How Are Costco Refrigeration and Condensation Falls Proven?

A cooler near the puddle is a starting point. You still have to prove where the water came from, how long it was there, and what the store knew.

What is the short answer?

You need to prove the source, the location, how long the water was there, notice, and the store's response.

Isn't it obvious the cooler did it?

It feels obvious when you're the one sitting on the cold concrete next to a dairy case with water under your hip. That's exactly why the store's adjuster will slow down. A wet floor in front of a walk-in cooler could be condensation. It could also be mop water, rain off someone's umbrella, or a gallon of milk that split in a cart two minutes earlier.

A cooler nearby is a theory. The rest of this guide is about turning it into proof.

What happened when a shopper blamed a leaky roof?

The Texas Supreme Court answered a very similar argument in April 2026. In H-E-B, LP v. Peterson, a shopper slipped on a clear puddle in a toy aisle and looked up to see water dripping from a rafter. The store had been dealing with numerous roof leaks during a remodel. Her companion first said he saw drips every 10 or 15 seconds, then took it back.

She lost anyway. The court said the earlier leaks were in other parts of the store, so they said nothing about this puddle. A drip from the rafter pointed to a cause, not to when the puddle formed. And the size of the puddle didn't let a jury guess how long it had been there. The court reinstated summary judgment for H-E-B.

Put a reach-in freezer where that rafter was, and you have the problem every condensation case has to solve.

Where else could the water have come from?

Before anyone settles on the cooler, rule the others in or out:

• defrost water or a clogged drain line (drain maintenance tickets)
• mopping (the cleaning log and the worker who mopped)
• rain tracked in (weather for that hour and the route from the doors)
• a shopper's drink or a cracked jug (video, or a container left nearby)

Then pin the unit down. Get its asset number, measure from the door seal to the puddle, check which way the floor slopes, and note any mat the store had already put down there.

Does a history of leaks prove notice?

Not by itself. Here's how the usual facts rank after Peterson:

So the question for the service company isn't whether this cooler has ever leaked. It's what was wrong with this cooler that morning, and what time the technician left.

What does a dispute look like?

Here is a hypothetical example, not an actual case. The morning ticket on case 17 reads "drain clogged, ice buildup." Somebody mops near it at ten past noon. The camera first catches a shine on the floor at 12:32, and at 12:40 a member's feet go out from under her by the cooler door. The defense has its own version: a shopper dropped a drink at 12:38.

Was it the drain, the mop or the drink? The technician's close-out time says whether the drain was even still clogged. Stepping through the 12:30 to 12:40 frames one at a time tells water from glare, since water spreads and glare doesn't. The mopper can say what he used and whether he set out a sign. And a refrigeration tech can say whether drain water could travel six feet to her spot at all.

Can the records be used in court?

Yes, if they're authenticated and the judge finds them relevant. Rule 401 of the Texas Rules of Evidence asks whether an earlier event is similar enough to matter. Rule 403 lets the judge keep it out if it would confuse or mislead the jury. Rule 901 requires proof that the maintenance record and the video are what they claim to be.

What should you do in the first week?

1. Photograph the floor, the unit and its asset tag, from where you were standing.
2. Keep the shoes you were wearing, unwashed.
3. Ask the warehouse, in writing, to keep the video and the service records for that unit.
4. Write down the names of the workers who came over and anything they said about the cooler.

Frequently asked questions

I fell right next to a freezer. Isn't that enough?

No. You still need proof that water from that unit got to that spot.

A technician fixed the cooler the next morning. Does that prove it was leaking?

Not automatically. The earlier condition can still be proved other ways, like prior tickets or a witness.

All I saw was clear liquid. Was it condensation?

Maybe. Water from a dropped bottle looks the same, so let the evidence pick the source.

Will I need an expert?

Often, to explain how water could get from the unit to where you fell.

How long will the store keep the video?

It depends on the system, and many overwrite on a schedule. Ask for it right away.
