For an acre-and-a-half, 50 gpm is overkill, even on sandy soil. 20 gpm would do just fine, which keeps you with standard 1-inch zone valves. This also changes the pump situation. You can use a 1 HP jet pump, which gains more pressure in exchange for delivering less flow.
As for the system drawing, it lacks a scale, so no one on the internet can know exactly what you are looking at. You need to add a line with inch markings.
Attached is my rought scale drawing. I laid out drip irrigation for my trees and shrubs this weeked with the wife. We ended up going with emitters and a main line. Its all above ground but we will be buring it later. We went with a 1" poly pipe. We had to go that large because we only have 15 lbs static pressure atm and are waiting to put in the pump.
Its all running off the turnout nicely, but will balance out better when we can finally add pressure to it. I may do it on one or two zones, but right now its all running at the 15 psi.
50 gpm is over kill I know, but its nice to have. What would you suggest, We have 10 or so sprinker zones,
Is there a good pump that would run two seperte zones at once, I have found quite a few but its almost impossible to find pump curves on them. I would like to keep it to about 500.00 for the pump but then again I maybe dreaming?
I do have static pressure of 15 psi, so does that mean I would only need to find a pump to boost it 35 - 40 PSI?
What is the difference between a booster pump, a jet pump, or the other types of pumps on the market.
I have not run my eletrical yet, so I would need to run it about 150 feet to my water shed from the house so I need to be thinking of that, if I need 120 or 240.
Is there a cost difference to run a 120 vs. a 240 pump, I know 240 you can run it on a smaller breaker, does that mean wire as well? But then I would need to bury two lines to get my 240 volt?
If I were to water all zones one at a time how long would that take, there are 10 sprinkler zones.
This is the controller I would like to use
THIS ONE. If I am reading it correctly I can us this for up to 12 zones and its a controller, I don't need anything else besides my PC. Any feed back on it?
