I posted a question about my well awhile back concerning my pump not building pressure. After talking to well driller, he told me that the pump I have, being set at 450 feet, it will only produce about 40 psi or 2 gallons a minute. I have adjusted my shutoff switch so that my pump comes on at 40 psi and shuts off at 20psi. I did notice that when the pressure gets down to about 30 psi, that the gage jumps around and then in drops to 20psi where the pump then kicks on. I assume this is because of improper pressure in the actual tank. It has about 30 psi.. My question is this. The well driller told me if I want high pressure the the 20-40psi setting, that I would either need an industrial size pump set at 800 feet deep with galvinized pipe, or a 200 - 300 gallon storage tank into which the well pump would fill using a float valve to turn it on and off, and then a small pump of sorts to fill my pressure tank. The well drill has recommended this last method because of cost and ease of futrue maintance. If this is the best way to go, is it something that I can do myself, and if so what would I need and where could I get the supplies? Thanks
