R.C. Worst & Co., Inc. does the motor need lubricant
@@jamalpolius9093 yes, water.
I love these videos, can you do a series on older wells, and jet pump wells also? I’m having nonstop issues with an old well on its last leg and would be nice to see something just like you’ve done here about diagnosis and troubles with older or even outdated wells people may need to get by on until they can afford a new install.
@Julian Kairo congrats you just gave whoever’s insta password to someone who’s gonna sell it to a database or go in right behind you and steal all their info! Next time just ask for the password.
@Julian Kairo Consequences of hacking an Instagram account
Not only Instagram but hacking any social media account is a crime. It is considered an invasion of privacy. Your account will not only get banned for violating policies, but you will get arrested as well and might be in jail for at least six months.
Hacking others account is a wrong practice. But what if you are hacking your account. Is it legal? Is it right? For the sake of the article, let’s say you hacked your own Instagram account. Since you are hacking your own Instagram account, the only thing you will be going in jail for will be for violating company policies. Many countries do not practice such strict internet laws, and these might be overlooked. The incident itself will probably go unnoticed as you won’t be reporting the crime that you committed.
Thank you very, very much. Your presentation saved me a lot of money. You are great!!!!!!!
Glad we could help!
Thank You! Most helpful - new subscriber.
Thanks Richard!
You are a very good presenter Mr Worst - in fact change your name to Mr Best !
Thanks, you help a lot!!!
Indeed, thanks for taking the time to make this video, my motor is over 120M deep so it's good to be able to troubleshoot it before pulling it out 👍
good explanation
Informative...
Good job thanks
sweet jesus thank you brother! checked my control box and pump with your steps both checked out fine, did a continuity test on all the wires from the house to the pump, no continuity on the yellow! found the break! will be fixed by tomorrow for another $20cdn on top of the 40 I spent on making the puller!!
Nice Job! Happy we could help :)
Nice one thank
Thanks the explanation is very clear..l have problems with my well submarine pump.. that is the pump is stuck ..no rotation .I changed the capacitor no change..
I learned a lot,,thank's
Glad it was helpful!
Thank you sir
You betcha, thanks for watching!
Thanks. I would have liked it better if you hadnt spent so much time talking about the meters and straight to the testing procedures. But it helped to verify that I did all the tests i should have on my friends pump motor.
Thanks for watching!
Thanks alot, i fixed one of those pump how long should I start to service this motor
Question ?
2 wire pumps have a internal start capacitor vs 3 wire. And the pump with the open winding was a bad start winding so the pump could run but can't start. Thanks
loved the video been out at the welll with my Ipad bought a new meter but your video doesn't show the settings you used thanks
You are my new Worst friend
thanks...... شكرا
Bro good video
Appreciate it
What if the pump starts, shoots water out for a second, then stops? Then it tries to restart, shoots water again and stops. The cycle repeats.
I haven’t measured the currents yet. Have ya measured the resistance either yet, I ordered a meter and it will arrive on Tuesday.
Question, my motor insulation resistance drops after 24 hours , what are the possible reason or cause for it to happen.
You said to factor in the depth of the well when checking the windings. I can’t find the chart you were talking about can you help? I have a 4” 5hp pump.
The instructions are on page 47 of this document: www.rcworst.com/Shared/content/mfr/franklin_electric/docs/franklinsubmersiblemotorguide2010.pdf
So is 12.1 bad? On a 1hp 3 wire? On 200ohm setting?
For deep well (250feet) 5HP 8 stage 3 phase submersible Motor pump under 220v what is the pump impeller size and specifications to give out the water at high pressure and is it impeller size proportional to high pressure water out
Test the resistance of submersible pump 7.5 kW cooling system water gave the following values between the first and second and the first and third 1.7 ohms second and the third and 0.8 oum. When the operation gave 50 amps for about 5 minutes and did not work What are the reasons for the cause of the holidays and how to avoid this,
I have a 3 in well case. Had hard time trying to prime deep well jet pump. Couldnt get packard assembly and leathers to seal properly. Since its a 3 in case what submerisable pump would you use. Your video says 4" pump so does that mean 4 " well
Grundfos makes a 3 inch pump. I know of no other.
Is there a way to tell what horsepower the pump is without pulling the pump out of the casing? I just purchased a property that has a deep well but idk what size pump is there. The control box isn't there so I can't reference that.
You can take an amp reading and compare it to the values on pg. 13 of the aim manual: www.rcworst.com/Shared/content/mfr/franklin_electric/docs/franklinsubmersiblemotorguide2010.pdf
R.C. Worst & Co., Inc. Thank you! I checked it yesterday and came up with 2.8 ohms on the main wires and 10.3 on the start wires so that putse right at a 1 HP pump. Thanks again!
Ho can you tell if the pump was hit by lightning test.?
The only tests you can do are the ones we performed in this video. Often, lightning strikes will fry the capacitors or relay in the control box though. I would check them first.
Hello... my motor is not listed ..type 2343636010 S1 Y 380 V 2A, i have only 3 wires. Is this motot type listed in another pdf? Thank you.
Does measuring black to red tell you anything?
Black to red will give you a total resistance of all the windings. It will be the sum of yellow to red and yellow to black.
Thanks Sir I am Prakash Krantisen From India i have some Franklin & Red Jacket STP (Petrol & Oil ) i want spares parts of Thise Motors can u send services center links please healp me
my motor was hot its above ground just stopped working the power switch isnt sparking or anything
Watch our video on that: ruclips.net/video/D1IoZ7lOOdI/видео.html
I looooove your videos! I'm testing the ohm reading on my 1/2 hp motor. Can you tell me what the ohm reading should be? I have 6.2 between black and yellow and 19.5 between red and yellow.
115V or 230V?
230 volt
Where can I get an AIM manual Sir?
Here's a link to the PDF: www.rcworst.com/Shared/content/mfr/franklin_electric/docs/franklinsubmersiblemotorguide2010.pdf
Please sezest me How I get water deft 350ft 1/2" to drink water
Hi is it possible to have you go over material list for my new well? It’s dug and well log is at hand, 440ft deep, static water at 330 ft, yield 25 + gpm, 4” well is located in Corning California, empty lot planning on building home. At the moment, just plan on getting water out to nearby water storage tank of 2500 gallon, located down hill about 100 ft from well, a drop of 30’ in lifting water I guess. I plan on having a generator to pump water out to storage tank, so pressure switch is not needed. I need help in deciding a submersible pump preferably 1.5 hp, wire size( 10/3 ?), piping (blue polyethylene 500 ft roll, 1.25”?). I never have a well of this depth but am curious and want to install pump myself for saving money, but also wanting to know well better for maintenance in the future. I also plan to build home myself. Understand this may not be right venue to reach professional advice, just wanted to try.
We sure can help! Give us a call: 855.329.4519
Spanish
Thanks a lot sir
Thanks for watching!
Thank you. i will check this. I have a new pump acting funny, I think I have bad new wires.
Thanks a lot it really helped me.
Wife called to say there's no water pressure. Came home, smelled a fishy smell and noticed oil stains below the pump controller. Pulled controller and found start cap very hot and had vented.
I have 11 ohms from red to yellow, but open from red to black and yellow to black. Is this what overheated the start cap?
I have single phase submersible pump my question is three cable coming out from the water supposed to read continuity together I mean brown,blue and black
My well pump guy added screen to the bottom of my pump, is that a good idea? Is that recommended? What happens when screen gets dirty / clog ? Will it Damage the pump ??
Helped quite a bit, nice video thank you
Me ayudan mucho tus videos pra resolver algunas dudas, aquí es difícil conseguir los manuales de usuario.
Te lo escribo en español para que veas hasta dónde llega esta magnífica ayuda.
Saludos desde panamá.
Would be nice for a quick check for shorts or opens on the motor windings without worrying about the 1.1, 1.7, etc readings
What kind of check valve should I install four or five on a 140 ft deep well? I want to evenly space them inside the well casing. I see spring type and swing type.
Worthless info
Fantastic video. 🥳 Thank you.
Thanking you very much. May God Almighty bless you.

Great information. Thank you. My problem is I have air sputtering from all my faucets. The flow of water volume and pressures are fine but spits air every 10 seconds or so.
well explained troubleshooting
You can't test the start winding circuit on a 2 wire pump without pulling the pump out of the well and isolating the start circuit. That's a big advantage for the 3 wire version - where the cap is on the surface in a control box. You could determine a shorted capacitor if your ohmmeter is accurate enough as it would read less than what the run winding should read (ex: 2 ohm run winding with 7 ohm start winding would read 1.6 ohms). An open capacitor would not be detectable as you would only read the run winding resistance. A grounded start winding should be indicated as well but not an open start winding.

Contractors don't want to repair submersible pumps (only jet pumps get repaired) but contractors also don't want to install jet pumps. Can I replace a bad motor on a high end 4" submersible pump with a generic lower cost motor?
I am measuring at the we'll head and am reading 2 M ohms from both lines to ground and from the neutral to the ground. Does this mean there is a short to ground and the pump is bad ? Pump has stopped working and fuse keeps tripping
I been a pump installer all my life literally since I was a baby because my dad couldn't afford baby sitters. I of coarse use digital multimeters but back then my dad used analogues and when doing this test he would always stab the ground with a screw driver and conect the ohm meter to it and if the needle maxed out he knew it was shorted to ground lol.
My well is 535 ft deep. The well pump Motor is a 4 wire (often called a 3 wire) or 1.5 hp. There is 10 wire coming out of the cap, and runs to the Control Box within 2 feet away. Finally, there is above ground UF-B Wire, Direct Earth Burial Cable wire that runs 184 ft to the power pole. I want to relocate the Control box to 130 feet away from the well Cap, and still 54 feet away from the power pole using buried conduit. Can I use 10 AWG wire and connect it to the 4 leads I make at the well cap?
Thank you in advance for any advice and your video's, that are a great help!!
#10 wire is only good for 480' total run at that horsepower. You should be using size #8
Why would you do a video with a $10 meter?
So an average homeowner can follow along
@@RCworstwater Thanks
Next time use a better Metter.
I replaced the well pump that was a 3/4 hp with a 1/2 hp pump control box and pressure switch are for a 3/4 hp they both tested good according to the instruction videos of your but we'll ran for one day and quit could it be because of the fact I put the 1/2 hp pump in it ? I béen without water for two weeks now and have animals to water and I'm at a lose of what could be the problem please any ideas would be greatly appreciated
Will contact you tomorrow thanks
What if the motor runs okay but the outer cassing gets hot or after it runs for some time the overload trips.
Hi Chris. If I am installing or servicing a pump other than a Franklin, where would I find the information to troubleshoot similar to the pages you referenced in the AIM book? Does each manufacturer produce a book similar to that? Are there specs that come in the literature of each new pump?
Franklin is the only company to be taken seriously. Other companies are hit and miss. Us pump installers really don't even care what brand the pump is as long as it has a franklin motor. Honestly though you don't need to know the actual ohms or factory coil specs. You would just use the ohms to see if there is a short as he shows. Is there a problem with you well?
Great video
Could you advise why the power voltage drops when I turn on the submersible pump? Even if I am using off grid generator, it turns off the power generator after pumping for a minute or so
Short circuit
Thanks for the information
My pleasure
What you are doing is important. I called the two well service company’s that are close to my farm and still have not received a callback. Water well stoped pumping sometime last night. We watched your videos several times. We took notes and found an old Fluke 77 in the barn. Changed the battery and followed the instructions as close as I could with a different meter. You explained the process so well…. Get it Well. That I was able to check the well leads and the controller box capacitors and trip switch with confidence. I even downloaded the Manuel from your description so that would know the resistance readings for my particular 1.5hp pump. I guessed at the depth for the well and was able to find the numbers that gave me the confidence to conclude the pump was just fine it had to be somewhere else. Start-Up capacitor in the control box is where the numbers weren’t quite within the proscribed tolerance. Made some desperate calls to the local venders within an hour drive and secured a replacement box wit new capacitors. We won’t mention the speed but they closed at 5:30 and my wife hinted that dinner on the stove required her being able to shower tonight. That was all the incentive I needed to get the new box switched out and the pump running.
You look good in hunting season scruffiness.
In closing, I must say again. You are doing a service. It is not always about saving people money. I would have paid to have it done. In my case I still have received a phone call from the service company fixed it two years ago for my grandfather. He is not here anymore and it is ok. I need to start somewhere. He always told me that is he hadn’t learn to fix is own tractor in the early years of farming. He would have never made a dime at the job.
Cheers and Thank You,

Hello, I can't get over 20psi at the pressure tank and the pump keeps running. Can a well pump wear out and only be able to create 20psi ? I isolated the water flow to just the pressure tank not the rest of the house, I also checked the air pressure in the tank and it's holding. I'm actually happy that it's not the old galvanized pipes in this older home.
I have the same issue, how did you fix this?
@@adamhansen9261 I finally called a well pump service company, they said the pump was done. I watched the procedure and one of the 21' pipes had a whole and was dumping water back down the well. Our well had 6 pipes.
Don't know anything about the meter you have. So you lost me
When do they change oil
Hi!
Am using single phase submersible borehole pump ! But the switch(on &off) for the control switch keeps on burning to ashes! What could be the cause.
Have a 230 volt 3/4 HP , 13.8 gpm , what are my ohm values for this pump , Thanks
The only thing I understood is that the meter Is cheap....lol
What could be the reason for mine, when you switch it on the light n the switch will not come up, but when you remove the pump supply or remove the positive to capacitor the light comes on and the pump will not run. What could cause that sir
Where can I get the book
Thankyou help me more sir
I have and old fluke meter that was made in early 90s but works great
Very helpful. Thank you sir!!
Glad it was helpful!
Sir way 5wires
Thanks for your video, I have Franklin Control Box Model# 2823008110, 230V, 1.5 HP. I am not sure how to find the associated Motor Model Prefix in your reference, but I think it should be 224300. I measured resistance following your video, setting at 200 ohm, the main (yellow and black) read at 4.1, the standard (yellow and red) read at 10.1, and Red and Black read at 13.1. All insulation testing is good. Is my pump in good sharp? If it is, then I will replace a new control box has all the components to see if it can start to work. Thanks, David.
Great vid. My system failed suddenly. Control box checks out. I performed these windings resistance tests. Seems I have very low resistance on all conductors to ground indicating shirts to ground. But I’m also showing 20k ohms or more through the windings indicating opens in all windings. How would this make sense? Thanks.
Windings or coils are connected. In america for 240v acts differently than most of the world. Most the world only uses 1 hot leg for there 240v. The 2 hot legs in america are both 120v and 180 degrees out of phase to each other so one wire is negative at the same time the other is positive and they change polarity 60 times per second so the electrons travel back and forth as they constantly want to be on the positive leg.
Hello... How are you
Excellent videos. Diagnosed my problem exactly. Fortunately, my problem was only a loose connection not a bad pump.
Good to hear!
The motor is not taking water and the cable is very hot
My well has recently started acting up. The reset switch pops after about 3 minutes of run time. I have replaces the run capacitor, no help. Today I put a Fluke Amp clamp meter on the pump wires (1.5 hp motor) it was running along at 1 - 1.2 amps, the relay chattered and the amperage shot up to 6 amps and the reset popped. What could be causing this? We only use the well for watering the yard now but I'd like to get it working again.
Sounds like either a loose connection or the pump is going out.
@@RCworstwater Thanks I think I have determined that the pump is bad. I'll just have to wait until I have the funds to pull and replace it, we're 420 feet deep so I'm looking at about $3000.
My pump stops pumping after 10 minutes and if I should switch it off then turn it back on it will start pumping for another 10min. Wat can be done to solve this problem.
Help My pumptec keeps shutting down at 30 psi. It connected to a Flint & Walling 1 hp 10 gpm 230 volt submersible. Pumptec sensitively is at the complete minimum. I disconnected the pipe leading to the pressure tank and water flow seems weak. Any ideas are appreciated.
Thanks
How many lights does the Pumptec have? If it has 3 and the middle yellow light stays on ..... you are over pumping the well. If it only has 2 lights, green and red, I would replace the Pumptec before anything else. The 2 light units are the older model.
