Friday, 9:20 PM — The Call
March 15, 2024. I was wrapping up paperwork from a job in Houston when my phone rang. I coordinate emergency plumbing and water-system service for commercial properties and RV parks — mostly in Texas, sometimes Oklahoma. Night calls aren't unusual, but this one had a different tone.
It was a long-time client, the manager of a 120-site RV park in the Hill Country. Their main well pump had been cycling on and off for days. Now it had quit entirely. No water for the whole park. Peak season bookings were two weeks out.
I asked the usual first questions: How long has this been going on? What have you noticed? Any pressure changes?
He said the pressure gauge had been acting "weird" for about a week. They figured it was nothing.
I grabbed my toolkit and hit the road.
Missing that Friday-night call window would have meant mobile water tanks, refunded bookings, and a very unhappy owner. Not to mention a bill that would have probably run into five figures.
Midnight — What the Well Pump Actually Needed
I got to the park around 11:40 PM. The maintenance shed was unlocked — good, because I needed the panel access. Here's what I found:
The pressure switch contacts were scorched. The stabilizer was clogged with sediment buildup. The pump itself? Still running, but the motor was pulling more amps than spec. It was a matter of when, not if, it would burn out.
Here's the thing that got me. None of this was sudden. The cycling was a symptom. The scorched contacts were a symptom. Someone — anyone — could have caught this with a five-minute weekly check.
I replaced the pressure switch with a spare I carry in the truck. Cleaned out the stabilizer. In hindsight, I wish I'd had a replacement stabilizer on hand — I had to pull one off a service truck that was parked at the shop. That cost me an extra forty minutes.
Around 1:30 AM, the well pump was back online. Pressure stabilized. Water was flowing to the park again.
That should have been the end of it.
1:45 AM — The Leak Nobody Noticed
I was walking back to my truck when I noticed water pooling near the pool equipment pad. It was the pool pump — a 1.5 HP Everbilt unit the park had installed about three years earlier. The base was wet. Not soaked, but wet enough that I crouched down and put a hand on it.
The maintenance guy — he'd stayed late to help — told me it had been "slightly leaking" for a couple of weeks. They figured it was no big deal since the pool wasn't open yet.
I told him something that I've learned the hard way: small leaks in shaft seals don't stay small. They go from drip to failure fast, and they almost always pick the worst possible moment. Like the first weekend of peak season when every site is booked.
The next morning, I called around for a replacement seal kit and shaft seal. Not every retailer stocks Everbilt pool pump parts in-store, but Home Depot had what I needed — the shaft seal ran about $18. If I'd waited until the pump actually failed, we'd be looking at a full pump replacement, probably $200 plus labor, plus whatever refunds the park would have to issue if the pool was down during a fully booked weekend.
While I was at it, I checked the park's other equipment:
- Pressure washer nozzle: completely worn out. The spray pattern was so wide it was basically a garden hose. A new nozzle costs under $15. They were using it to clean concrete pads and wondering why it took twice as long as usual.
- Air compressor: there was a slow leak at the manifold fitting. They were losing maybe 30% of its output without realizing. A $4 fitting, 10 minutes to install.
- Angle grinder: this one made me stop. They had a buffing wheel mounted on it. I'm not going to name the brand, but it was a standard 4.5-inch angle grinder. Can you put a buffing wheel on an angle grinder? In a pinch, yes — but it's not what it's designed for. The RPM range is different, the arbor fit is often loose, and the guards don't always cover enough. If you're doing light polishing, fine. If you're doing anything heavy, you're asking for a wheel to grab and send the tool flying.
I mentioned all of this to the park manager on Saturday morning. He didn't push back — he asked me how they could have missed all of it.
Saturday Morning — The Checklist Conversation
That question led to a longer conversation than I expected. I told him what I've come to believe after eight years and maybe 600 service calls: it's tempting to think equipment failures are just bad luck. But most of the time, there's a trail of small warnings that nobody was tracking.
We sat down and built a 15-point seasonal startup checklist. Here are the most important items:
- Check pressure switches for scorch marks — if the contacts look burnt, replace before the season. A $25 part that saves a $400 pump.
- Inspect seals and gaskets for moisture — a dry hand on a wet base is the cheapest diagnostic you'll ever do.
- Test pressure washer nozzles — spray them against a hard surface. If the pattern is wider than a quarter, replace them.
- Check air compressor fittings with soapy water — bubbles mean leaks, and a 30% loss in output often goes unnoticed.
- Verify that power tools are used as designed — buffing wheels on angle grinders, wire wheels on drills, cut-off wheels on underpowered tools. It's tempting to improvise, but that's how injuries happen.
- Log gauge readings weekly — one line on a clipboard. A week's worth of data catches a hundred-dollar problem before it becomes a thousand-dollar one.
He asked me if I remembered the exact cost of the parts. Honestly? I don't. I want to say around $150 total for the switch, seal kit, nozzle, and fitting — but don't quote me on that. The point isn't the exact dollar amount. The point is that the cost of the parts was less than what the park would have lost in a single weekend of pool closures.
July 2024 — The Check Paid Off
Fast-forward to the middle of peak season. During a routine mid-season inspection, we caught a pressure switch that was sticking. Not failed — just sticking. We replaced it on the spot.
That's a $25 part and 20 minutes of labor. The alternative — a well pump failure in July with every site booked — would have been mobile water, emergency service fees, and likely a few one-star reviews. Probably around $2,000 in total cost and a lot of stress.
I'll be honest: I didn't always work this way. For my first couple of years on the job, I was pure reaction — fix it when it breaks, move on to the next call. It took me about 150 service calls before I understood that the savviest contractors aren't the ones who fix things fast. They're the ones who keep things from breaking in the first place.
That's not a glamorous answer. It doesn't make for a great story at the supply house. But it's true.
One more thing — this is for anyone ordering replacement parts online: standard shipping through USPS typically runs 2–5 business days depending on distance. If your peak season is two weeks out, that window is tighter than you think. Don't wait until the pump is dead to order the seal kit.
The Bottom Line
I'm not saying every equipment failure is preventable. Some things are going to break no matter how careful you are. But most of the emergency calls I go on have a week or two of small warnings that went unread.
Five minutes of verification beats five days of correction. And when you're running a facility, that's not just a saying — it's the difference between an expensive repair and a normal Tuesday.
If you take one thing from this: put a clipboard in your maintenance shed. Write down three gauge readings every Monday. Look at them on Friday. That one habit would have caught every issue at that RV park weeks before it became an emergency.
