People need water every day, so the safety of drinking water is also extremely important. Today, most of the drinking water is transported in drainage channels, and pipes used to transport drinking water use different materials than pipes used to transport waste water.
Your home may have a plumbing system that uses all types of materials to supply pipes, but don't be surprised to find several or even all of the following types of pipes, each with its inherent advantages and disadvantages. Determining which type of pipeline is the safest depends on your personal concerns and preferences. Next, I'm going to show you which pipe can be used for drinking water?
1, PVC water pipe
2, Copper pipe
3, CPVC pipeline
PVC stands for polyvinyl chloride. Among the different types of plastic pipes used for water supply, PVC has a variety of plumbing applications from drains to pipes. PVC is also common in swimming pools and spa systems. PVC is usually white but can also be in other colors. You can usually judge the purpose of the pipe by the color and markings on it. Vinyl chloride and organotin compounds used in the manufacture of PVC are hazardous chemicals, and vinyl chloride is called carcinogen. Organotin is a metal compound used to stabilize PVC and help it resist thermal degradation. These chemicals are usually locked inside the material and pose a small threat to the human body. In some cases, however, they can be immersed in drinking water. The solvent used to clean the PVC and the glue used to bind the segments together contain strong solvents.
The main drawback of the PVC tube is that it cannot be used in hot water applications. When exposed to hot water, PVC warps. This means that it cannot be used to transport hot water to sinks, bidets and washing machines. When exposed to ultraviolet light for a long period of time, it also degrades, including ultraviolet light from the sun, so it is best suited for indoor applications or underground folds.
But many homeowners and builders choose copper over most other types of pipes, although rising costs and the easy installation of other materials could eventually replace the metal. If water is slightly acidic-pH 6.5 or lower-copper may leak out of pipes and enter drinking water. Copper pipes have become the standard for most domestic plumbing applications. The long service life and durability of the pipeline make it an excellent choice for many applications. It has good heat resistance and corrosion resistance. Copper is not degraded by water and can be used safely with drinking water. This type of piping is mainly used for hot and cold water distribution, as well as conventional HVAC systems for refrigerant pipelines. Although used in gas pipelines, this is no longer allowed in most jurisdictions. However, copper has a major disadvantage, that is, the price. This is one of the most expensive plumbing materials and is at high risk of being stolen at construction sites or vacant homes.
CPVC stands for chlorinated polyvinyl chloride. It is usually (but not always) cream-or gray-white plastic. This type of pipe can withstand temperatures up to 180 °F (depending on the schedule), so it can be used for hot and cold water in houses or mobile houses. CPVC can be used in most applications using copper pipes, but for a number of reasons. It is considered a better choice. First, the interior of the CPVC tube is smooth, which means that it is almost free of water noise, including a "water hammer", compared with the copper piping system. Second, it has good insulation and can prevent energy loss in hot or cold applications. CPVC is also more flexible than metal tubes and provides more multi-function. Finally, it is very fire-resistant. However, it is slightly more expensive than PVC and will split if freeze is allowed.
To sum up, each pipe has its own advantages and disadvantages, please come to Eagle Technology Co., Ltd. to choose the right pipe for you, so that you can have a safer drinking water experience.
