Where is water shut off valve for Rheem 40 gal electric water heater?

The water does not have a shutoff valve. The valve should have been separately installed, usually directly above the water heater on the cold water line.

Pop off valve keeps popping off and makes hot water run all the time

Is the water extremely hot?? If so, then I would probably recommend new thermostats for top and bottom of the unit. The only time these temperature related overflows are activated is when the water temperature reaches a certain temperature and they are there to safely relieve the pressure/temperature so the unit doesn't explode.

If water is not terribly hot from normal, then I would say the TMP valve ( the valve that you are referring to) needs to be replaced and can be done easily by turning water off, and picking one up at any home improvement store for your model and just unscrewing the one you have out, putting on pipe thread sealant on new and rescrewing the new TMP valve into the tank.

Good to go after that,

Let me know!

Pop off valve dripping Rheem 50 gal electric valve at bottom

If you are reffering to the drain valve at the bottom of the hot water tank. It may be leaking due to the O ring being cracked or worn out. You can either drain the tank and replace the valve or you can buy a hosebib brass cap and thread it on the existing valve. There is no cause for alarm when doing this as this valve is just to drain the tank when replacing your hot water heater

Low amount of hot water

You say a very new water heater. You won't get 40 gallons of hot water from a 40 gallon water heater because the continuing influx of cold water will cool your hot water down. However, it appears that your bottom water heater element needs replacing. If the top element is bad, you'll get no hot water. If your bottom element is bad, you'll get "some" hot water. Try replacing the bottom element. DON'T FORGET to turn off the electricity AND water first (closeby towels are also handy)!
