Behind the Inspection: How a $10 Tool Helps Keep Your Arizona Home Safe

When most people think of a home inspection, they imagine checking the roof, HVAC system, or plumbing. But at Checklist AZ, we know some of the most important insights come from a $10 tool — the humble outlet tester.

Yes, really.

Electrical safety starts at the outlet, and this small, inexpensive device helps us uncover everything from improper grounding to wiring issues that could pose a serious risk.

What Is an Outlet Tester — and Why Is It So Important?

A Simple Tool With Powerful Results

Outlet testers are small devices that plug directly into electrical outlets. They use a combination of lights to indicate:

  • Correct wiring
  • Open grounds
  • Reversed polarity
  • Open neutrals
  • Other unsafe conditions

At Checklist AZ, we always carry two testers. Why? Because even the best testers:

  • Can break from a small drop
  • May have burned-out bulbs that give false readings
  • Might mislead an inspector into thinking there’s a major problem (like an entire house being ungrounded), when it’s just the tester that’s faulty

Double-checking with a second tester ensures accuracy.

How We Go Beyond the State Standards

Minimum Standard vs. Our Standard

The state of Arizona requires home inspectors to test a “representative number” of outlets — often interpreted as one per room.

But at Checklist AZ, we test every accessible outlet.

That means:

  • We don’t move furniture like beds or dressers
  • But if an outlet is open and reachable — we’re testing it

This approach ensures:

  • No missed safety hazards
  • Better insights into wiring consistency
  • Peace of mind for buyers and homeowners

It’s Not Just About Plug and Test

Some assume testing outlets is as simple as inserting a tester and pressing the button — but there’s more to it.

We also:

  • Verify GFCIs are wired and tripping correctly
  • Check if the outlet cuts power to itself, especially with master GFCI receptacles and breakers
  • Ensure power is properly restored after reset

This helps us catch issues like:

  • GFCIs that appear to trip but don’t truly cut power
  • Outlets that have power but lack grounding
  • Circuits that have been poorly altered or extended

Outlet Issues Are More Common Than You Think

In Arizona homes — especially older ones or DIY-modified properties — we often find:

  • Ungrounded outlets
  • Reversed wiring
  • GFCIs that don’t function properly

Even newer homes sometimes have overlooked electrical flaws from rushed construction or missing inspections.

When you choose Checklist AZ, you’re not just getting a home inspection — you’re getting a team that checks the details others might miss.
