Result is broken pipes, so symptoms are:
1) no Water at faucet
2) leaking water elsewhere.
Why is the second paragraph a contradiction of the first? If hot water pipes 'Absolutely' do not freeze faster than cold water pipes then why the comment about the cold water pipes having a larger diameter which causes them to freeze at a slower rate than the smaller hot water pipes? Also, the word then in the last line should be thanand there should be an a between usually and larger. And, piping should be changed to pipe.
Water turning from a liquid into a solid. Of course by FREEZING it.
A 7 % sodium chloride solution in water has a freezing point of -4,38 0C.
Water has no pollutants or extra chemicals with lower freezing point to cause it's freezing process to slow. Coke has many chemicals with lower freezing point then regular water. Juice doesn't have the chemicals(most of the time) but it has fruit, the fruit has a lower freezing point then water so therefore it lowers the overall freezing point.
It will certainly not keep the water in the bucket from freezing and, if the temperature goes low enough, the bottled salt water will also freeze.
Water EXPANDS as it freezes, hello.
Heat tape is just for keeping the pipes from freezing, it does not heat the water. That's what the hot water heater is for.
There is no single best way to keep pipes from freezing. Insulating (wrapping) pipes is a common method. Leaving the cold water faucet open just enough for a slow drip is another method to prevent freezing.
Yes, they can
water expands when frozen.
Because if they freeze they may burst, then you will have a mess and no water.
One can prevent pipes from freezing during cold temperatures by ensuring water runs through them. A good idea to do this is to let the tap drip. Draining the water system when going on vacation during cold spells can help pipes from freezing as well.
Pressure has nothing to do with pipes freezing. It is just exposure to cold.
water expands on freezing
If the pipes weren't cracked from the water freezing and expanding then you could be ok.
Fill with anti freeze solution or keep the water running.
Assuming you don't mean water heating systems, and just mean normal fresh (drinking) water systems, then they freeze at 0 degrees Centigrade like all water. But in the case of for example a home, the plumbing protected from freezing in a few different ways. Firstly most homes that are lived in have some form of heating, so this keeps the ambient temperature of the water in the pipes above freezing. Pipes that are in places more likely to be exposed to freezing, such as lofts, and roof cavities will be insulated with pipe lagging to protect them from freezing. Plus remember those pipes in roof cavities will benefit from heat rising from the home/building, helping to keep those pipes above freezing. If the subject of your question is in relation to 'burst' pipes caused by frozen water in the pipes expanding and literally tearing the pipes apart, then this will start to happen at about 20 Degrees Fahrenheit or -6 degrees Centigrade. Remember that a little freezing is not a major problem, as plumbers sometimes use special freezing kits, that will freeze a short section of pipe to block it off temporarily, while they work on the pipes.
