Backflow Preventer Inspection & Testing in Durham Region
A safe and dependable water supply starts with effective backflow prevention. At Caldwell Plumbing, we provide professional testing, repairs, and installation services across Durham Region to protect your drinking water from contamination.
What is Water Backflow and Why It’s a Risk
Backflow happens when water reverses direction in your plumbing system, allowing contaminated water to enter the clean supply. This can happen due to sudden changes in water pressure, such as a water main break or heavy water usage nearby.
Contaminants from irrigation lines, industrial systems, or even household hoses can make their way into the water you drink, cook with, and use every day.
How Backflow Prevention Protects Your Water Supply
A backflow preventer valve allows water to flow in only one direction. When installed and maintained properly, it’s your first line of defence against cross-contamination.
