How Does Backflow Happen?
In order for water to flow from your faucets, water pressure must be consistent. If there is an interruption or reduction in your water pressure, backflow happens. In other words, the flow of your water supply reverses, and as a result your water can become contaminated with bacteria, chemicals, and other harmful toxins.
Backflow devices prevent this from happening and keep your water safe for drinking. That’s why if your backflow preventer is not working properly, getting it repaired immediately by a trusted professional is essential.
How Often Should You Test?
How often do you need to test your backflow preventer?
- At the time of installation, and at least once a year after, your backflow device should be tested in order to ensure it is working according to code.
- Backflow preventers also need to be replaced every five years to keep them working efficiently.
- You can trust in Carroll Mechanical, Inc. for prompt and professional backflow testing. We prioritize your safety and comfort, and always work with your best interests in mind.
