The most common problem with PPR water pipes is water leakage. In addition to purchasing high-quality water pipes, installation specifications are also important:
I. Stepping, knocking, collision and throwing should be avoided in winter construction.
After the installation, the pressure test must be performed. The test pressure time is 30 minutes, and it reaches 8-10KG. The pressure drop within 30 seconds under the test pressure is not greater than 0.05Mpa, which is
Check under working pressure without leaking.
Third, the water pipe is best to go to the top to facilitate maintenance. If you go underground, it is difficult to find water leaks and it is inconvenient to repair.
Fourth, when using PPR pipe fittings with metal threads, foot sealing tape must be used to avoid water leakage at the threads.
5. Do not tighten the pipe fittings too tightly, so as to avoid splitting and leakage.
6. It is best to cut off 4 ~ 5 cm of the pipe end.
PPR water pipe purchase:
First, thermal expansion and contraction: the water temperature will be softened.
使用寿命 2. Service life: 50 years warranty for high-quality products and 5-6 years for inferior products.
Ⅲ. Appearance: The high-quality pipe is made of 100% imported PPR raw materials, with a smooth appearance and complete identification, and the accessories also have anti-counterfeiting marks.
韧性 Fourth, toughness: Good PPR pipe has good toughness, can be easily bent into a circle without breaking, inferior quality pipe is more brittle and breaks immediately after bending.
