Hey, I just saw a response to a question that is EXACTLY what I want to do but not sure how to size the pump etc. This was the response to the guys question of "Jet pump without pressure tank"..... :
Whoa You have a 1550 gal. holding tank. (This is a holding tank and not a pressure tank, correct?) and this tank supplies your cabin through gravity feed? If that's the case then no pressure/bladder tank or pump control box should ever be installed. The pump shut of should be a float valve in the holding tank. It works like this. The jet pump operates until the holding tank if filled and then the float switch shuts the pump down. As you draw water into your cabin outta the tank the level falls and the float switch kicks the pump in again and the process starts all over again.
I have an old open well on this property I bought... I just want to put a submersible pump or Jet pump (?) in it and pump to a holding tank with level switches .... the tank will gravity feed to my livestock tanks... and maybe eventually I will filter it and use it in my house (which is another question). But for now can someone hold my hand on how to get this going just to supply water to my livestock. I want to power the pump with solar.
THANK YOU SOOOOOOOO MUCH! I am so happy I found this site!
I can't help with the solar power But I can help a little with your pump. The size of your pump will depend on how deep the water table in this open well you have? I wrote the above answer on the gravity feed cabin supply. Yours is no different. This will be a simple hook up. No bladder tank, no control box, and no pressure tank to hassle with.
Let's find out how much lift the pump will have to provide, (How much higher will the holding tank set in relation to the well head?) Let me have all the details and we'll get busy. Regards, tom
I can actually set it as high as needed since I am not committed to anything yet. And I am fortunate in the way my land slopes.... it is a problem in all areas except when I think of doing my water supply to the rest of the land. My well is at the top of my land... EVERYTHING else is down hill from it!
I just now took a tape measure out and moved the piece of tin covering to the open well and measured from water line to land and it was about 7 feet.
I am not a plumber, but have done alot of research on Solar well pumps and systems. The best setup I can find is located at this site, and they can answer alot of your questions there on line. Grundfos USA
The well head is elevated and the water table's only 7' down from ground level?
Excellent! Living in a metro area I haven't a lot of pump experience but it seems to me that you could put a well point with a foot valve down 15 or 20 feet and with a 1/2 horse centrifugal pump supply your holding tank, gravity will get the water down to the watering trough. How do you plan on metering the water from the holding tank into the watering trough or will you have a valve at the terminal end?
Regards, Tom
If the watering trough is below the well water level, put a hose in the well and down the hill. Fill it with water and then open and let a syphoning action draw the water out of the well. No power needed
SB, you are right about that, but if the cycle is thirty or forty gallons at a time into the trough (pure guesswork), that would be better than what happens with many pressure tanks which is 5 or 10 gallons. But you do raise a good point.
HK, I just can't imagine water 7 feet down at the top of a hill. Doesn't that sound strange to you guys?
Sorry.... but a long day here on the farm and I didn't get to check this!! Yes... I walk up the slope to the top of my yard and look down into my open well... and measured 7 feet to the top of the water line! Now I really need to find a rope and weight to measure exactly how deep this thing goes.
And I need to water 3 areas with this water.... my chicken coop, my pigs, and my horses! But that is no problem with a simple float valve at each trough. I currently have one now at my horses.... it is attached to the trough and I just attach a regular garden hose and it valves off when the level is full in the trough... no power needed either!
I just wasn't sure how to pump it to a holding tank to let gravity do all the work!! Thank you guys sooooooo much... this is awesome! I think I can figure out how to power my pump with solar... just need to know what type pump etc.
Thanks again and I look forward to more brainstorming on this!!
