IAPMO Standards Council Issues TIAs UPC‐001‐12 and UPC‐011‐09

The IAPMO Standards Council on Aug. 29 issued Tentative Interim Amendments affecting the 2009 and 2012 editions of the Uniform Plumbing Code® (UPC).

TIAs UPC‐001‐12 and UPC‐011‐09 revise and/or add new language to Chapters 2 and 9 of the 2012 UPC and 2009 UPC, respectively, amending and adding new definitions to Chapter 2 and revising Section 908.2 Horizontal Wet Venting for a Bathroom Group in Chapter 9.

These TIAs identify specific requirements that must be met for the installation of horizontal wet venting. Specific requirements include:
• Limits installations to one bathroom group.
• Provisions are now applicable to both private and public use.
• Urinals may no longer be vented by a horizontal wet vent.

To examine TIAs UPC‐001‐12 and UPC‐011‐09 in their entirety, and/or any other TIAs affecting the Uniform Codes,

TIAs are proposals based on the determination of an emergency nature requiring prompt action to amend code that contains an error or omission that was overlooked during the regular code development process, contains a conflict within the document or with another IAPMO document, or to correct a hazard, promote an advancement in safeguarding the public or provide an opportunity to correct an adverse impact on a product or method of installation.
