The Uni-Bell company produces technical publications and many different patent applications on their website, as well as many other resources related to piping systems. This is all because of an ongoing research process that Uni-Bell is under. All the information on the website has expanded with the help of a lot of independent surveys and experiments so that they can now supply answers and information to many different questions one might have regarding materials such as pipe connectors, water pumps, and full plumbing integration systems.
