Flawed Duct Proposal Disappears Along with IAPMO Councils

Filed in Codes and Regulations by on December 4, 2017 1 Comment

ductsThe International Association of Plumbing and Mechanical Officials (IAPMO) has decided not to approve a change to the Uniform Mechanical Code (UMC) that could have added at least $5,000 to the cost of a new home in the six states that adopt it.

The proposal would have limited the length of flex duct to five feet in residential applications in the 2018 edition of the UMC.

Just before announcing its decision, the IAPMO standards council notified members of both the mechanical and plumbing technical committees, which had been discussing the code change, that both committees had been dissolved. The council then gave notice that it had ruled the exception would remain as written in the 2015 UMC for the 2018 UMC.

Had the council removed the exception, the added cost to residential dwellings could have increased the cost of a new home by $5,000 and even $7,000 in the states that adopt the UMC. Builders would have been limited to using no more than five feet of flexible duct when installing HVAC systems in single-family, duplex, townhouse and multifamily residences.

While the decision is a victory for cost-effective home building and a credit to the efforts of HBA leaders in California, Nevada and the coalition formed to fight the removal of the exception, the councils’ decision to dissolve the committees does leave a number of questions unanswered: industry advocates wonder how the council will keep an appropriate balance as it seeks to reform the committies, and whether the UMC and its companion Uniform Plumbing Code will continue to be created by consensus bodies representing all views, including builders and contractors as well as manufacturers and labor interests.

IAPMO is seeking applications for both the plumbing and mechanical committees, and NAHB continues to monitor IAPMO’s progress. For additional information, contact Don Surrena.

    By changing from the International Association of Plumbing and Mechanical Officials has decided not to approve a change to the Uniform Mechanical Code (UMC) that could have added at least $5,000 to the cost of a new home. This is only making it more difficult for first time home owners. I really hope this is overturned.
