Say you have a 1.3 psi pump, 1 psi is said to go 3 feet. Now doesn't the width of the hose matter in this equation? The wider the hose the heavier the amount water is being pumped? Or does that not matter at all and is based on flow rate?
It would stand to reason a 6 foot wide house would need more psi to pump water up 3 feet then a 6 inch wide hose?
