1. These two water pipes have different appearances. Hot water pipes are marked with a red line, while cold water pipes are marked with a blue line. Therefore, you can distinguish between them by color.
2. These two water pipes also have different temperature tolerances. Hot water pipes can withstand higher temperatures, but cold water pipes cannot withstand temperatures exceeding 90 degrees Celsius, otherwise, the pipes are prone to aging or cracking. Therefore, only hot water pipes can withstand high temperatures, while cold water pipes cannot.
3. These two types of water pipes also have different pressure tolerances. Hot water pipes can withstand higher pressures, generally reaching 1.6~2.0, while cold water pipes can withstand pressures between 1.0~1.6.
4. These two types of water pipes have different uses. Hot water pipes are generally used for water heater systems, while cold water pipes are used for household tap water systems. Therefore, it is important to distinguish between them when using them.
