once you turned the valve 90 degrees (which is CORRECT- it only turns
90 not 180) did you get more hot water?????
Water Heaters can be plumbed with 1 or 2 or 3 bypass valves!
Those with only 1 have check valves that make the system work.
I don't think you need to go buy a bunch of valves and put in a bypass
system because I think you already have one. If you didn't already have
a bypass system you wouldn't have that pipe that runs between
the hot and cold inlets on your heater.
Strutbuster1- that photo you posted in msg 6 appears to be in the
correct position. The handle should indicate flow. Your handle is
in line with the incoming cold water. If you turned it 90 deg the handle
would be in line with the bypass line which is the pipe that runs
BETWEEN the hot and cold on the tank.
As mentioned by others, you need to see if the water in your tank
is actually hot or not. You can VERY CAREFULLY open the safety valve
and see if the water that comes out is hot or just luke warm.
Be careful! Wear rubber gloves and a long sleeve rain coat or something
so the water won't burn you. It should not be scalding hot but very
uncomfortable. Thermostats are normally not adjustable and they are
typically 130 or 140 F.
If you have hot water then the valve might be defective. Rarely folks have
reported the plastic valve stem broken and the handle moves but not
the valve itself.
See if you actually have HOT water before moving on to the next step.
