Pressure tank location question

[triwayne]

I would like to pump water from my pond to run my sprinkler system. Total rise from lake to sprinkler main "in" is 31'. Total distance from pond to sprinkler input is ~120'. I know nothing about the sprinkler system (zones, heads, etc..) Former owners left no documents/specs and also removed flow meter when they left.

My cheapest option is to purchase combo pump/pressure tank and install it at the shoreline then run 1" pipe to sprinkler main in. However, I'm not sure if this would work.

Here are the specs for the pump
specs: http://www.northerntool.com/shop/tools/product_200664799_200664799?cm_mmc=Google-pla&utm_source=Google_PLA&utm_medium=Water%20Pumps%20%3E%20Shallow%20Well%20Pumps&utm_campaign=Powerhorse&utm_content=50299&gclid=CjwKEAjw6e_IBRDvorfv2Ku79jMSJAAuiv9YaVKUgZF9Q65EVs0qMtSXE6QajfKD9P2RkzcJv3yGhRoCkBTw_wcB

My other thought was to put a submersible well pump in the pond and pump water to a pressure tank near the main sprinkler input. This should be enough to power the system but is also more $$.

Thanks in advance for advice/tips/hints!

A pressure tank with a pump will not work very well for irrigation. It will cycle to much and if the pump is too small you will lose pressure at the sprinklers as pressure is lost trying to fill the pressure tank at the same time.

Get a 2hp 220 volt irrigation pump will work best if you have the power to the pond. You must look at the pump specifications and see what the gallon rate per minute and at your rise. The higher you pump (suction side) you lose a lot of flow. This URL has a 1 1/2 hp pump and look at the flow rate chart.http://www.flotecpump.com/ResidentialProduct_fl_lg_sp_FP5172.aspx

Here is a url and you can read over manuals for irrigation pumps. It does have some things to avoid and do. There is more to it than most think. It not hard, just a lot to know and it would take pages of text to explain it all.

The simplest way is connect all zones and remove all valves. Run the 2 HP pump(2" outlet) with a simple on/off timer and irrigate the entire property at once providing you have proper water flow from the pump to handle the number of sprinkler heads. All you will need is a check valve or two. My neighbor did this and it worked really well. Dropping a submersible pump in the pond will work but you may suck up mud and debris that will mess up the works.

Thanks for the advice! I think I will go this route.
