I used to work for others and sell water and electricity materials, including water pipes. I have sold many brands, such as Jinde, Liansu, Pegasus, Tian Li, Benefit, Goody and so on. On the whole, Jinde's is good. It's just a little expensive. Oh, personally, Liansu is not bad, not very expensive, so it's no problem to sell so much.

Of course, there are many brands, so you must buy genuine products. Some brands have fakes.

Also, you should hire a professional plumber. No matter how good the water pipe is, it is afraid of problems if it is not installed well, especially PPR pipe must be installed. I hope I can help you and wish you a happy new year!
