The Standing Committee on Building and Plumbing Services began its new code cycle this past May for the 2010 Code editions. The following provides highlights of the SBCPS activities:
 
I)  The Committee has approved changes for the NPC 2005 and Part 9 of the NBC 2005 relating to Hot Water Delivery in Buildings for public review. The changes are:
 a) Temperature of hot water delivered in all buildings to tubs, showers and lavatories should not exceed 49C to deal with the potential for scalding;

b) Water in re-circulating loops shall be maintained at not less than 55C. The re-circulating system can operate continuously or intermittently. This is to reduce the probability of growth of legionella bacteria in the piping system;

c) Controls for storage type service water heaters shall be set to provide a water storage temperature of not less than 60C. This is to reduce the probability of growth of legionella bacteria in the piping system;

d) Revisions have been proposed to Article 9.31.6.1 in Part 9 of the NBC to refer to the NPC for hot water supply requirements;

e) Appendix information has been added to provide additional background on the requirements and to help understand the options to meet the specified code requirements; 
II) The committee has created a task group to deal with water pipe sizing;
 
III) Proposals with dealing with "trade waste systems" have been drafted;
 
IV) Proposals dealing with harmonized CSA B125/ASME 112.18.2 have been posted for public review at the www.nationalcodes.ca website.
