Secrets Inside Your Well Pump. How Does A Deep Well Pump Work? FarmCraft101

My well pump was replaced recently, so I do a complete teardown and diagnosis on the old pump, including going through how it works. There is one mystery component that I'm not sure about. Is it a temperature sensor? It might be a lightning arrester. Do you know? Leave a comment.

Thank you for taking both the cost hit of the new submersible pump + the time to disassemble and explain the components of a submersible pump. This has value for many families. Well done.

It's probably a triac. When power is applied the bi-metallic strip is in contact so the triac energizes the start winding. As the motor spins up it generates heat which in turn causes the strip to bend and opens the switch. This bypasses the start winding and the motor continues to run on the main winding alone.

I run a well pump farm. We usually get them in as Aquarium or more often fountain pumps and then feed them until they are self priming and are ready to move to the deep well pump pool. Most often we'll sell them off at around 120 volts, but some we let go up to 240.

Your pump appears to have suffered from pulmonary embolism, which is brought on by filling your pool several times in a row, or throwing a washing machine party. I suggest only feeding your new pump clean watts and avoid any future water parties or late night bucket filling adventures. Pumps work best between 6am and after sunset right before dusk unless you can sneak up on them during noon when they are napping.

The part you were inquiring about is a simple proximity sensor. It's looking for other pumps in the general area. Most people think of the well pump as a solitary creature, but they have been known to pair up.

The knowledge and work it took to invent and produce these mechanical gadgets amaze me.

Nice to see the curiosity, tried to show the kid but really no interest in just learning how things work. To me that is the most fun also. Being on city water we can only experience the deep well pump teardown from guys like you that take the time to film. Thank you sincerely. Lawson di Ransom Canyon

I had to replace a pump motor that was a 2012 unit. The well guys said that could be part of the problem, and if I wanted to save them coming back in the foreseeable future that I should just replace it while they were there. They had one on the truck, a little more horse power, and went with new install.
You always wonder about such things, but you have my decision easier to bare. Thanks. Love the fact that you breezed through all the tedious part of screw removal and other time consumers. Good job.

Came across your video looking up info on well pumps.
Good to know I'm not the only one who saves things you somehow know you'll use later down the line. 👍🏼

My dad had a similar attitude to yours. Well, so far as finding parts and materials to save. Although he was a city boy, he was the first generation city hoy. My granddad grew up in the country and probably still had the understanding broken things weren’t junk, especially living in the country in the early 1900’s. But my dad wasn’t as interested in how things worked. That’s me...also with the salvage gene.

We've got very corrosive salty water on our farm, and we've had to change out a few of those submersible pumps over the years. The pump side was still perfectly fine, its mostly plastic impeller parts, we've learned to just buy a replacement motor and couple it to the existing pump ellement.

You did a good job with your video - it got to the facts without being boring.

[HappilyHomicidalHooligan]

3:50 That's a Thermal Overload switch. It cuts power to the motor if the Temperature gets to high preventing damage to the motor.
Overheating in well pumps is usually caused by either a bad bearing (starting to seize up) or debris jamming the pump impeller.

Wow. I am so glad I found this. Building a new house and first time I've ever had a well. My curiosity has been through the roof and thanks to you I can sleep without wondering: "how does that skinny pump work down there?" Cheers!

[lfmtube]

Very well done and instructive video! I just change my old (220 Volts-3 phase and 3.5hp) deep well pump by a new one in Argentina. The old one it lasts about 10 years of use for the irrigation. I think its burned because some high voltage peak. Thanks to your video, I learned what's inside and how it works. Thanks!

[topgundk]

I love that your first reaktion when a thing shoot out of the motor, was to look into where it just shot a thing out from :D

[hotflashfoto]

Knowledge is Power.

You should do a Saturday morning TV show. I'd watch it for sure!

[sushilgharat]

Thanks for the video..
I faced problem in my submersible pump.(1hp)
I checked resistance in motor found ok.
Further checked found pump electric panel card fault.
So replaced the card now works fine..

[notfound]

Wow, that was great. Loved the mystery ejecting sequence. Everything I take apart, ever since I was 10 years old taught me to expect something under tension to come flying out. It was satisfying to see that rule still holds and I'm well over 60. Anyway, I'll be paying someone to pull my submersible, though I do damn well want to do it myself. "Damn well" ... ha ha get it?

[MichelleRubery-ei]

Oh dear. Mine has also been in since about 1972 on the old property i have. So i guess i can’t repair myself. Thank you. Saved me from wasting time.

[walt]

great video ! I always wondered what was inside one of these. I've gone through 4 pumps in 30 years living in the Sierra foothills. Enjoy

The rubber and plastic seals cause most of the failures with the pumps. Sand in the bottom of the well can scour the impeller rendering it useless. Even with the long-term wear issues we replaced windmills with submersibles and have not looked back. The maintenance on the submersible electric is nothing like the replacing of leathers and the annual maintenance on older windmills. Plus, the old Aeromotor windmills were worth a good deal of money, people wanted them for their aesthetics which offset the cost of the new elelctric pumps.
