I doubt the Carolina rainfall is as regular as what the pacific northwest receives. He would have to build a tank farm to store enough to do without any well water.

Ive worked with 4gpm on a well before. I think we ended up planning on 8 to 10 gpm zones.

The well driller went like 650' and dropped the pump near the bottom for the extra capacity. This i remember gave us a certain amount of gallons capacity to work with. We set the controller up on delay function between zones to recover the well.

Make sure you install a VU-FLow sand filter after the isolation valve on the system. Dont install the filter between the pump switch and the hell head, you'll blow the filter out, as if it fills up with sand the switch will not get the pressure reading to shut off. (seen knuckle heads do this often). Install a T in that line with a isolation valve and go from there for the filter then to the system.

Your well driller needs to give you an idea of how much gallonage reserve your have, then you can start planning your system.

It will be some trial and error after that on the run times/timing/delay between zones.


BTW, we get rains very regularly here, weekly at least.

By the way, what is the water level in the well?

If you know that you can figure your storage in the casing, 1-1/2 gallons per foot.

If it starts high, then you can pump from that stored water, with pressure dropping as the water level goes down. If not so high, then a pump-from-the-cistern arrangement would make more sense, giving you predictable system performance, and eliminating sharing issues with the house, plus simplifying backflow plumbing.

Good question... I will check to see if that info is on the well, if not I will contact the well driller to find out.
