You can check whether the identification information is clear, whether there is any omission and so on. In the purchase process, we can also check whether the water pipe is uniform in color and shiny.
2. When purchasing 6 pipes, you also need to check whether the wall thickness of the water pipes is uniform. We can also use a ruler to measure the inner diameter, outer diameter and wall thickness of the water pipe to check whether the size of the water pipe meets the standard. Under normal circumstances, the length of a ppr water pipe is 4 meters. You can also measure whether the length of the water pipe is qualified during the purchase process.

When we buy water pipes, we can check the authenticity of water pipes through the anti-counterfeiting signs.
