If you have your own water heater there should be a shut off at the heater. If not I would look under the kitchen sink. There may be shut off valves at each fixture. If there is a central water heater in the basement, there would be a shut off to each unit.
Yes, you can set the temperature on this device.
All modern heater will shut off automaticly if they get tilted.
On any water heater, the shut off is on the incoming cold pipe.

How do I repair heater that won't shut off in 1998 chevy s-10 zr2 pickup?
Why does your 2001 Nissan Pathfinder heater fan stay on high even after I try to shut it off?"
car cuts off
The most common problem when a car's heater fan doesn't shut off when the car is shut off is that the resistor on the blower motor has gone bad. The fuse that powers the resistor should also be checked.
If you have a water heater in the unit there may be a shut off before that, usually at the floor or follow the cold side to a shut off. There may be an access panel behind the shower, possible in a hall closet but not always and there might be shut off valves there, but not likely. If your water heater is in the basement, there should be a shut off for each unit there.
As long as the water doesn't drain out of the heater somehow, no. What kind of car are we working on...
You will get some back pressure from the water heater. It will come out of either the hot or cold. Shut the tank off if there is a shut off there.
