Applications / Recommended Pump / CSV / etc. for New House
« on: August 05, 2021, 02:38:13 PM »
I'm building a new house in a rural area. First time on a well, and would appreciate some help with recommended pump, CSV, pressure tank, etc.. I'm sold on the CSV concept, but not sure about best pump and sizing. I want to put in the best system for good pressure, water quality, and the absolute least maintenance issues going forward.
- Shallow well has been dug and 36" I.S. diameter vertical "casing" installed
- 5' deep water in the well casing
- TOP of water in the well casing is 20' below level of future CSV valve and pressure tank
- 2nd/3rd storey fixtures could be an additional 15'-20' above CSV valve and pressure tank
- Distance from well casing to house inlet is approx. 250'
- Plan to set submersible pump vertically at bottom of well casing, so pump intake will be approx. 3.5' below top of water level (23.5' below future CSV valve)
- So 3.5' pumpable water x 3' I.S. diamater = 185 US Gal. water storage
- Measured recovery rate of well = 7-8 US gpm
- Planning on 1-1/4" (not 1") HD polyethylene (165 psi?) pipe from pump to house because of 250' distance
- House ~ 2,000 sq.ft., 4 bedrooms, 2-1/2 baths
- Peak Demand = 14 gpm? (based on charts on Cycle Stop website, etc.)
- Total daily water requirements = 300+ US gal. per day
Would like to use a submersible pump with flow inducer sleeve, CSV valve, and small pressure tank. CSV valve and pressure tank will be located in conditioned basement of the new house.
Based on word-of-mouth from neighbors, it's highly likely I will need some sort of hydrogen peroxide and carbon filter system to take care of sulphur smell and possibly iron content. I haven't had detailed water analysis yet, but I'm sure there will be some sort of filter system added to the system.
1.) Do you agree with my planned 1-1/4" HDPE pipe size, or do you recommend something different?
2.) Do you agree with my Peak Demand 14 gpm assumption?
3.) Do I want 10 gpm pump, or 15 gpm pump, or something different?
4.) Do I want 3/4 hp (because of distance), or bigger or smaller?
5.) Do I want 2 wire or 3 wire pump with CSV valve? (I'm assuming 1 phase, 230 volt)
6.) Meyers pumps have a good reputation around here, but I'm in no way partial to them. I looked at the Meyers "Predator Plus" series (their best I think), for example #2ST72-15PLUS-P4, 15 gpm 3/4 hp. Or do you recommend Grundfoss instead?
7.) From what I've read on the Cycle Stop website, I think I need the CSV1A valve with 10 US Gal. pressure tank.
8.) Do I want to set CSV desired pressure at 60 psi (pressure switch 50/70) or higher?
9.) I notice the 10 gal. pressure tank is factory pressurized to 35 psi. Can this be changed to 60 psi?
Thank you
