Things to Know About Well Pumps

I was thrilled that Burgess Pump & Well had a technician at my house in an hour. After troubleshooting the segment from the pump controller to the well it seemed clear the problem was down the well. He lifted the well pump and motor out in 20 foot sections. Pull 20 feet up unscrew that section pull up another 20 feet.

The well is 250 feet deep. The pump was at 120 feet. The pump part was okay. The motor was toast. Whoever put in the well cheaped out to get a lower bid. The pump was rated for 1 1/2 horsepower; the motor was 3 horsepower. The extra load of running the motor at too  high a load burned it up a few months out of warranty.

Anyway, the cost of replacing it is about $5200. At least when we list it, "New well pump under warranty."  American Home Shield will cover $1500 of it. I expect authorization tomorrow and new pump ssme day or next. I am getting tired of not showering, doing dishes, laundry, and turning flushing into a complex reloading process.

AI May Destroy Teaching But It Is Going to Revolutionize Many Fields

4/30/26 Science:

If you walk into an emergency room (ER) in 10 years, you’ll encounter a new type of caregiver: an artificial intelligence (AI) system designed to get you a diagnosis faster and help your care team make more informed decisions. While you sit in the waiting room, you’ll be hooked up to a blood pressure cuff that’s constantly and autonomously monitored. All the while, an AI agent will be listening in while you and your doctor talk about your symptoms, ready to flag any mistakes your physician makes or suggest next steps.

This vision of AI-assisted emergency health care may soon be reality. In a new study, researchers show that a type of AI known as a large language model (LLM) often outperformed physicians at diagnosing complex and potentially life-threatening conditions, including decreased blood flow to the heart, even in the fast-moving stages of real ER care when information is limited, they report today in Science. In early ER cases, the model identified the correct or a very close diagnosis in about 67% of cases, compared with roughly 50% to 55% for physicians. And the technology is only getting better.

“Evaluating AI in medicine demands both depth and breadth across different clinical tasks and settings,” and these authors were able to incorporate both in this study, says Shreya Johri, a computer scientist at the Dana-Farber Cancer Institute who was uninvolved with the new research. Still, she notes, wide adoption of these AI systems in health care will hinge on knowing the contexts in which they’re most reliable.

Fine with me as long as the LLMs are not filled with antiracism crap which denies that there are genuine physiological differences, at least at the means between races. 

Faster, no exhausted ER doctors at the end of a long shift, less fear of lawsuits. For some specialty medical care, shorter wait times and larger supply.

This is also an earlier version of OpenAI. Everything is getting better and faster.

After repeated calls, our home warranty company has authorized us to get a local vendor to come and do an estimate.

When the Communists Come to Power...

Yes. They will pass by her mansion because she showed her solidarity with the people! $12 million means she could invest it in municipal bonds of her state and enjoy $480,000 a year income exempt from federal and state income tax. Can you live comfortably on $40,000 a month. Let's see her try 

History

 It is an article of faith that the enormous loss of Indian life after the Spanish arrived was because the Indians had no immunities to measles, smallpox, and a bunch of other diseases that had been killing people in the Old World long enough that our gene pool had selected the weak ones out. One of the student papers referenced a CDC article that I found fascinating:

Abstract

The native population collapse in 16th century Mexico was a demographic catastrophe with one of the highest death rates in history. Recently developed tree-ring evidence has allowed the levels of precipitation to be reconstructed for north central Mexico, adding to the growing body of epidemiologic evidence and indicating that the 1545 and 1576 epidemics of cocoliztli (Nahuatl for "pest”) were indigenous hemorrhagic fevers transmitted by rodent hosts and aggravated by extreme drought conditions.

Now, this was not entirely without Spanish involvement:

These infections appear to have been aggravated by the extreme climatic conditions of the time and by the poor living conditions and harsh treatment of the native people under the encomienda system of New Spain. The Mexican natives in the encomienda system were treated as virtual slaves, were poorly fed and clothed, and were greatly overworked as farm and mine laborers. This harsh treatment appears to have left them particularly vulnerable to epidemic disease.

Warming Up

Time to pull out the Hawaiian shirts. The next few nights will be 70 degrees when I roll out the telescope at 10:00 

Not Much Activity; Well Pump Failed

I have been busy solving other problems.  Our well pump (or at least part of the supporting electrical system) has failed.  American Home Shield, our home warranty company, has performed well on the only other problem we have had but that was a dishwasher, which is nice but hardly an emergency. Not having water in the house for cooking, laundry, dishwasher, and especially toilets is another matter. 

Our first service request yesterday is apparently working through the system. I called this morning to emphasize the emergency nature of this.  We are promised a service provider call today. 

I confess to being rather spoiled by past experience. The house I had built above Horseshoe Bend was never a problem. I designed it with self-sufficiency in mind although I was not truly off-grid. The backup generator ran off the LP gas tank.  It powered the well pump, the pressurization pump, the furnace and A/C and the kitchen.  When Idaho Power dropped the ball, as they often did, it had little impact.  We had a 1000 gallon tank.  I have no idea how much gas the backup generator used but we never ran out. 

The well pumped water into a 1000 gallon cistern which had enough elevation to give us 5 psi. This was enough that when the pressurization pump failed once, we still had enough water to hand wash dishes and flush toilets.  Also, 1000 gallons takes a long time for two people to use.

I miss that house. 

Anyway, after going through a lot of bottled drinking water to flush toilets, we suddenly realized that the canal water for the sprinklers, as gross as it, will flush toilets just fine. My wife labeled some of our empty drinking water bottles Toilet.

Whoever put together our sprinklers did something a little clever. Our Red Lion sprinkler pump in most applications needs to be primed every spring. The air trapped in it, will hold a bubble that the incoming low pressure canal water can not push through.  The system we have uses pipe with a faucet to allow air to escape. 

When the air finishes bleeding through, irrigation water comes out, even if the pump is not running. I hooked up a hose to that faucet.  Irrigation system gravity pressure let me fill up those jugs in a hurry.
