Backflow Testing in Longview and Cowlitz County
Backflow occurs when water flows backward into your plumbing system, potentially contaminating it with harmful substances. Regular backflow testing is essential for maintaining the safety of your water supply, ensuring your plumbing operates at peak efficiency under all conditions.
While backflow is, of course, an unpleasant inconvenience, it also presents a great risk by exposing you and your family to harmful bacteria and other contaminants that don’t belong in your home. The last thing you want is to put the health and well-being of your loved ones in danger, so don’t put it off until the last minute.
Changes in water pressure, discolored water, and a foul odor from your taps are all classic signs that you need backflow testing. If you notice any of these, act fast.
Our backflow prevention services involve the following:
- Comprehensive Inspection: We check your backflow prevention devices for proper operation.
- Pressure Testing: We assess the water pressure to verify that it meets safety standards.
- Detailed Reporting: We provide a full breakdown of our findings and recommendations.
