Thanks for simply pointing to the ejector and foot valve lying on the table instead of lifting them up and showing us what they look like, haha. Great video though.
How to clean ventury nozzle
OUCH! Still same error as 5 years ago. . .
The hose squirts farther because the pressure is HIGHER inside the hose! Try measuring it and you'll see.
The finger blocks part of the hose and therefore increases the pressure in the hose.
,
What you either gloss over, or appear to miss is that the pressure is lower AT the opening. The pressure here is atmospheric pressure which is lower than the hose internal pressure and this pressure difference accelerates the mass of water to the higher speed into the air.
..
If the hose pressure STAYED THE same:
It would squirt the same because the area of the opening is smaller and so is the amount of water in the opening. The force decreases in proportion to the area. If the pressure was the same, this reduced force matches the reduced area and water mass. The decreased force matches the decreased mass... thus, the same distance squirt.
...
Therefore, the pressure must increase if it squirts farther.
As I say, measure the hose pressure when you put your finger over it.
You'll see that it increases with the finger.
....
Jet ejector pumps work due to entrainment which is caused by viscosity. It is incorrect to say it is lower pressure due to speed rather than entrainment.
The lower pressure is due to the entrainment dragging water away from the source. The jet itself does not have lower pressure due to the flow speed.
Hello. What would be the best pump to draw water out of a 6ft sewage drain?
Great video! I have a question? Can a handpump somehow be added to your water well (jet kind) incase of emergencies and the electricity goes out? I seem to keep running into videos for submersible wells only. Thanks so much!
So on the deep water system, does water flowing through the drive pipe draw water through the foot valve by the venturi principal? How is water prevented from flowing out of the foot valve?
Nice Video, how far from the bottom of the well should a submersible pump be? thanks?
10' off the bottom is where we set them
Great video, unfortunate company name.
great explanation should have a little more cross reference thanks
Thanks for the comment! What part did you want more info on?
Thank you for the video I can't find a solution for fluctuating water out for 12m depth and 2.5 hp pump sucking section 1"1/4 and 1"
it seem that pump doesn't have enough water
thanks
The deep well illustration beginning around 2:46 has the larger pipe pipe labeled as the return pipe, but in the audio narrative at about 3:13, the return pipe is said to be a smaller diameter. Which is correct?
He is using the word "return" in two totally different ways! No wonder you are commenting on it.
The big line, 1.25 inch, is the suction line, water is brought up.
The small line, 1 inch, sends water down to the jet. Water travels down into the well.
What he was saying is the small line "returns" water down into the well, and the big line "returns" water up to the pump. HaHa.
Great videos Chris!!
We have a (shallow well) jet pump starts running when we are using water in our house. It runs well but suddenly starts “jacking”. I searched cavitation and it’s not the same sound. It would be similar to the power surging. Like the pump sort of starts “chugging”. It’s on the floor in our utility room, connected via a braided wire covered “hose” to a valve to a “drain valve” (looks like the taps outside of your house for a garden hose) and into the base of our water holding tank.
Any insight?
It sounds like your pressure switch is too far away from your pressure tank. When the pump shuts off there's a "wave" action that the pressure tank helps to dissipate. If you're more than a few feet away from the pressure tank then it will not be dissipated enough and your pressure switch will rapid cycle.
Brilliant
Is a Multi-Stage Centrifugal Water Pump better than a jet pump. I'm pumping water from a main line with little to no pressure.
I want an option that will full my containers fast.
hello!! i want to convert a jet pump to an ordinary pump. which one hole do i have to seal for better efficiency, delivery or return ??
Give us a call: 855.329.4519
The pressure pipe hole
Thank you for the video!
My 3/4 Barracuda shallow well jet pump is making a deafening whining noise. What could the issue be?? It’s only 2 years old. I’ve been told bearings...motor...?? Help!
wait a minuten, if regular pumps can only suck max to 9-10 meters of water, does that mean that injector pump with injector mounted right at the front of the injector pump can suck up to 20 meters has the manufacturer clames, or do i have to send the injector down the water at 18-17 meters ?
Does "distance" refer to depth from, length from the pump or both? Does the height of the water surface come into play? For example I have a Gould HSJ20N shallow water jet pump. The intake hose is 30' long which extends straight out into a lake where the intake sits about 8' under water and overall about 10', if measured vertically, below the pump. The lake level recently was dropped about 7 ' for a repair. So now the pump is only about 1' under water, but same distance from the pump. The pump is now overheating, hitting around 258 deg F before it eventually kicks off. Could just the water level drop somehow cause this issue or should I be looking elsewhere like an electrical issue? It sounds normal to me when running and it is getting plenty of water at the intake.
Thank you, sir. Great video!
This is one of the best how to videos on youtube.
@@salehal-kandary6573wow what constructive feedback. Please make a better video about this topic. Thanks.
I think the nozzle came loose on my jet pump. How do I know how much torque to use when installing the nozzle?
Hello, is there any solution or modification to transform normal water pump to water jet pump?
Awesome 👍🏿 much love.
Thank you! Cheers!
Would this work in a camper to bring water from my well to the camper?
Thanks po sir.
Between 3:43 and 3:53 we hear that the venturi & nozzle must be carefully matched to the pump and system needs; however, there ought to be some overt mention made when replacing an old convertible 2-pipe jet pump with a new pump that the old deep well jet ejector may be used, or should never be used with the new pump.
I’ve been calling it an ‘Injector’ for 35 years 😂. Maybe that’s common and the guys at the pump shops I goto also call it that?
Great job explaining this, thanks
It is a jet pump and works due to entrainment, not Bernoulli. The pressure out of a this and the garden hose nozzle is not lower because of the speed. It is lower because it opens into a lower pressure atmosphere. As you restrict the nozzle more and more, the pressure INSIDE the hose increases. That is why it shoots farther. It the hose pressure stayed the same, it would shoot just as far Do the math on area, pressure and volume.
Late comer to your vids but thanks a bunch for the education. Most jet pump vids I've seen talk about single stage pumps with deep well limitations of 75-90ft of lift. But I recently came across a video on Goulds SJ series multistage jet pumps capable of pumping water from as deep as 200ft. They're considerably more expensive but I'm interested in your thoughts on those.
I recently had a well drilled that is 250ft deep with 30gal/minute flow from 240ft, in a 6" casing. Static head is 50ft and I don't know what that level drew down to during the flow test. I'd prefer to use a jet pump so the the SJs caught my interest.
For that depth I would recommend a submersible. What's the reason for wanting an above ground pump?

How do I find 150 foot jet pump well I need to no
I am using a 1.0 HP submersible pump to lift water from a 55m well. The pump is set at 49m and using a 1-1/4 pipe. The pump doesn't seem very strong and I was told to not run it for more than 30 minutes at a time. Once I connect a pressure tank (and switch) the well water will go through a filter and treatment system before filling a 1500L holding tank. A whole house pressure pump will supply water from the holding tank to the house. How (where) can I add a second pump to use the well water (continuous pressure) for landscaping and fill a large fish pond? I was told to replace the submersible pump with a deep water jet pump? Thoughts?
There are a lot of questions we need you to answer before we can offer any advice. Please give us a call: 855.329.4519
What is that black hose coneected on the pump called??
Thanks for the Question! That small black tube is sometimes called a pressure tube. Water travels through that tube and into the diaphragm of the pressure switch, allowing the switch to monitor the pressure in the system.
R.C. Worst & Co., Inc. Thanks for replying! Now if this tube were to tear by what means would it be replaced??
You should be able to find them at your local hardware store or whoever you bought the pump from. Installation procedure varies from pump to pump, you're best bet is to call the pump manufacturer.
Can u plug bottom hole on pump and use as shallow pump
It depends on the pump. Sometimes you will need a shallow well ejector added to the face of the pump. Give us a call and we can help you determine what is needed: 855.329.4519
Hi , Ive bought a property that has a injector down by the lake. The pump up at the house only has one inlet . There are two pipes returning from the lake , one bigger than the other.
Im confused to witch one connects to the suction on pump? Does any one know ?
Both need to connect because you are likely pulling from greater than 25' elevation. The original pump that was there needs to be replaced with the same model.
I jus order a jet from amazon shot hop I didn’t mess up it was 67.00
Which is better in term of power efficiency . Jet pump or submersible pump
Submersible. They don't have to waste any energy on suction
Great video... I have a problem with a new RJC-100 pump trying to pump out water from well, we prime pump and try to fill PVC pipe and run pump, but the pump runs as we're filling the pipe and then the pump runs but it's not pulling water. Well drop is about 24ft but the horizontal length is about 600ft. Any thoughts?
I have found it impossible to prime our well pumps while the pump is running. Suggest you disconnect power ..good luck..
I have a jet pump w a little filter like thing connected to pressure tank w a thin line that runs to the front side of jet pump. What is that thing?
Can you email us a photo? Customer.Service@rcworst.com
Hi. can you help me ? what is the discharge pressure of jet pump?
What's the model # of the jet pump you're asking about?
need to find a jet pump for a 2 inch case ,..anyone!
We have 'em, give us a call: 855.329.4519
This was very informative. Thank you.
Glad it was helpful!
Does your company supply and ship parts for Goulds Jet pumps? I have a Frankenstein J5, and may require a nozzle/venturi change. My 1 1/4 shallow well system is new, ( brand new Simmons 1724-1 point, with about 3 hrs of run time in the ground) at a depth of 27', with a water table at 19', (or 7-8' of water in the pipe), and nothing but sand. My J5 (at ground level) will shoot water out of a 5 gal. bucket, about 15', and will M/T it in less than 10 seconds. Yet when I hook up the system, it only yields about 2 Gal a min. wide open, out of the ground. Was wondering if an improperly sized jet assy. would cause this? Thanks for your video series. Very informative.
I can't find your video on nozzle sizing.:(

I am finding that many sellers of these pumps call all of them jet pumps. Many are just centrifugal pumps for irrigation and shallow wells. I am going to attempt to use a shallow well pump from Harbor Freight as a pressure booster for a house trailer. Pressure is about 35psi and drops to around 20 when a valve is opened. I hope this will increase water pressure enough so I don't have to wait 30 mins for the tub to fill up. I think the proper name for these jet pumps should be venturi pumps.
We want to pull irrigation water from our pond which is 600 ft away.. There is no electricity at the pond so we will need to to use the electricity near the house . The pond is 600 ft away and the house is 20 ft higher than the pond..(so it is very gently slant) We borrowed our deep well convertible pump and used it as a shallow pump but could only get the shallow well pump to pump at a 80ft horizontal distance. Could we pull water over the 600 ft is we used our convertible pump as a deep well pump and had it by the house and ran two pipes to the pond? Would the deep well pump pull 600 ft horiontally?
Currently we can use a gasoline pump which pushes the water up the 600 feet and it is great. but we cant put it on a timer to water our garden and orchards twice a day (that a lot of water) Is there any other pump that we could buy to do this job? Any and ideas and suggestions appreciated. Thanks, Jenny
I forgot to say that we could get the shallow pump to pull the water the 600 feet horizontallty but only for a minute and then it seemed to lose its prime. Our pump is FE Myers convertible but we are willing to buy another one. thanks

Thank you!. I will have my husband call you today.
Nicely Explained :)
Thanks 🙂
I have the Goulds JRS7 jet pump. Over this past winter we had a period of prolonged freezing weather. I took much care to drain the pump and leave it unplugged for the past couple of months. Now that spring is here, the pump starts up but there's no water coming out. What's the secret to bringing it back to life??
Brenda: It sounds like you may have trouble with priming the pump. Check out our video on testing and priming a jet pump: ua-cam.com/video/Ff0ndfSFFJ0/v-deo.html. Call us if you have are still having problems.
If it froze with ANY amount of water in it, it may need to be reincarnated as a toaster. Now I'm rethinking my plan of using one. There's no easy way to prevent freeze damage.
Thank you.
Is it possible to use it as car washer?
It is possible, a small pressure washer might be cheaper and more effective though.
Can I connect this pump to live supply of water from administration?
Yes, jet pumps can be used to boost the pressure supplied by your city. There are local codes that have to be followed when doing so, usually a double-check valve must be installed to prevent contamination.
