Pumps, the concept of head

[Kaduda]

Ok,. Now I understand head thanks to you guys.

So here is my thinking. I could go with a shallow well pump (eg: http://www.homedepot.com/webapp/wcs/...ocStoreNum=589) as an example. Most that I see here in the States are rated for 7m depth.

thoughts?

Pumps like that usually have a pressure switch...In the unit above, it is pre-wired with 30 - 50 psi pressure setting...Meaning the pump will turn on when water pressure drops below 30 PSI and will turn off when it reaches 50 PSI in which case you would need a pressure tank...Not sure if you could use an IBC as a pressure tank...But the plumbing aspect would be easy...Just T in the pressure tank...

A backflow preventer valve like this pic http://www.relianceworldwide.com.au/ryemetal.html have to be fited on the suction side or you will have to prime the pump again after each stop.
Also you would probably need a small sieve to prevent the valve from cloging.
The pump you linked is not meant to run constantly but be equipet with presuretank like Kakuda say.
I had one runing for aprox 14 months before it broke down.

It is a better solution to push rather than suc the water, initial invest and constant runing cost, also there is "particles" in the sump water, the pump should be designed for that wich vellpump arn't.

Try to make a layout (Configuration) your idea of the set up you have in mind, easyer for us to try help to figure a solution with you.

Well then it's back to square one sort off, he want's to locate the pump by the electric wires, wich put the pump above the water inlet of the pump.

Since we have gotten this far.... Here is a link that shows the layout of the property with contour lines --

https://docs.google.com/open?id=0B-n...UwZmNlMjQ5ODA3

Property is approx. 210' width x 430' depth

Legend
-----------------------------------------
Contour lines:
- white = 2' elevation change
- orange = 10' elevation change

Yellow square = IBCs, @ ground elevation
Green square = growbed(s)
Red square = sump, partially buried
Blue/white circle = pump
Yellow line = pipe, outflow to growbeds
Blue line = pipe, suction side of pump
Green line = pipe, discharge side of pump

I have not included any filtration equipment to keep the flows simple.

I appreciate the input.

Hi again JMc
I would build a more integrated (estetical) AP garden iff it's your permanent home.
This http://www.backyardaquaponics.com/fo...hp?f=18&t=5504 is amongst my favorits, show it to your wife and I bet she gets hooked on AP as well, having livestock makes a big impact on family life, so bringing in the family on the project, makes a big difference is my experience.

cheers

Ande,

I agree on the value of making it visually pleasing. Long term there is a spot between the workshop and the house I intend to turn into a pond to hold more fish. What is not clear in the photo is the number of trees on the property as the aerial was taken in winter. Most of the property is totally covered in oaks. That dictated where the placement of the growbeds would be to a great extent.
