The CF Chinook Centre owners chose to centralize the disposal of FOG waste by running pipes from each restaurant to a single location. Jonathan Suisham, Mechanical Sales, IPEX worked with the engineering firm Smith & Andersen, to specify the Drain-Guard™ Double Containment piping system for this project.

In April IPEX Sales Representative, Patrick Bergeron, visited the warehouse and met with site foreman, Grant Thomas. Thomas mentioned that the MJ Grey™ Mechanical Couplings were making it much easier to do the 8” and 10” install with the height and space challenges in the warehouse.
