water heater leakin pressure release valve

Here is a good explanation of a closed water system. In this case it includes back water flow preventers in city water systems.
Closed Water Systems cw Hot Water Tanks
QUOTE: "The Solution: The best solution to thermal expansion
is to control the pressure it generates within a normal,
safe operating range, well below the emergency setting
of the relief valve. This can be accomplished by
installing an expansion tank which will allow thermal
expansion to occur, but without causing a dangerous
increase in pressure."
