What is Backflow and How it Happens
Let’s understand how and why backflow happens in the first place. A “cross connection” is when your drinking water system is connected to something that is not meant for drinking, like dirty water or other substances. This connection creates a risk of contamination, which is what we call backflow.
There are two main ways backflow can occur: backsiphonage and backpressure.
Backsiphonage happens when there’s a sudden drop in water pressure, causing dirty substances to be pulled into the drinking water system. Backpressure, on the other hand, occurs when the pressure in a non-drinking water system is higher than in the drinking water system. This forces the drinking water to flow backward through the connection, allowing contaminants to enter. In both cases, backflow makes the drinking water unsafe.
To prevent backflow, we use backflow prevention devices. These devices are installed in the water lines and have special valves to stop dirty substances from flowing back into the drinking water supply. However, these devices can wear down over time and fail because they’re made of rubber, springs, and metal parts. That’s why it’s important to have a regular maintenance routine that includes backflow testing every year. When a backflow prevention device is installed, it needs to be tested and certified. The same applies after any repairs and at least once every year.
So, to keep your water safe, make sure to get backflow testing done regularly by a certified technician. It helps prevent contamination and ensures that your drinking water stays clean and healthy.
Remember, regular backflow testing is the key to maintaining the integrity of your plumbing system and safeguarding your water quality. Don’t delay—call us now to schedule your backflow testing appointment!
Who Needs Backflow Testing?
Any property with a cross-connection between the public water supply and a potential source of contamination is required to have backflow prevention.
In the Madison area, the Department of Natural Resources (DNR) and local municipal codes mandate that these systems be tested annually to ensure that “back-siphonage” or “back-pressure” doesn’t pull non-potable water into your drinking supply.
Residential Properties
While many standard homes don’t require an external assembly, you likely need professional testing if your property features:
- Irrigation & Sprinkler Systems: The most common reason for residential testing. These systems use chemicals and fertilizers that must be kept out of your home’s pipes.
- Swimming Pools & Hot Tubs: Any permanent filling line requires protection.
- Boiler Heating Systems: Water used for heating is often treated with chemicals and sits stagnant, making a backflow preventer essential.
- Private Wells: If your home is connected to both city water and a private well.
Commercial FAQs
The City of Madison has strict requirements for high-hazard and low-hazard commercial connections. Testing is mandatory for:
- Restaurants & Commercial Kitchens: Due to grease traps, dishwashers, and carbonators.
- Medical & Dental Offices: To prevent biohazards from entering the main line.
- Manufacturing Plants: Any facility using chemicals, dyes, or industrial cooling systems.
- Multi-Family Housing: Large apartment complexes or condos with dedicated fire suppression systems.
Backflow FAQs
Backflow testing should be done at least once a year as recommended by most plumbing codes and regulations. However, the frequency may vary depending on local requirements, the type of property (residential or commercial), and the specific backflow prevention devices installed.
Backflow testing should be performed by certified technicians who have received proper training and possess the necessary qualifications. These technicians have the knowledge and expertise to accurately test backflow prevention devices and ensure their compliance with regulations.
In most cases, there are no specific preparations required from the property owner. However, it’s important to ensure that the technician has easy access to the backflow prevention device and any relevant plumbing connections. Clearing the area around the device and providing necessary documentation or permits, if required, can help facilitate the testing process.
Backflow testing is often a legal requirement mandated by local plumbing codes and regulations. It is important to check with local authorities or consult a certified technician to determine the specific requirements applicable to your area.
