Annual backflow testing, certification and municipality report submission for commercial and multi-unit properties in Ajax. Licensed and insured. We handle the compliance paperwork.
Backflow is the unintended reversal of water flow through a cross-connection, where water that has been used or could be contaminated flows backward into the clean municipal water supply. This can occur when there is a sudden drop in supply pressure, such as during a main break or heavy demand event.
Ontario Regulation 170/03 and Durham Region municipal by-laws require any property with a cross-connection risk to install an approved backflow preventer and have it tested annually by a certified tester. The results must be submitted to the municipality. Mechora handles the full compliance cycle: testing, documentation and submission.
Ajax's mix of industrial corridors along Bayly Street and established residential subdivisions creates strong demand for backflow compliance. Food processing facilities, car washes and medical offices along the commercial strips are required to test annually.
