But when the tragic incident occurs between those who are near or dear to one another--if, for example, a brother kills, or intends to kill, a brother, a son his father, a mother her son, a son his mother, or any other deed of the kind is done---these are the situations to be looked for by the poet.
When water is heated it expands. For example, water heated from 90Â°F to a thermostat setting of 140Â°F in a 40 gallon hot water heater will expand by almost one-half gallon.
Your water heater is filled from the cold water running in a tube to the bottom of the water heater. Since heated water rises, the top element just maintains the upper part of the water as the outlet hot side is on the top. So, If you start out with good hot water - and it starts to quickly turn cooler - you know the bottom element is bad + you can put your ear up to water heater and hear which element is on. I am with the person who said to change them both. Turn off incoming water supply - let off water pressure at another faucet.
