Submersible pump

[Just Primer]

We have water rights where I live. I can flood my archer 1 or 2 times in the summer and some years even more depending whats available. This is my first time in this house and I am the last one at the end of the canal. My property seems to be much higher than the canal compared to the others in line. The previous owner had one 6'' pipe set real high at the top of the canal to flow into the yard. However I can water one time during the weekend and the idea is to flood the whole yard. He did set it up with a slight trench that runs around the border of the property first from that pipe. I was thinking of running more 6'' pipe, but now I am considering running one or two Sub pumps. Then I might just fill the canal half way instead of just a foot from the top that is close to flooding out the highway in front of my house.


Can I run a 1/2 hp or a 3/4 hp pump off a small generator that runs up to 800 to 900 watts like the tailgator from Harbor freight. I already own one of the old models of this generator from them under a different name and it runs great. I was able to power a small force fan heater of around the same wattage. It was labeled as 800 on low.

1 hp equals ~750watts. Should have enough power and work ok as long as the generator will power an induction motor. Sometimes the electrical wave form is square instead of a true sine wave. But this happens mostly with inverters, not generators.

It wont start a 1 hp motor, its too much for one of those little gensets.

It sounds to me like you need a 'trash pump' that is powered by an internal combustion engine. Trash pumps move a lot of water without much head pressure, and that is what your doing. I wouldn't stick a generator and motor between your engine and pump.

With those height differences can you get a siphon going?

My nieghbor next door said that i could possibly get a siphon going. I just want to water as quickly as possible. There are so many other houses on the flat rate that it seems like it might be a train wreck to me. He thinks I could use a heavy gauge cord to plug in a sub pump to my house which is at least 25 feet away, but I am skeptical. I have heard this before and it always ends up with me picking up the extension cord with my hands and it being fire hot at the plug or all the way down the line and then breakers tripping over and over. I no all the pump manufactures say no extensions.

Ayuh,.... Ya need to run a 10ga. or 12ga. extension cord, not a 16ga. or 18ga. cord,....

You can fill the siphon hose from the low end with a pump.
When you turn off the pump the water will reverse in the hose.

750 watts at 120v is only 6.25 amps. That is nothing. You shouldn't have much of a problem with a 16ga cord, but bigger is better. My brother and I will run easily 30 amps on 100' of 10 ga cord for our welders. 20 amps on 12ga 120v was fine for my old 120v miller 135 and I have run my small airless, air movers, saws, compressors, etc. on the same.

Check your voltage at the source and also check the size of the wiring to the receptacle you plug into. If there is already 100 feet of 14ga romex to the receptacle oh your house and you add more small extension cord or have low voltage, then it won't be good. Lower voltage = higher amperage = more heat in the cord.

If you can run shore power, that would be more convenient and you might just have to flip a switch when you water. Personally, I would prefer that to messing with a generator or gas powered pump every week.

Most HF stuff is junk. Sometimes you get lucky, but this could be part of your problem if you used an HF pump in the past. Maybe you could borrow or rent a pump to try out your plan. If it works, try a HF pump and if that fails, it probably means you need something built better.
