The name "Plumber" has its origins in the ancient Latin word, Plumbum, meaning "lead." In Medieval times, the word Plumber was used to identify "workers of lead." Given recent changes to the Ontario Building Code, it appears that we may have to change what we call our Plumbers!
Changes to the maximum allowable amounts of lead in plumbing products took effect January 1, 2014 in Ontario. The changes require lead levels to be reduced from 8 to 0.25 percent for fittings intended for use for human consumption through drinking or cooking. Examples of these products are pipes, fittings and Backflow Preventers that serve potable water systems. An Ontario Minister ruled that the low lead requirement be included in the 2012 Ontario Building Code and are expected to be included in the National Plumbing Code in 2014. The rest of Canada's Provinces are working towards including this requirement in their respective Provincial Building Codes.
The transition rule allows that any building permit applied for before Jan 1, 2014 still follows the 2006 Ontario Building Code, but construction will have to start within 6 months from when the permit is issued. Permits issued after January 1, 2014 will have to comply with the 2012 Ontario Building Code and the new low lead requirements
So, after a millennia, Plumbers may have to change their name as they will no longer be "workers of lead." The Latin word for water is Aqua... perhaps calling our Plumbers, "workers of water," or Aquarians may be more fitting ?
