One common question is whether a cleanout must be the first fitting in the stack. Here\u2019s what you need to know to pass your plumbing inspection in Virginia, based on the IPC (<a href=\"https:\/\/basc.pnnl.gov\/library\/international-plumbing-code-ipc\">International Plumbing Code<\/a>).<\/p>\n<p data-start=\"844\" data-end=\"912\"><strong data-start=\"844\" data-end=\"857\">Question:<\/strong> Do I need a cleanout as the first fitting in my stack?<\/p>\n<p data-start=\"914\" data-end=\"1359\"><strong data-start=\"914\" data-end=\"925\">Answer:<\/strong> <strong data-start=\"926\" data-end=\"995\">Yes, a cleanout should ideally be the first fitting in the stack.<\/strong> The purpose of the cleanout is to allow easy access for clearing blockages in the drain system. If the cleanout is placed too high, as in your case at 30&#8243; above the slab, it may not be compliant with IPC standards. Typically, the cleanout needs to be installed at or near the lowest point of the system, ideally at the base of the stack before any other fittings.<\/p>\n<p data-start=\"1361\" data-end=\"1391\"><strong data-start=\"1361\" data-end=\"1391\">Additional Considerations:<\/strong><\/p>\n<ul data-start=\"1392\" data-end=\"2129\">\n<li data-start=\"1392\" data-end=\"1629\">\n<p data-start=\"1394\" data-end=\"1629\"><strong data-start=\"1394\" data-end=\"1414\">Code Compliance:<\/strong> The IPC generally requires cleanouts to be installed at specific points to ensure they\u2019re easily accessible. Installing it 30\u201d above the slab may limit access and could potentially lead to issues during inspection.<\/p>\n<\/li>\n<li data-start=\"1633\" data-end=\"1929\">\n<p data-start=\"1635\" data-end=\"1929\"><strong data-start=\"1635\" data-end=\"1659\">Potential Solutions:<\/strong> If relocating the cleanout below the washing machine standpipe tee, ensure it&#8217;s positioned at the lowest point of the system, allowing for proper maintenance and compliance with the IPC. Always double-check your local Virginia regulations to ensure full compliance.<\/p>\n<\/li>\n<li data-start=\"1931\" data-end=\"2129\">\n<p data-start=\"1933\" data-end=\"2129\"><strong data-start=\"1933\" data-end=\"1963\">Consulting a Professional:<\/strong> If you&#8217;re unsure about the correct placement, consider consulting with a licensed plumber who can assess the system and ensure everything meets inspection standards.<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"2131\" data-end=\"2237\">For more tips on plumbing system setup and inspections, visit <a class=\"decorated-link\" href=\"https:\/\/plumbing101.i234.me\" target=\"_new\" rel=\"noopener\" data-start=\"2193\" data-end=\"2236\">Plumbing 101<\/a>.<\/p>\n<hr data-start=\"2239\" data-end=\"2242\" \/>\n<p data-start=\"2244\" data-end=\"2316\" data-is-last-node=\"\" data-is-only-node=\"\">I&#8217;m Chris Mayer, writing for <a class=\"decorated-link\" href=\"https:\/\/plumbing101.i234.me\" target=\"_new\" rel=\"noopener\" data-start=\"2272\" data-end=\"2315\">Plumbing 101<\/a>.<\/p>\n<p data-start=\"2244\" data-end=\"2316\" data-is-last-node=\"\" data-is-only-node=\"\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-560\" src=\"https:\/\/plumbing101.i234.me\/wordpress\/wp-content\/uploads\/2025\/11\/Do-I-Need-a-Cleanout-as-the-First-Fitting-in-a-Stack-200x300.png\" alt=\"Do I Need a Cleanout as the First Fitting in a Stack?\" width=\"200\" height=\"300\" srcset=\"https:\/\/plumbing101.i234.me\/wordpress\/wp-content\/uploads\/2025\/11\/Do-I-Need-a-Cleanout-as-the-First-Fitting-in-a-Stack-200x300.png 200w, https:\/\/plumbing101.i234.me\/wordpress\/wp-content\/uploads\/2025\/11\/Do-I-Need-a-Cleanout-as-the-First-Fitting-in-a-Stack-683x1024.png 683w, https:\/\/plumbing101.i234.me\/wordpress\/wp-content\/uploads\/2025\/11\/Do-I-Need-a-Cleanout-as-the-First-Fitting-in-a-Stack-768x1152.png 768w, https:\/\/plumbing101.i234.me\/wordpress\/wp-content\/uploads\/2025\/11\/Do-I-Need-a-Cleanout-as-the-First-Fitting-in-a-Stack.png 1024w\" sizes=\"auto, (max-width: 200px) 100vw, 200px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Do I Need a Cleanout as the First Fitting in a Stack?
