What is a Backflow Preventer?

Imagine you’re filling up a backyard kiddie pool or watering your garden when water suddenly flows backward into your plumbing system. Without a backflow preventer, that contaminated water could mix with your clean drinking supply.

A backflow preventer is like a security checkpoint for your water. It’s a mechanical device that makes sure water flows in only one direction: out of your faucets and into your drains.

How Do Backflow Preventers Work?

Backflow preventers are usually installed where a clean water supply meets potential contamination sources like irrigation systems or industrial equipment. These devices use a series of check valves, air gaps, or pressure relief valves to block reverse flow. Here’s the gist of how it works:

• Check valves act like one-way doors which allow water to flow forward but slam shut if the flow reverses.
• Air gaps, or physical spaces between your water supply and potential contaminants, prevent any direct connection between the two.
• Pressure relief mechanisms kick in when pressure imbalances threaten to push dirty water back into clean lines.

These are not only found on private properties. Dallas’s municipal water supply depends on these particularly in areas with high irrigation needs or industrial activity.

Signs Your Backflow Preventer May Need Help

Backflow preventers are reliable, but they’re not immune to wear and tear. Here are a few red flags that your device might not be functioning properly:

• Rusty or foul-tasting water.
• Weak water pressure.
• Whistling, gurgling, or clunking sounds near the backflow preventer.
• Puddles around your backflow preventer or dripping valves.

Address these warning signs with plumbers as soon as possible. Early action can save you from more extensive repairs – or even fines.

When to Replace Backflow Preventers

Backflow preventers typically last between 5 to 10 years depending on the type, usage, and local water quality. When it’s time for a new unit, prompt action is crucial. Here are some situations where replacement is likely necessary:

• Repeated Failures During Testing
• Severe Corrosion or Damage
• Older Than 10 Years Old
