Hey there, water warriors! I'm Corbin Moyer, your friendly neighborhood backflow expert from 1-A Services. Today, we're diving into the wild world of cross-connections and backflow incidents. Grab your floaties and let's wade through some real-life tales that highlight the importance of keeping our water flowing in the right direction.
What’s the Big Deal with Backflow?
Before we plunge into the stories, let's get our feet wet with some basics.
Backflow is the unwanted reversal of water flow in a plumbing system, leading to contamination of clean water with, well, not-so-clean stuff. This usually happens due to:
Backpressure: When the pressure in your system exceeds the supply pressure.
Backsiphonage: When there's a sudden drop in supply pressure, causing a vacuum that sucks contaminants back into the clean water.
A cross-connection is any actual or potential link between potable (drinkable) water and a source of contamination. Think of it as the mischievous cousin that invites trouble to the family reunion.
Now, let’s dive into some splashy stories where things went awry.
Case 1: The Salty Surprise at a Fast-Food Joint
In Norfolk, Virginia, customers at a renowned fast-food restaurant got an unexpected twist in their beverages—a salty one. The culprit? A nearby ship-repair facility had a fire protection system using high-pressure seawater. Due to a faulty backflow preventer (which had been replaced with a makeshift sleeve), the salty seawater was pushed into the public water system, reaching the restaurant's soda fountains.

Lesson Learned: Always ensure backflow preventers are properly installed and maintained. A DIY fix might save time but could lead to a salty disaster.
Case 2: School’s Out—Due to Antifreeze?
In Bowling Green, Kentucky, an elementary school faced a slippery situation when students started feeling ill after drinking water that tasted off. The investigation revealed that propylene glycol (a common antifreeze) from the HVAC system had backflowed into the school's drinking water due to a faulty connection.

Lesson Learned: Regular inspections and proper backflow prevention devices are crucial, especially in places where our kiddos spend their days.
Case 3: X-Ray Vision... into Contaminated Water
A clinic in North Carolina reported a bitter taste and chemical odor in their water. The diagnosis? An unprotected garden hose used to fill an X-ray developer tank had created a cross-connection. Negative pressure caused the chemicals to be siphoned back into the potable water supply.

Lesson Learned: Never underestimate the power of a garden hose to wreak havoc. Always use hose bibb vacuum breakers and keep hose ends out of contaminants.
Case 4: Pool Party Foul
After two children fell ill with bacterial infections, it was discovered that a garden hose submerged in their algae-filled swimming pool had caused the problem. The hose created a cross-connection, allowing contaminated pool water to siphon back into the home's drinking supply.
(IDS Water)
Lesson Learned: Filling your pool? Keep that hose out of the water, and ensure your chlorination system is up to snuff.
Case 5: A Pesticide Cocktail in New Jersey
In Marlboro Township, New Jersey, an extermination contractor was diluting the insecticide chlordane using a submerged hose—creating an illegal cross-connection. A simultaneous water main break caused a negative pressure, siphoning the entire insecticide drum into the town’s water system.

Lesson Learned: Always use proper backflow prevention devices when dealing with hazardous chemicals. A little negligence can poison an entire community.
How to Keep Your Water Flowing the Right Way
Now that we've splashed through these tales, here are some tips to keep your water safe and sound:
Install Backflow Preventers: Devices like check valves and vacuum breakers can stop contaminants from reversing into your clean water.
