This will be a short episode, but a very important one.
Since we have people from around the world who listen to Hacker Public Radio, I cannot begin to speculate what your local building codes allow or prohibit. In the majority of states within the United States of America, a property owner can perform plumbing maintenance on their own residence. Otherwise you need to be a licensed plumber. That may not be true for all states, and there can be inspections required and sometimes even fines for code violations.
Rules also vary for where PEX can be installed, how and how frequently it must be supported, and whether the work must be inspected or whether it requires a permit.
The point of this section is to remind you to do your research to find out what the rules are in your specific region, and then be sure to follow them. When in doubt, consult a licensed plumber in your area.
If you have missed the previous episodes in this series, I encourage you to review them before continuing because they will provide valuable context around my plumbing adventures.
