Orange Gunk on a Tankless Water Heater Almost Killed My Deal (Spoiler: It Was Just Sweaty Pipes)
Written by Justin Scott | Bend, Oregon Real Estate Agent | justinbend.com
Look, I've seen some wild stuff derail real estate deals. Buyers backing out over carpet color. Sellers are losing their minds over a lowball offer. But watching a deal nearly implode over what turned out to be a sweaty foam collar on an exhaust pipe? That was a new one—even for me.
Let me tell you a story about panic, perspective, and why having a real estate agent who actually understands how houses work might just save your sanity (and your bank account).
The Setup: A Perfectly Reasonable Contract
I was representing the sellers on a nice home here in Bend. The buyers came in with a solid offer and included this very reasonable clause: "Sellers to do no repairs unless the total in aggregate exceeds $2,500."
Smart buyers. Smart language. This keeps everyone from nitpicking over minor issues while still protecting against major problems.
The buyers ordered their home inspection (which every smart buyer absolutely should do). Inspections help you understand exactly what's going on with the house—especially ensuring those expensive mechanical systems are working properly when you take ownership.
So far, so good. Everything's cruising along nicely...
Then the Inspector Saw The Orange Stuff
The home inspector spotted orange-ish corrosion sitting on top of the tankless water heater. He red-flagged it. Wrote it up in the report with appropriately ominous language. Did his job exactly as he should have.
The buyers' agent shared the report with their clients.
And that's when things got... spicy.
The Panic Sets In
The buyers saw "CORROSION" and "RED FLAG" in the same sentence and immediately jumped to DEFCON 1.
Their minds went straight to worst-case scenarios:
"The whole system is failing!"
"This is going to need replacing!"
"What else is wrong that we don't know about?!"
"This is a disaster!"
They started painting mental pictures of $5,000 tankless water heater replacements, failing furnaces, and the whole mechanical system teetering on the edge of catastrophe.
The deal that had been smooth sailing? Suddenly dead in the water.
Here's the thing: I totally get it. When you're making the biggest purchase of your life and a professional inspector flags something as a concern, your brain naturally assumes the worst. You're not a plumber. You're not an HVAC tech. You're just someone trying to buy a house without getting burned.
But this is exactly where having an agent who actually understands home systems becomes worth their weight in gold.
Enter: One Slightly Nerdy Real Estate Agent (That's Me)
Instead of immediately panicking alongside everyone else or getting defensive (because, remember, I'm representing the sellers here), I did something radical:
I called a licensed plumber.
Not to argue with the inspection report. Not to downplay the concern. But to get a proper diagnostic from someone who actually specializes in tankless water heating systems.
The plumber came out, did his thing, and here's what he found:
The "Disaster" Was Actually... Condensation
Ready for this?
That terrifying orange corrosion that nearly torpedoed my deal?
It was condensation from a foam insulation collar on the exhaust pipe.
Let me break this down:
Someone (probably with good intentions) had wrapped the exhaust pipe with foam insulation
The foam was creating condensation—basically, the pipe was sweating
That condensation was dripping onto the top of the tankless unit
Bend has notoriously hard water (thanks, Central Oregon minerals!)
When the water dried, it left behind orange mineral deposits
Voilà: scary-looking "corrosion"
The fix?
Remove the completely unnecessary foam collar from the exhaust pipe. The unit sits in a climate-controlled garage. It doesn't need insulation. The foam was literally creating a problem where none existed.
Cost of the fix: $0 (just pull off the foam)
Time required: About 90 seconds
Amount of panic generated: Approximately one metric ton
Why This Matters (And Why I'm Telling You This Story)
Here's what I want you to take away from this:
1. Home Inspectors Are Doing Their Job (And That's Good)
The inspector wasn't wrong to flag this. He saw corrosion. He reported it. That's literally what we pay them to do. Home inspectors are generalists—they spot potential issues and recommend further evaluation by specialists.
They're not the bad guys here. They're your first line of defense.
2. Not Everything That Looks Scary Actually IS Scary
Orange crusty stuff on your water heater? Yeah, that looks concerning. But "looks concerning" and "actually dangerous" are two very different things.
This is why you don't stop at the inspection report. You bring in specialists who can actually diagnose what's happening.
3. Panic Is Expensive
If we'd let panic drive the bus, here's what could have happened:
Buyers demand a new tankless water heater: $4,000-5,000
Or they walk away entirely, restarting their home search: Priceless (and not in a good way)
Sellers lose a solid buyer over a foam collar: Also not ideal
Instead, we spent $150 on a plumber diagnostic and solved the issue for literally zero dollars.
4. Your Agent's Knowledge Actually Matters
Anyone can unlock doors and fill out contracts. But when technical issues pop up (and they will), you want an agent who:
✅ Understands how mechanical systems actually work
✅ Knows when to bring in specialists vs. when to negotiate
✅ Can separate real problems from scary-looking non-problems
✅ Keeps everyone calm and focused on solutions
✅ Protects the deal without compromising safety or integrity
I'm not saying you need an agent with a mechanical engineering degree. But having someone who's invested time understanding how houses actually function? That's worth its weight in gold (or orange corrosion, as the case may be).
What YOU Should Do If This Happens to You
If You're Buying:
DON'T: Immediately assume the worst and demand replacements
DO: Request a diagnostic from a licensed specialist
DON'T: Let fear drive your decisions
DO: Get actual repair estimates and timelines
DON'T: Walk away without understanding what's really happening
DO: Work with your agent to investigate thoroughly
If You're Selling:
DON'T: Get defensive when issues come up
DO: Be proactive about getting proper diagnostics
DON'T: Dismiss buyer concerns as overreactions
DO: Provide documentation and professional assessments
DON'T: Ignore obvious issues, hoping they won't be noticed
DO: Address things upfront (or at least understand what's happening)
If You're a Real Estate Agent:
DON'T: Wing it when technical issues arise
DO: Invest time learning about home systems
DON'T: Let clients spiral into panic mode
DO: Be the calm, knowledgeable voice that keeps deals on track
The Happy Ending
We got the plumber's report. I shared it with the buyer's agent. The buyers' agent shared it with their clients. Everyone took a collective breath and realized we'd been stressing over condensation and minerals.
The foam collar came off. The "corrosion" stopped appearing. The deal closed on time.
My sellers were happy. The buyers got a great house. And I got a fantastic story about why real estate agents should probably understand a bit more about plumbing than the average bear.
The Moral of the Story
Not everything that appears to be a disaster is, in fact, a disaster.
Sometimes it's just a sweaty pipe with a foam identity crisis.
But you won't know which is which unless you:
Stay calm
Bring in qualified professionals
Work with people who actually understand what they're looking at
And maybe—just maybe—don't wrap exhaust pipes in foam collars when they're sitting in climate-controlled garages. Just a thought.

The Bottom Line: Knowledge Is Your Superpower
The most successful homebuyers and sellers aren't the ones who never encounter problems – they're the ones who know how to respond when orange gunk appears on their water heater at the worst possible moment.
Your dream home might have a few quirks. (Spoiler alert: they all do.) The question isn't whether issues will pop up during inspection—they almost always do—but whether you have someone in your corner who can tell the difference between a foam collar having an identity crisis and an actual mechanical disaster.
Because at the end of the day, this isn't about finding a perfect house – it's about understanding the one you're buying well enough to move forward with confidence.
And when that inspection report comes back with red flags and technical jargon that makes your eyes glaze over? Having an agent who genuinely understands what's happening (and can explain it without the panic) is worth its weight in... well, orange mineral deposits.
Your dream home is out there. It might even have some suspicious-looking corrosion on the tankless water heater. But with the right team, a licensed plumber on speed dial, and an agent who knows that not all scary-looking things are actually scary? You're going to be just fine.
