Backflow Preventer Maintenance Made Easy: When to Test, What to Check, and When to Call a Pro

Backflow preventers are one of the most important — yet often overlooked — components of your plumbing system. Whether you’re a homeowner or run a small business, these devices are your first line of defense against contaminated water flowing back into your clean water supply.

In this guide, we’ll break down:

• ✅ When to test your backflow preventer

• 🔍 What you can safely inspect yourself

• 📞 When it’s time to call in the professionals

Let’s dive in.

🕒 When Should You Test Your Backflow Preventer?

Routine testing is more than just a good idea — in many locations, it’s a legal requirement. Here’s a quick breakdown of how often you should be checking your device:

🔍 What You Can Check Yourself

You don’t need specialized tools to do a quick visual inspection. Here’s what you can safely check on your own:

✅ 1. Look for Leaks

Check around the valve body and connections. Any signs of dripping or pooled water can signal a problem.

✅ 2. Inspect for Corrosion or Wear

Rust, greenish buildup, or damaged parts might suggest aging or wear. Don’t ignore early signs — small issues can lead to major failures.

✅ 3. Ensure Valves Are Working

Open and close the shut-off valves to ensure they’re moving freely. Stuck or stiff valves might need professional service.

✅ 4. Watch for Pressure Problems

Low water pressure in your faucets or appliances may point to a blocked or malfunctioning backflow preventer.

🚫 What You Should NOT Do Yourself

While it’s great to perform basic checks, never attempt to open or disassemble a backflow preventer. Here’s why:

• Internal testing requires certified equipment.

• Tampering can void warranties or cause system damage.

• You may violate local codes by attempting unauthorized repairs.

  ⚠️ Always leave testing and repairs to licensed professionals who can properly diagnose and certify the system.

👨‍🔧 When to Call a Pro

You should contact a certified backflow technician if you notice:

• Consistent or unexplained leaks

• Corrosion or visible damage

• Changes in water taste, color, or pressure

• A missed or failed annual test

Also, you should schedule routine testing or certification if:

• You’ve installed a new irrigation system

• You’re due for your annual compliance test

• You’ve recently had plumbing work done

💡 Tip: Backflow testing only takes about 20–30 minutes when done by a pro — and can save you from expensive repairs or fines.
