At Twin Peaks Plumbing, Heating & Gas, we’re proud to offer quality backflow testing to the residents of Ladysmith, BC. Backflow prevention devices are designed to keep wastewater out of your fresh water supply. They are one-way valves that allow water to flow out of your home but not back in. They also can keep community water safe and free of parasites and other dangerous contaminants. Backflow devices have the potential to fail and need to be fixed as soon as you notice a problem. Contaminated water can make you sick. Having a backflow repair professional take care of the details of the job can ensure that everything is done right the first time.
