International Association of Plumbing and Mechanical Officials



Call to Order

The meeting was called to order at 12:01 PM on Thursday May 18, 2006 at Ricky’s Restaurant in San Leandro, CA. by Marty Cooper, Chapter Chairman, of the Central California Chapter of IAPMO.


Marty Cooper, Chapter Chairman, welcomed the 22 members to the meeting and our guest speaker Mr. Gene Sheffield of Local 38. Self-introductions followed general networking by the attendees.

Chapter Officers present were Marty Cooper, David Ledda, Sarah Aguilar and Nathan Vasquez.

Committee Reports

Sarah Aguilar gave the Treasury Report. We had a brief discussion on our account history. Bob Adler spoke on the CBSC rescinding adoption of the 2003 UMC.

Old Business

The minutes from the meeting of April 20, 2005 were reviewed and accepted.

John Wagner spoke on the fire resistance of stone as per the 2003 Marble Institute of America.

Bob Adler spoke on the Website and Technical Committee Conference. The TC considered 6 Mechanical TIA’s and 3 from Plumbing. The emergency nature of the TIA refers to an inspector’s need for prescriptive and specific Code language, rather than general performance-based requirements, as is currently found in the NFPA 54 extracts. The TC voted to put in the combustion air proposal into Chapter 9 of the UMC. A proposal for conversion of gas was appropriated from NFPA 54 and inserted instead. The TC voted to restore language detailing requirements for electric water heaters into the 2003 & 2006 UPC. The TC voted to accept proposals concerning elevation of mechanical equipment in flood zones. Two of the proposals accepted by the TC – combustion air & electric water heaters – were submitted by Bob Adler.

Bob Adler also brought before the TC two separate issues. The first concerned alternate materials and methods, which the current code mandates approval by the AHJ if equivalency is demonstrated. Bob presented evidence to the TC that the intended language was to read the AHJ shall have authority to approve, thus indicating where the approval power lay. The IAPMO code coordinator (Lynne Simmick) has begun an investigation to determine if Bob’s allegations are correct, and if they are to see if the language change can be changed editorially instead of a long and difficult TIA process. The other issue raised concerned the inclusion of Horizontal Wet-venting; Bob believed that the TC had not previously passed the code change, but they claimed otherwise. In any case, the section does not belong under Vertical Wet-venting and it does require more explanatory language. The Committee developing the Illustrated Training Manual is currently considering how to best handle this concern.

New Business

Correspondence from Scott Denny of Frank Denny Plumbing Inc. concerning venting of sewage ejectors was distributed. The matter was tabled until both parties in question are present.



Break for Lunch


Gene Sheffield of UA Local 38 gave a presentation on Anti-Siphon, Spill-Resistant Vacuum Breakers. The new assemblies prevent backsiphonage of contaminated water back into the potable water supply, while reducing excessive spills during start-up, testing or operation. Gene informed the Chapter that the critical level of the Spill-Resistant Vacuum Breakers is at least 1" above the flood rim for factory installed assemblies & 6” for field installed assemblies. Gene also provided a history of how the critical level is determined with respect to backsiphonage.


The chapter would like to thank Dan Shea (Camera case) and Marty Cooper for the donations.



Chapter Chairman Marty Cooper adjourned the meeting at 1:30 PM.

Respectfully submitted by:

Nathan Vasquez
Central California Chapter Secretary
