How do I make sure that my piping system is clean ?
Maintaining a clean piping system is probably the biggest reason for a contractor to install with Reflok connectors.
For "standard" brazed piping connections, the installing contractor should ALWAYS run a nitrogen purge to push the oxygen out of the pipe and prevent the black oxidation ("soot") from forming on the inside of the pipe.
Since Reflok connections eliminate the brazing process the need for a nitrogen purge is also removed. Reflok piping is supplied with plugged ends to ensure the piping stays clean and dry prior to installation.
