Because of the freezing temperature increases pressure in the pipe causing it to burst.
The water in your pipes will freeze, and then burst!
because when they get cold enough they will bust and if it is water pipes they will definitely bust if they freeze.
It is important to protect water pipes so they don't freeze because when water freezes, it swells. If water is trapped inside the pipes the pressure from it swelling will cause the pipes to burst.
If you didn't, they could freeze in the winter and burst.
some times when temperatures go really cold in winters it causes water to freeze and as the water in pipes starts to freeze, the expansion that takes place when water freezes causes pipes to break
Yes, copper pipes can burst when the water inside them freeze. This is because, when the water freezes, it expands with a considerable amount of force, against the pipe, bursting it.
Because if they freeze they may burst, then you will have a mess and no water.
They freeze. Water expands when it freezes and the pipe breaks.
You gave the answer in the last part - you don't want them to freeze and burst during winter.
If you don't insulate water pipes or protect them in some way from the cold, the water inside the pipes can freeze. This causes you to be without water until the pipes warm up enough to thaw. Also, when the water freezes, it can expand and burst the pipes which will then need to be replaced. Save yourself the aggravation of having no water and the cost of replacing pipes by insulating them. To protect pipes in an empty or unused building, you can pour anti-freeze down all drains and in the toilet to winterize them.
To protect them from frost damage. In cold weather, 'standing' water in cold pipes can freeze if the temperature drops low enough. When water turns to ice, it expands - which could cause the pipe to burst. However - you wouldn't know if it had burst until the ice had thawed !
if water freezes in pipes it will break the pipes, literally.
