Inspection of backflow preventers
After the installation of an anti-backflow device, the regulations in force require a mandatory annual inspection. Through this service, PLOMBERIE FLR will check the proper functioning of each Dar. Tests will be carried out on your entire plumbing installation.
If anomalies are detected during the inspection, our plumbers will replace or repair defective anti-backflow devices. We can travel to Montreal and several cities on the North Shore of Montreal, as well as Laval, Saint-Jérôme, Terrebonne, Saint-Eustache, etc.
