Frequently Asked Questions
When do I use a PEX plug?
Use a plug to cap a line for a future fixture, close off an abandoned branch, or seal a system for pressure testing before the walls are closed up.
Is a plugged PEX line reopenable?
You would cut the plugged end off to reopen the line, then add a new fitting. Leave a little extra pipe if you anticipate extending it later.
