The PPR pipe interface uses hot-melt technology, allowing the pipes to be completely fused together. Once the installation and pressure test are successfully completed, there should be no water leakage, making it highly reliable. However, this doesn’t mean that PPR water pipes are completely defect-free. While they offer good heat and pressure resistance, their long-term working temperature should not exceed 70°C. Additionally, each section has a limited length and cannot be bent easily, requiring more joints during installation. Although the pipes themselves are relatively inexpensive, the fittings can be quite costly. In this article, I will share some practical tips on how to purchase **PPR water pipe joints**, as well as how to address **leakage in PPR water pipe joints**—hoping to assist anyone looking for guidance in this area.
When it comes to overall performance, PPR pipes are considered a cost-effective material, which is why they have become the preferred choice for home plumbing upgrades. Here are some key purchasing tips:
1. Choose PPR pipes based on your home’s water pressure. Common pressure ratings are 1.6MPa and 2.0MPa, with corresponding wall thicknesses of 2.3mm, 2.8mm, 3.5mm, and 4.4mm. It's important to note that higher pressure doesn't always mean thicker walls. The factory-rated pressure is often higher than what you'll actually experience at home due to pressure drops along the pipeline. Most residential systems only need a wall thickness of 2.3 or 2.8mm for 1.6MPa pressure.
2. Many dealers offer discounts on the pipes themselves, typically around 6-6.5%, but accessories like elbows, tees, and valves are rarely discounted. For example, if you're renovating one kitchen and one bathroom, plus a balcony, you might need up to 15-20 meters of piping. Even with a 60% discount on the pipes, the fittings can still add significantly to the total cost. Water pipes and fittings are like ham and bread — they go hand in hand. So, many customers end up paying almost the same price even after discounts because the fittings aren't included.
To avoid this, make sure to clearly agree with the seller before installation that both the pipes and the fittings are discounted. Also, ensure that the final billing is based on actual materials used. During construction, check whether the pipes brought by the workers are new or leftover from other projects. Only proceed with the work once you've approved the materials.
Another important point: don't overuse joints. More joints mean smaller inner diameters, which can increase water resistance and reduce flow rate. Plus, too many joints increase the risk of poor connections. If possible, install the pipes in a straight line. If you’re unsure, perform a water shut-off test by pressurizing the system to 0.6MPa for 24 hours. If the pressure remains stable, the system is likely leak-free.
PPR pipes are made from random copolymer polypropylene, a material that has been modified for better mechanical properties, including higher tensile strength and impact resistance. This makes them ideal for hot water distribution. They are also non-toxic, hygienic, easy to install, and resistant to chemicals. Their excellent thermal fusion properties allow the molecules to fuse completely, eliminating the common issue of leaks at pipe joints. This feature has made PPR pipes widely popular in modern plumbing systems.
If a **PPR water pipe joint leaks**, it could be due to improper fusion techniques or poor-quality materials. To prevent such issues, it's crucial to choose high-quality, safe, and environmentally friendly pipes. One trusted brand is Germany Kuosheng, known for being the inventor and global leader in PP-R piping systems. Their patented raw materials are produced independently and offer superior thermal stability and purity. These properties make them ideal for use in water and heating systems. Moreover, the material’s excellent welding and hot-melt characteristics ensure a permanent, seamless connection, providing peace of mind for hidden plumbing projects.
In summary, PPR pipes are a reliable and cost-effective solution for home plumbing, especially when installed correctly. By following these purchasing and installation tips, you can ensure a durable and leak-free system. Don’t forget to double-check everything with your supplier and verify the quality of materials before proceeding with the installation.
