Anyone who knows any basic plumber instincts knows backflow is a no-good-very-bad situation. Not to mention, potentially dangerous.
For those of you who don’t know, backflow is the reversal of “bad” water or other substances (read: pesticides, sewage) through a cross-connection and into the piping of a public water system or consumer’s potable, or “safe”, water system, polluting the water in that system.
Backflow into a public water system can contaminate that water and make it unusable and undrinkable. This is generally caused by a sudden change in water pressure; however, this can be prevented with a reputable plumber, like St. Matthews Plumbing and proper equipment.
How does Backflow Happen?
Throughout our water supply systems, water is generally maintained at a specific pressure to provide sufficient water flow from the tap, shower or other fixture. Water pressure can change drastically due to water main bursts, frozen pipes or an unexpectedly high demand on the water system, such as multiple open fire hydrants. When pressure is reduced in the pipe, it may allow contaminated water from the soil or other sources to be pulled into the public water system.
Preventing Backflow
It’s the water suppliers’ jobs to ensure all customers have safe, usable water for drinking, cooking and cleaning. Most water suppliers install a backflow preventer at the water service connection to each system that could pose a threat to the public water system. Generally, these include: fire protection systems, irrigation systems, medical facilities, classified or restricted areas, and premises exempt from the State Plumbing Code.
A specialized backflow preventer valve protects potable water from contamination or pollution due to backflow. This device is installed at strategic locations in which there is a potential risk of contaminated fluids entering the public water system. Backflow preventer valves require inspection and regular testing by a professional plumber. St. Matthews Plumbing can perform all testing and inspections of your backflow preventer valves.
How MSD Protects Homeowners from Backflow
Louisville’s Metropolitan Sewer District (MSD) offers two voluntary programs under the Plumbing Modification Program to reduce basement backups and remove improper connections to the sewer system. MSD offers this program usually at no charge to you for home owner’s to protect their homes and the community’s waterflow from untreated sewage. These programs assist property owners in preventing basement flooding, decreasing sewer system overflows to our drinking water and to improve water quality in Jefferson County. It is a free and voluntary program to homeowners who qualify and can save them more than $2,000.
