The pump i'm looking at is:
1 HP Submersible 3-Wire Motor 20 GPM Deep Well Potable Water Pump by Everbilt.
I talked with another plumber and he said don't put the tank/s at the house, put them at the well and use 2 tanks. One for the control of the pump and one to boost psi. (one 44 gal tank with the pressure switch (40/60) in series that feeds the 2nd tank (44 gal with a working psi of 80psi). that way i won't wear out the pump and i will still have plenty of pressure at the house. Do you concur?
From 75'-100' the 1HP, 20 GPM pump will work, but the rest of that is bull. If you have a 40/60 pressure switch you will only have between 40 and 60 no matter how many or how few tanks you have. The pump makes the pressure, not the tank(s). The 40/60 switch shuts the pump off at 60, so 60 is the most you will see. Pressure doesn't just magically jump from 40/60 to 80 from one tank to another.
Now a 44 gallon tank only holds about 10 gallons of water, so you do need two of them to make a 20 GPM pump run for a minimum of 1 minute as required. The pressure in the house will go up and down from 40 to 60, 60 to 40, on and on, for every 20 gallons you use.
I know it is going to blow your plumbers mind, but the 4.5 or 10 gallon size pressure tank with a CSV will give you much stronger pressure than the old 40/60 pressure tank only method. Like I said the pressure and water come from the pump, not the tank. So when you have a little tank and a CSV, the pump comes on and gives you as much pressure as you need (like 80 PSI constant) for as long as you need it, even if you are in the shower for a month. Then when you are not using any water the CSV slowly fills the little tank and the pump shuts off. The CSV gives you 80 PSI constant, if that is what you want, no matter how much or how little water you are using. The water is going right past the tank, straight to the shower. It doesn't matter the size of the tank.
Most houses run the CSV at 50 PSI constant using a 40/60 pressure switch with a small tank. But as long as your pump will build the pressure, you can set it as high as you want. I set one recently for constant 140 with a 130/150 pressure switch for a house on top of a 200' tall hill. So you can have as much pressure as you want, but a tank is not going to give it to you.
