Well it reacts slowly with water (relative to the other alkaline earths -- but not slowly enough -- your water pipes wouldn't last very long.
Yes, especially if you wanted to cook anything containing water in the saucepan: Calcium reacts violently with water.
Most water softeners remove calcium and limestone. These are not really harmful to humans, but cause a scaly build up in pipes and tanks.
Hard water refers to water that has very high mineral content, which affects its behavior in pipes and its affect on other chemicals like soap, where it often causes the formation of soap scum. Hard water also has a tendency to form deposits in pipes. Normally you wouldn't WANT to make water become hard, and there are systems for trying to reduce the "hardness" of water in the pipes of your home.
By distillation or evaporation of water
They will undergo an acid base reaction and the products would be calcium chloride, calcium chlorate and water.
Cold for the calcium carbonate is disolved by hot water.
I think aluminum isn't used in water pipes because it's a type of paper metal. Therefore, it's way too fragile. Water's weight might rip right through it.
Usually dissolved calcium is the cause of scaling in pipes that carry water.
Yes, especially if you wanted to cook anything containing water in the saucepan: Calcium reacts violently with water.
At water treatment plants, calcium hydroxide is added in order to up the alkalinity and pH of the water. This makes the water less corrosive to pipes. Aluminum sulfate is used to make impurities coagulate.
Water Hammer.
sodium and water often make babies. you dont want your water and your sodium making pipes, do you?
calcium chloride and water
pipes

Not very pure. The water is dripping off a coil that has dirt and pipes that have calcium deposits and probably some mold.
Iron rusts easily when combined with water, and drain pipes have water flowing through them. If iron was used, the pipes would rust within a few days.
