Ask A Code Question 

Asking a code question has been made easy by choosing any one of 3 methods listed:

  • Call and speak with our code representative at 1-800-201-0335. 
  • Request written clarification. Our Answers and Analysis Committees has been appointed to respond to all requests for clarification on any published IAPMO plumbing or mechanical code. You may submit your question online or download a PDF form (see the link below). Allow 30 days for a reply. 
  • Request a formal interpretation of ANSI codes (UPC and UMC). Please see the link below to download a PDF form or submit your request online. NOTE: It is imperative that you read the directions carefully prior to submitting your request. Due to procedural regulations, response time to formal interpretations on ANSI codes may range from 90 days to one year.
