It details critical installation constraints, including trap arm length limitations, downstream water closet connection requirements, and proper fixture discharge configurations. The text provides essential sizing criteria for both dry vents and wet vents, emphasizing that wet vents must be at least 2 inches for 4 fixture units (DFU) or less, and 3 inches for systems exceeding 5 DFU. These guidelines, referenced under M.R. Chapter 4714, Section 908.2, ensure compliance with standards enforced by the Department of Labor and Industry. The illustrations offer visual schematics for public and private restroom configurations, depicting specific DFU loads, vent sizing, and appropriate fitting connections to maintain effective drainage and ventilation in plumbing systems. This content serves as a foundational guide for plumbing contractors and inspectors to verify system safety and adherence to state mechanical and plumbing codes.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/horizontal-wet-venting-plumbing-code-guidelines/656523/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/horizontal-wet-venting-plumbing-code-guidelines/656523.png","ImageObject",300,407,{"name":92,"@type":93},"Cipher","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-25",true,{"@type":102,"interactionType":103,"userInteractionCount":29},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the minimum size required for a wet vent based on the fixture unit load?","Question",{"text":112,"@type":113},"A wet vent must be at least 2 inches in size for 4 DFU or less, and not less than 3 inches in size for 5 DFU or more.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"Where must the water closet drain be connected in a horizontal wet vent system?",{"text":117,"@type":113},"The water closet fixture drain connection must be located downstream of all other fixture drain connections to the horizontal wet vent.",{"name":119,"@type":110,"acceptedAnswer":120},"How should the dry vent be sized for a horizontal wet vent system?",{"text":121,"@type":113},"The dry vent must be sized based on the total fixture units (DFU) discharging into the wet vent system.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},656523,1792969056,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":29,"category_name":30,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":29,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":8,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":129,"read_time":81},687208528416,"https://ap-avatar.wpscdn.com/davatar_9964176cb1d06d4a9deccf72a44ae3dc","A BATHROOM GROUP LOCATED ON THE SAME FLOOR LEVEL MAY BE VENTED BY A HORIZONTAL WET VENT  \n-THE LENGTH OF THE TRAP ARM MUST NOT EXCEED THE LIMITS OF TABLE 1002.2.  \n一THE WATER CLOSET FIXTURE DRAIN CONNECTION MUST BE DOWNSTREAM OF ALL FIXTURE DRAIN CONNECTIONS TO THE HORIZONTAL  \nWET VENT.  \n-ONLY ONE WET-VENTED FIXTURE DRAIN SHALL DISCHARGE UPSTREAM OF THE DRY-VENTED FIXTURE DRAIN CONNECTION.  \n-ADDITIONAL FIXTURES MUST DSCHARGE DOWNSTREAM OF THE WET VENT SYSTEM AND THEY MUST BE CONVENTIONALLY VENTED.  \n一THE DRY VENT MUST BE SIZED BASED ON THE TOTAL FIXTURE UNITS DISCHARGING INTO THE WET VENT.  \n一THE WET VENT MUST BE SIZED BASED ON THE FIXTURE UNIT DISCHARGE INTO THE WET VENT.THE WET VENT MUST BE AT LEAST  \n2 INCHES IN SIZE FOR 4 DFU OR LESS,AND NOT LESS THAN 3 INCHES IN SIZE FOR 5 DFU OR MORE.  \n# Horizontal Wet Venting\n\nM.R.Chapter 4714,Section 908.2  \n## DEPARTMENT OF\n\nLABOR AND INDUSTRY  \nPhone:(651)284-5063  \ndli.mn.gov/business/plumbing-contractors/alternates-checklists-and-other-information","cbCailsep04BxGQ3","https://ap.wps.com/l/cbCailsep04BxGQ3","pdf",1505746,"English","# Horizontal Wet Venting\n## Installation Requirements\n## Sizing Specifications","[{\"question\":\"What is the minimum size required for a wet vent based on the fixture unit load?\",\"answer\":\"A wet vent must be at least 2 inches in size for 4 DFU or less, and not less than 3 inches in size for 5 DFU or more.\"},{\"question\":\"Where must the water closet drain be connected in a horizontal wet vent system?\",\"answer\":\"The water closet fixture drain connection must be located downstream of all other fixture drain connections to the horizontal wet vent.\"},{\"question\":\"How should the dry vent be sized for a horizontal wet vent system?\",\"answer\":\"The dry vent must be sized based on the total fixture units (DFU) discharging into the wet vent system.\"}]","Horizontal Wet Venting - Plumbing Code Guidelines | PDF"]
