After years of living with an old 1.25gpm well I will be having a new well drilled in a few weeks.
I want to have things like Poly Pipe, Fittings, CSV, Pitless on hand before the trenches are dug and a rough idea of submersible pump size, which will be fine tuned once I know actual depth, gpm, static level and such.
A) New wells in the area range in depth of 100"-130' and GPM in the 20's with an exception for my neighbor that has 110 GPM and 116' deep.
Static level varies from 45'-65'.
B) Ground is fairly level with shower head 10'-11' above area that well will be drilled.
C) Distance from well to tank/filter house is 90' and from tank/filter house to home 105' and from tank/filter house to last of 3 hydrants 300'. Only 1 hydrant will be used at a time, but house will always be used.
D) Well casing will be 6" steel.
E) Goal is at least 20 GPM (if well can produce this amount)
F) 40/60 psi switch
G) Shop that will supply electricity has unused 240v, double pole 60 amp breaker.
Added notes: old Sears and Roebuck diaphragm tank from the 70's died late August and was replaced with new Well-X-Trol, WX-302, 86 gallon tank last month.
Old shallow well has iron & PH issues and filters to reduce these problems, but neighbors with 100' and deeper wells have none of these issues and have no filters.
Questions.
1) Using a worst case scenario of 130' well and 65' static water level, will 1 1/4" Black Poly pipe be large enough to allow 20+ GPM?
2) Will 160 psi Poly Pipe be strong enough or should I jump to 200 psi? (If 160 psi is close to the limit, I would prefer to error on the greater psi than have problems in the future.
3) Do you have a rough estimate of pump size I will need?
4) Which CSV should I be using and what psi? Currently when pressure tank is full at 60 psi, showers are great and 50 psi is good, but 40 psi when pump kicks on is not so good.
5) Would a 50/70 psi switch work better for me and then have CSV keep me at 60 psi?
6) What gauge wire/cable will be needed in well case and from well case 90' to breaker panel in tank/filter house?
Thank you in advance for any help, suggestions or advice that you can offer.
