Backflow Prevention
Wastewater flowing back through your pipes can expose your business to a wide range of serious concerns. These issues extend beyond unpleasant odors or discoloration and can include health risks for staff and customers, as well as financial and legal consequences that may disrupt or even permanently shut down your operations.
If you suspect a backflow issue, don’t assume it will resolve on its own. Contact MJ Fahy & Sons to schedule a thorough inspection and professional commercial plumbing repair to protect your water supply and your business.
What Is Backflow?
Backflow occurs when water flows through plumbing pipes in the opposite direction of its intended path. This typically results from changes in water pressure, such as a sudden drop or surge, or when non-potable water enters a potable water supply.
Because backflow can introduce bacteria, chemicals, fertilizers and other hazardous substances into your building’s water system, most cities and towns require businesses to install backflow prevention devices at key connection points. For reference, water pressure in commercial buildings should generally remain between 40 and 60 PSI.
Backflow issues often stem from:
- Changes in water pressure along your plumbing system, which may occur after you install a new boiler, pump or commercial appliance.
- Negative water pressure, also known as back-siphonage, caused by excessive water usage or damaged plumbing.
Common Causes of Backflow
If you notice foul-smelling or dark-colored water pooling in sinks, toilets or floor drains, your plumbing system may be experiencing a backflow problem. Common causes include:
- Recent plumbing upgrades, such as rerouted pipes, new fixtures or appliances, or added units in a commercial or residential complex.
- Excessive water demand from equipment or high-usage systems.
- Connections to devices that use non-potable water, such as irrigation or fire suppression systems.
- An aging, damaged or malfunctioning backflow prevention device.
- Outdated plumbing that no longer meets current building codes, particularly systems that fail to properly separate potable and non-potable water.
Backflow Testing and Repairs
If you suspect a backflow issue, MJ Fahy & Sons can help. We begin with professional backflow testing and a comprehensive inspection of your commercial plumbing system. This includes evaluating water pressure levels and ensuring backflow valves and prevention devices are operating correctly.
Based on our findings, we may recommend one or more of the following solutions:
- Installing an air gap between the water supply and critical connection points
- Replacing or installing a new backflow prevention device to better regulate pressure and reduce siphonage risks.
- Scheduling annual backflow testing and routine maintenance to ensure ongoing compliance and protection.
Why Backflow Testing Is Important
Backflow can immediately contaminate your water supply, creating serious health risks for employees, customers and the surrounding community. Upgrading your backflow prevention system and maintaining regular testing:
- Helps protect clean, drinkable water for your business and the public.
- Identifies pressure and performance issues before they escalate.
- Reduces the risk of cross-contamination, costly repairs and forced closures.
- Ensures compliance with local plumbing codes and regulations.
- Helps prevent fines, penalties and legal issues.
- Is often required to maintain commercial insurance coverage.
