Hello, this is President Yasui, running a one-man company that mainly inspects high-pressure gas equipment.
I’m currently staying in a regional city, at a hot spring inn located about 10 kilometers from the city center.
The food is delicious, and I’m very satisfied.
It’s a wonderful experience that offers a different kind of Japanese lodging compared to a hotel.
If you get the chance, I recommend staying at a ryokan too. :)
There was a problem with a liquid regulating valve, and I received a request for maintenance.
I conducted a thorough inspection before disassembly to understand the situation.
Despite carefully disassembling, servicing, and restoring it, the issue remained unchanged...
There was one internal part that made me go, “Hmm? Could this be it?”
The customer, having seen how meticulously I assembled everything, seemed to be giving up.
But I asked if I could disassemble it once more, and they agreed.
I reassembled it while air-blowing the flow paths, but the symptoms didn’t change.
So, I started flushing each component upstream, one by one.
Even after air-blowing all the visible areas, nothing changed.
I was unsure whether it would help, but after reassembling everything again, the issue was resolved.
The customer was relieved too.
Even when I asked the manufacturer, they only gave a vague explanation for the cause.
But when you're facing a problem right in front of you, it’s hard to accept that kind of explanation.
Even when thinking it through logically, I couldn’t believe that would cause such a severe issue.
I had carefully assembled everything, yet the symptoms didn’t improve at all, and I almost gave up.
But I had only tried once.
Some might say, “We don’t know the cause. Nothing will change even if we keep going.”
But it felt way too early to say that.
Most likely, there was a foreign object lodged in a narrow passage.
In the end, it may seem like a simple thing.
But I believe that was the true cause.
Observe what’s right in front of you, form a hypothesis like, “If this is the cause, then this should work,” and try until results are achieved.
If it doesn’t work, try whatever comes to mind.
If the root cause is unclear, you just have to try different approaches.
Since customers are paying for the service, you must keep at it until they’re satisfied.
This time, I’m glad I got results.
But I think it's important to stay persistent and not change the goal halfway.
I’ll never forget this particular issue—it’s now part of my experience.
Troubleshooting problems like this helps me grow, and I deeply felt that during this repair job.
See you again!
