The quality of water pipes in AD is still good.

As a new type of water pipe material, AD water pipe has unique advantages. It can be used as both a cold water pipe and a hot water pipe. It is becoming a popular material because of its non-toxicity, light weight, pressure resistance and corrosion resistance.

PPR pipes are not only suitable for cold water pipes, but also for hot water pipes and even pure drinking water pipes. There is also hot melting technology at the joint of water pipes, and the pipes are completely fused together. Therefore, once the installation and pressure test pass, it will not age and leak like aluminum-plastic pipes, and the water pipes will not scale, rust and leak, so it is a green water supply material.

So in general, the quality of water pipes in AD is still very good.
