The plug is there for cleaning. It is not a take-off point.<\/p>\n<h2>What Code Expects (In Plain English)<\/h2>\n<ul>\n<li>Keep a drip leg at each appliance that needs one.<\/li>\n<li>Do not branch from the trap or its cap.<\/li>\n<li>Run your new line from a proper tee <em>before<\/em> the trap.<\/li>\n<li>Use approved gas piping and fittings for the whole run.<\/li>\n<li>Leak test and pressure test the system after work.<\/li>\n<\/ul>\n<h2>Better, Safer Plan for Your 17-Foot Run<\/h2>\n<ol>\n<li>Shut off gas and verify the line is safe to work on.<\/li>\n<li>Cut in a tee on the supply line <em>upstream<\/em> of the drip leg.<\/li>\n<li>Pipe the new branch to the laundry location with the right supports.<\/li>\n<li>Add a shutoff valve, union, and connector at the appliance.<\/li>\n<li>Install a new drip leg at the appliance as required.<\/li>\n<li>Perform code-compliant testing and inspection.<\/li>\n<\/ol>\n<h2>Sizing and Testing Tips<\/h2>\n<p>Gas lines must be sized for total BTU load and length. A 17-foot branch may need upsizing depending on what else the line serves. Always follow your local code and manufacturer instructions. A licensed pro should perform the pressure test and document results for inspection.<\/p>\n<h2>Helpful Resources<\/h2>\n<ul>\n<li><a href=\"https:\/\/codes.iccsafe.org\" target=\"_blank\" rel=\"noopener\">International Fuel Gas Code (IFGC) \u2013 Read-only access<\/a><\/li>\n<li><a href=\"https:\/\/call811.com\" target=\"_blank\" rel=\"noopener\">Call 811 \u2013 Utility locate and safety info<\/a><\/li>\n<li><a href=\"https:\/\/www.energy.gov\/energysaver\" target=\"_blank\" rel=\"noopener\">U.S. DOE Energy Saver \u2013 Natural Gas basics<\/a><\/li>\n<\/ul>\n<h2>Q &amp; A<\/h2>\n<p><strong>Q:<\/strong> Can I legally remove the plug in the drip leg and run my new line from there?<\/p>\n<p><strong>A:<\/strong> <strong>No. That cap is for cleaning.
