I am building a house and want to assure that I have good water pressure in my new home. My daughter built probably 500 ft away from me and the water pressure at the County water meter is 40 and at her outside faucet is 30. She complains about her water pressure. What is the best water pressure?
My new home may be as far as 1500 ft from the end of the road where the water meter will be installed (county water). My home will be 3000 sf with 2-1/2 baths with 2 showers. I have a HE washing machine, dishwasher and 1 sink in kitchen. I would like to know what size pipe I should install at the meter and up to the house. I guess gravity took 10 lbs of pressure from my daughter's house traveling the same distance as my house will be. I was hoping that if I install large enough pipe that it would not be necessary to have a booster pump and/or pressure tank.
thanks for your help.

for every 10' higher your house is than the meter you will loose 4.3psi STATIC pressure ~ depending on your actual elevation you may or may not need a storage tank and/or a pump ~ see an engineer or plumber if not sure
Then you will have the 'flowing' pressure loss due to friction of a long supply line.
Just as a GUESS I would run at least a 2" line for 1500' (assuming not too much elevation loss)
NOTHING except a pump/tank will make up for elevation loss.

A private water tower might be your best resolve. If you are in a developing area, you might want to consider a bigger tower to share. Your county engineers would be your best source of information.
Best Wishes

A Y Mc Donald makes an inline booster system which might be perfect for your needs.

I have used the AY Mcdonald pump....the customer had 35 lbs to start with....now they have 65
its the best way to go...then you can have normal pipe size and not worry about oversizing in an attempt to gain a couple of pounds...
40 is too low to start with......try taking showers with it
