One of the great things about pressing is that the technology is a quickly adaptable skill, that provides consistency among your crew of installers.

However, like any plumbing technique, there are tips and tricks that make it a little easier. We’ve collected some of the most useful insider knowledge about the ProPress system (some of which came from our customers) and are sharing it with you.


How to deburr a press fitting

Sometimes, pressing a ProPress fitting or valve can leave a sharp edge or burr behind on the hub of the fitting. This doesn’t affect the performance, but why leave something behind that might scratch someone or catch on a tool?

Getting rid of the burr doesn’t have to be hard. Simply move the press tool backward and forward. It releases the jaw and knocks off the burr.
