PPR pipe is better. However, the scope of application and characteristics are different. If it is only used for the transformation of cold water pipes, etc., then in terms of quality, PPR pipes must be better. But one thing everyone should pay attention to is that there are many PPR tubes that say: No surface installation. The non-exposed installation here refers to the installation outdoors under sunlight. If the PPR pipe is installed outdoors, it must be replaced every two years, otherwise bacteria will breed and the service life will be greatly shortened. Not as good as PVC pipes.
