Question about Water Heaters
I came home to hear the water heater with a hissing sound...didn't think much of it until the next afternoon, it was still making a hissing noise and I noticed the pipe that goes thru the wall to the outside was leaking, rather heavily...there is a sort of relief valve on top of the heater and when I lifted it, warm water leaked out and about 2 minutes after that, the water stopped leaking out of the pipe outside...does anyone know what this could be or am I able to fix this problem....my water bill will be thru the roof otherwise :(
Bad relief valve or too much pressure in the tank. Does water heater system have a pressure blotter tank that allows for expansion(an expansion tank)

It sounds like the pressure/temperature relief valve is stuck open slightly, and draining out the PVC pipe. This is common in poor water locations.
You can try lifting the release on the top and letting it pop shut again, but chances are good that by now the seat has been destroyed by the water passing over it. Replacements are available at any home store, just remember to drain the water out of the heater so you don't flood the garage. MAKE SURE YOU TURN OFF THE POWER FIRST OR YOU WILL BE REPLACING THE ELEMENTS ALSO! You will need to wrap the threads with teflon tape before installing the new valve.

SOURCE: we have a leaking water heater.
As far as a shut off valve on to the water heater, if there is one you should be able to see it on the water line going to the heater. This is not common in mobile homes. If there is not one I would strongly recomend you install one when you replace the heater. If it is going to be a while before you replace the heater you might consider draining it and cutting into the inlet line and installing a shut off valve, so you can turn the house water back on. I hope this helps.
