I guess you are asking about daily air temperature. Once the surface has melted, the only concern is the above ground pipes freezing. If you leave the pump running all the time, the chance of freezing is very low.
Insulating water pipes helps prevent freezing by maintaining the water temperature above freezing point, reducing the risk of burst pipes and water damage. Frozen pipes can disrupt water flow and cause costly repairs if they burst due to ice expansion, so proper insulation is key for winter protection.
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.
The time it takes for water to freeze in underground pipes depends on factors like soil type, depth of the pipes, and outside temperature. In general, pipes tend to freeze if temperatures remain below freezing for several days consecutively. However, well-insulated pipes are less susceptible to freezing. It's recommended to take preventive measures, such as insulating pipes and allowing a slow trickle of water to run during very cold temperatures to prevent freezing.
Heat trace systems typically draw 3-15 watts per foot, depending on the specific type and application. This power output is necessary to maintain the desired temperature and prevent freezing in pipes, roofs, or gutters.
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.
Heat tape is used to prevent pipes from freezing in cold weather by providing a controlled amount of heat to the pipes. It wraps around the pipes and is usually self-regulating to ensure that the pipes stay at a safe temperature.
If it is at freezing temperature, then you have an issue with uninsulated pipes.
When the temperature is 47 degrees, NOTHING is in danger of freezing !
If the outside air temperature is above about 30 degrees F, then yes; if the temperature is below that, then you should open the faucet to a slow trickle of water. If the water is moving, it probably won't freeze in the pipes and break them.
Pipes can burst in freezing temperatures because water inside them expands as it freezes, creating pressure that can cause the pipes to crack or burst. This is more likely to happen in uninsulated or exposed pipes. Insulating pipes and keeping a steady drip of water running during cold weather can help prevent them from freezing and bursting.
