Average is 4ft, building code requires water pipes to be at least 6ft deep to be well below frost line and safe from frezzing.


At what temperature do pipes crack?

Water pipes should not of themselves crack at any temperature, however if pipes have water in them the water will freeze at temperatures below 0oC. If this happens then as the water freezes it will expand (ice is less dense than water) and as it expands it will either stretch metal pipes until they burst or crack ceramic pipes. For this reason external water pipes are buried at a depth to which the frost will not penetrate and internal water pipes are lagged to keep them warm.

When water vapor meets a surface that is below the freezing temperature and below the dew point, it turns into frost.


Will water in underground pipes freeze?

If the line is above the frost line. That can be 4 ft. down.


Why are taps left dripping in subzero areas during severe frost?

Flowing water does not freeze as easily a standing water, if the water in the pipe freezes the ice will expand and burst the pipe. Also water in the underground supply lines is below the "frost line" and will be above the freezing point, while when the pipes enter the basement or crawlspace of the house they will often be exposed to air below the freezing point. If you keep this warm water moving on into the heated part of the house it will not have the time needed to cool and freeze in the pipes passing through the basement or crawlspace.


How do you purge water pipes for the winter?

The best way to purge water from pipes for the winter is to open the tap for about 24 hours. It is also a good idea to install frost proof hydrants on all outside outlets.


What causes water pipes to burst when the outside temperature is 5 degrees below zero?

Water freezes at 0 deg C. As the water freezes in the pipes, it expands and it is the force of expansion which causes the pipes to burst.


What is frozen dew?

Words that work are frost, hoar-frost, or rime.


How does water travel?

Through pipes underground,then it flows into the river in which you got the water from in the first place.


What causes pipes to 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
