I'm getting ready to have a well dug on my property. 3.25 acres. Along with household use, I plan to drip irrigate a bunch of trees. Well will probably be 220 ft deep.
The first bid I got from my well guy, he suggested a 1.5HP motor and a 20GPM pump and a PC266 tank with 1.25 PVC SCH 80.
I then told him I wanted to irrigate trees and grass around the house. He then bid a 2HP 20GPM pump, PC366 tank with 1.25 SCH 80. The price went up a bit. Fast forward a few months.
I talked with him yesterday (the receptionist girl, actually) and asked her to confirm that the above was the proper motor / pump, and she recommended (after talking with someone in the background) a 2HP, 20GPM pump, PC66 tank (much smaller) and a sub drive 100 constant PSI controller, with 1.25 SCH 80 pipe. The price went up again.
Any well experts out there? I was just reading (on the franklin web site) about constant pressure controllers. Seems the controller merely controls the (sometimes existing, in a retrofit application) motor and makes it variable speed in order to keep the pressure constant. Do I understand it correctly?
Is this what I need? I guess my concern initially was volume of water, not really pressure. However, I understand I need pressure to get the water out of the sprinkler heads.
When I call an irrigation guy the day after I close on my house, will he be telling me "so sorry - not big enough"? Lot is roughly 250 wide and 580 feet deep. Well will be about 200 from the front, and the longest irrigation run might be 300'.
Thanks, Todd
