All water heaters should have a pressure relief valve, otherwise they could burst.
the hot water valve shut off valve shuts off the hot water. The cold water valve shuts off the cold water. ;()
No because water heaters have a safety valves and when the pilot light goes out the safety valve shuts off the gas
No. If the heaters are designed for 220V they cannot fun off of 110V. Also running a 1500W heater off of 110V would require a dedicated circuit. So four 1500W heaters would require 4 dedicated 110V circuits.

it sounds like there are crossed lines. if there is no water upstairs there has to be a valve that is off. even if there is low pressure it would eventually fill the line and you would get some water.
Water not on at street 'city' valve, or other valves--after inside main valve--off.
shutting off the valve
By shutting off the water supply and replacing the valve
Outside at the main shut off valve. Showers/Bathtubs do not normally have a shutoff valve like sinks and toilets. The main water valve for the house must be turned off.
No, electric water heaters do not need a pilot light. The heating element is heated by an electric current (similar to the 'eye' on an electric stove or the heaters in a toaster). When the circuit is completed, electric current flows through the element, and it gets hot, and when the electricity is turned off, the element starts cooling. In a gas water heater, the pilot light is a flame, which is always burning. When it's time to heat up the water, the main gas valve is opened, and the pilot light ignites the gas, so that the main burner heats up.
Blow off valve faulty or expansion tank needed at water heater.
