yes
depends on what type of piping you are talking about. Are you talking about frozen pipes bursting or High temps??
Thawing can only occur if something is frozen. Thawing means to defrost or unfreeze.
The best way is to first open all the faucets to release any pressure in the lines. If you can get to it; turn off the valve before the problem pipe you want to thaw. If the pipe has already burst, then you need to repair that section (if there was pressure then there might not be a burst situation.) Look around for signs of water leakage. Now you want to warm the pipes--don't rush this. Open cabinets to let the house's heat get to the pipers if it is a sink that is frozen. If the frozen pipes are inside a wall or in concrete other than hiring a plumber with a pipe thawing machine (assuming you don't have plastic pipes) the only thing you can do is warm up the room and wait. A hair dryer can also assist, if there isn't any water around the area. When you have found and repaired the area, then to prepare for next year, either insulate the pipes better or add a thermostatically controlled pipe wrap (to keep the pipes warm in colder weather.) Also consider rerouting pipes within a heated area.
Thawing means that you let a frozen thing like milk to melt in a natural way.
i should defrost it
No
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.
If you close all water shutoffs or all water faucets and the water flow indicator on your water meter is moving, then you might have a burst pipe. Also, if your pipes are frozen, no water is coming out of any faucets, and your water flow indicator on your water meter is moving, then you probably have a burst pipe. Hope this helps.
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.
Because when water freezes it expands thus bursting the pipes.
No. Time (and energy) are consumed just thawing it.
