PPR water pipe selection:
1. Appearance: High quality pipes are made of high standard imported PPR materials, with a smooth surface and complete identification. The accessories also have anti-counterfeiting labels.
2. Toughness: Good PPR pipes have good toughness and can be easily bent into a circle without breaking. Poor quality pipes are more brittle and can easily break when bent.
3. Heat expansion and cold contraction: soften under water temperature.
4. Service life: High quality products are guaranteed for 50 years, while inferior products only last for 5-6 years.
The common problem with PPR water pipes is water leakage. In addition to purchasing high-quality water pipes, installation standards are also important:
1. When using PPR fittings with metal threads, it is necessary to use sufficient sealing tape to avoid water leakage at the threaded area.
2. Do not tighten the pipe fittings too tightly to avoid cracking and water leakage.
3. It is better to cut off the end of the pipeline by 4-5 centimeters.
4. Winter construction should avoid stepping, striking, colliding, and throwing.
5. After installation, a pressure boosting test must be carried out, with a pressure test time of 30 minutes. The pressure should be increased to 8-10KG, and the pressure drop should not exceed 0.05Mpa within 30 seconds under the test pressure. The pressure should be lowered to the working pressure for inspection, and there should be no leakage or leakage.
6. The water pipe is easy to install on the top for maintenance. If it goes underground, it is difficult to detect water leakage and inconvenient to repair.
Reminder:
If it is found that the wall paint is moldy and foamy, the baseboard or wooden floor is black and has fine bubbles, and the roof and pipe wall tiles are damp and leaking, the pipes should be checked as soon as possible.
