Lar-Mex also has a preventative maintenance division working on a regular basis to ensure that our customers’ equipment is maintained as per manufacturers’ specifications.


A cross connection is a direct or indirect connection between the drinking water system and a private plumbing system. In order to keep the City’s water distribution system free from possible contamination, the main water supply must be isolated from the private system by stalling a backflow prevention device at or near the water meter (called premises isolation). The device prevents liquids or contaminants from entering into the municipal drinking water system.

To comply with the program, you may be required to:

• Conduct a CCC survey as requested by the Municipality
• Submit survey results to the Municipality
• Install the appropriate backflow prevention device as instructed
• Test the device annually or more frequently as appropriate
• Submit device testing results to the Municipality
• Maintain the backflow prevention device in working condition at all times
