Voltage was the same under no load, which makes sense. When you draw a current, the voltage will be dropped across the wire since it is acting as a low value resistor. Measure the voltage on the input of the pump and it will probably be somewhere around 7-10 volts, dropping somewhere around 3-5 volts across the extension cord.
Thanks for taking the time to explain you experience with this pump on you project You definitely make me take the decision to buy one for my atv trailer tank to water my plants. Keep it up and thanks. And yes is beautiful to watch that you project worked for you.
When measuring the voltage at the distant end of the extension cord you must measure it under the full load of the pump. Otherwise there is NO current flow and your voltage will indeed be the same as the source.
Begging your pardon, but that's not correct. The meter initiates current flow by completing the circuit, and in this direct current application will return a value of 12.19 volts regardless of measurement location or whether the pump is operating. The variable that changes under load is amperage.
@@fungoorstitch The impendence of the meter is more than of the pump, MUCH more. That pump pulls 18A and that extension cord is probably 16 or 18 gauge copper. I would expect an large voltage drop down the cord (200' both ways). Be careful correcting people. Scotty T may still be correct but you are wrong. Now its you with egg on your face sir.
The voltage drop occurs when current is flowing. Plug in the load and measure the voltage drop from the minus terminal on the battery to the minus lead on the pump. Then measure the voltage drop across the positive terminal of the battery to the positive lead on the pump. The pump must be running. To test for an open circuit voltage just measure across the gap between a blown fuse. If the fuse is blown the voltage will be the same as the battery. When you measured the voltage on the extension cord it is the same as an open circuit with no pump load. So, the voltage is the same as the battery. To measure the actual amount of amps the pump uses disconnect one of either lead from the battery. Switch the meter to the amps setting. Then connect the red test lead to the battery terminal and the black lead to the wire from the pump you took off from the battery. After you are finished with your measurement please install a fuse rated at twice the current draw of the pump.
Thanks for actually showing the details of your Seaflow pump. So many other vids only give the brand and no model info for viewers to then research according to their own situation.
Great project. You can measure current by hooking your battery to the pump as you normally would but leave the positive clip off. Turn your multiple meter to read DC current, connect the negative (Black) probe to the positive clip that you left off the battery and connect the positive (Red) probe to the battery terminal. This is a series connection to measure DC current through the positive side of the circuit.
Woow very nice just bought one almost the same i like the innovation of sprinkler am looking fowrd to use one for pumping water for under ground to the tank up
Electrons work just like water, think of the inlet pipe, 1/2" works for 10' but if you want to go longer you need a bigger diameter pipe. If you want the wire more than 5' long the wire has to be bigger in diameter - bigger wire = lower number Wire gauge. I like your setup!
When you have the long cord connected and measure the voltage at the battery then at the end of the cord the meter itself is the only "load". The meter internal resistance is most likely over 1 mega ohm (1,000,000) ohms. It draws extremely low current (amps). Try the setup again but have the pump connected and running, then measure the voltage at the battery and then also where the extension cord connects to the pump. I assure you you will have far less than 12 volts at the pump end when the "load" of the pump is running. The rest of the voltage drop occurs because of the resistance of the wire. You could improve the performance using an extension cord but the wire needs to be much larger (lower gauge number). A larger diameter wire has less resistance. Again, the meter alone draws such a small current the gauge of the wire has less effect. I just looked at seaflo website, that pump draws 17 amps. Even for a short connection you should use a minimum of 12 gauge wire to minimize voltage drop.
That little pump does a good job. I hook up a Powerfist (Princess Auto) 1" pump to my rain tote and water a similar sized garden in about 10 minutes. Its a little noisy but its kinda fun.
What you need to do is connect the pump through the extension cord then read your voltage AT THE PUMP WHILE IT IS RUNNING. This will tell you how much voltage you are losing to the resistance in the extension. It is good that you brought the battery to the pump. If you insisted on running 100 of wire to the pump at 12 volts, you would have been running arc welding cable. 200 feet on 00 arc cable would cost you more than running 100 feet of 10 gauge romex and a new 120 volt pump.
the reason you get less power from the battery when you have a long cable is because the longer the cable is, the more resistance the wire will produce, you might notice with high power draw it'll also get warm or hot depending on how thin the cable is, it happens with mains as well, but because it's already such a high voltage (and slightly different power type) you normally don't notice it. the way you can make the cable longer is by using a relay system, they're a bit confusing to wire, but it'll definitely work... you can also get a super thick cable, but that's way more expensive and not worth the setup you've got.
you have to connect the big consumer to power cord in order to see the voltage drop. The voltage drop is caused by the current, the length of the cord and the section of the cord. Measuring the voltage drop without the consumer results in almost zero drop voltage.
That type of pump is self priming. You only need a screen filter on the suction line. If the foot valve has a spring in it the pump might work better if you take out the valve and spring.
Of course. One hundred feet of cord is going to have resistance that will drop voltage, but you won't see that drop unless you load it with the pump (and draw current). Measure at the end of the cord with the pump connected to it and you will definately see the voltage loss.
You can use a 100 foot cord IF that cord goes to a relay at the short 12 volt wire. Then your switch can be at the garden, but the battery still will be at the pump.
Try using 1” hose for in and out of the pump. Flow will be better - water resistance from hose will be less too - your will get more hours on your battery too - pump may be even running hot - you are making the pump work real hard.
Thanks for this video teaching on irrigation system for farm. What do you advice me to use to construct a system like this,that will be efficient like yours for a farm land up to 50ft by 100ft in 200 times? What is the type of sprinkler you are using? I would preferred you help me with list of materials to use in your reply. Lastly, can one connect solar panel to be charging the battery? If yes can you be of help to let me know how to go about it, my farm is suffering for water.
I'm sure it has been mentioned before, but try a solar panel coupled with a MPPT charge controller with a timer on the pump. Totally automatic, ongoing operation. Also, the more you deplete the battery, the faster it will die. Never past 50%, and only with a deep cycle battery. A starting battery is a waste of money for something like this as it will not last.
Thanks for the useful information, I was surprised to see how much garden that could cover! I wouldn't have guessed that an RV diaphragm pump could run for more than a few minutes at a time - since that is how often it runs in my camping trailer. I have a similar application and would like to know how well the pump has held up the past 2 years.
a small solar setup wouldn't really be a "waste", all you need is a battery (which you already have), and ONE small charge controller, and ONE panel... Then you'd never have to lug the battery around to manually charge it! You could take it a step further and add a "timer" to automatically turn the pump on/off at certain times. Then you'd never have to manually charge or turn your setup on/off. Your garden would always be *automatically* watered, same time, every day!
How many nozzles you fixed and at what is the length and type of nozzle. spraying water distance etc.. Please reply as you said there is no video like this in TH-cam .thanks for sharing your experience and knowledge.
Thanks for that. I just bought a seaflo pump so it was nice to see you were happy with it. Why don’t you buy a cheap solar panel set up to charge your battery?
Nice setup. Looks like there's enough room in the box for the battery, so you could have even shorter wires. Plus it'll keep it sheltered and hidden. P.S. I could tell from your accent that you're a fellow Canadian. French Canadian?
look for a used solar panel, you can a 250watt for $40 to $70 in facebook market or craigslist. with that many watts you can run the pump directly from the panel. thanks for the video.
Hi. Very cool watering system. I am thinking of buying that exact same pump for a garden project. Do you know whether it will shut off if the water source runs dry?? I am going to be using a tank. Thanks.
@@frenchriversprings Thanks for the reply. So you bought the battery clamps separately. What size or gauge... is 10 gauge okay 10 feet length out less? I'd like to connect to my truck battery or the batteries for my trailer. Is there a way to connect to a car lighter outlet. Thanks:)
I don’t remember what size clamp I bought. I would not recommend lighter outlet. For your cable, do not use longer than 4’ long. If you go longer the performance will be reduced. You can’t use a cable and clamp that is too big. Better oversized than undersized especially when you deal with 12volts.
@@ظلالالجريمة-ث4ز thanks for that, just browsing now and the best I can see is a 10A 220 - 12v cigarette charger.. so thinking I'll just then solder a cigarette lighter onto the pumps wires and hey presto 🤔
You don’t understand voltage drop! Run 12v through your extension cord 100ft with the pump connected and running. Measure the voltage at the battery and then measure it at the pump. I assure you, you will get a big voltage drop and that’s why your pump doesn’t run off a 100ft extension cord. You are measuring voltage drop on the 100ft cord at no load which of course you’ll see the same voltage as the battery because there isn’t any load connected! You need to increase the wire size to decrease the voltage drop! The pump draws around 15/17 amps, the battery will not last long, you should add a solar panel and charge controller around 200watts of solar will work to make sure your battery will keep a sufficient charge when the pump is in use.
Do you remember the length and width of that garden and what about the sprinkler. I could use a couple of those for by back yard. I would say its the same in width but about 2 and 1/2 time in length. Thank you
Great review on this pump I just purchased one with the wall outlet on the discharge end of the pump you have a brass fitting to fit a water hose could you send me link to purchase one thank you
how much pressure do you get in psi from such a pump? Is it comparable to the pressure you get on a external house bibb? I'm trying to use such a water pump to pump up a giant balloon. Wondering if it will work.
Rain barrel is small and for his size garden would use up the whole barrel in only 11 minutes because a barrel is typically 55 gallons and the pump consumes 5/minute. So you need a 275 galon tote which has 5 barrels worth. otherwise you need to fill your barrel every time.
lol, the voltage is the same because you have no amperage draw. Hook up your pump to battery and test, then hook up your pump at the end of cord and test voltage at pump and voltage will in fact be down low! amperage and voltage work together lol

Measure the voltage on the input of the pump and it will probably be somewhere around 7-10 volts, dropping somewhere around 3-5 volts across the extension cord.

@ 8:40 you test the voltage. You have to put your load on the extension cord before you will notice a voltage drop. Test it with the pump running.
