Backflow Certification

No project is too small or too big for us

As a proud member of the BCWWA since 2007, JJM Mechanical Group is fully certified to install, test, and repair all makes and sizes of backflow prevention devices. We also provide comprehensive testing and recertification services to ensure your systems remain in top working order.

In addition to backflow services, we offer detailed hazard assessments and water management planning reports. All backflow prevention devices and related potable water fittings in British Columbia, including testable and non-testable devices and brass fittings, must meet lead-free requirements.
