Most condominium mechanical engineers believe that based on the industry experience with Kitec piping, premature failure may occur in the future. This presents the problem of uncertainty for property owners, which can bring stress and worry about safety, structural stability, disclosure requirements, and property values.
The rate of failure of the Kitec pipes will certainly increase over time as the condition of the piping and fittings worsens.
The problem presents itself in two ways:
1. The brass fittings fail. Here is an article about the Kitec system brass fittings: https://canadianlaw.wordpress.com/category/insurance/subrogation/
2. The pipe itself can rupture, mostly around the fittings, but anywhere pressure builds up and where water temperature is very high. Learn how the pipe has been failing here. (** includes video**) http://www.cbc.ca/news/canada/windsor/faulty-pipes-cause-headaches-for-homeowners-1.1000605
