It will push more than 150 ft. The issue is, what is the flow rate? There will be about 5 psi pressure drop in 150 ft of 1" pipe at 10 GPM.Originally Posted by rick.a
As the pressure increases, the flow will drop off and the pressure drop will become insignificant.
If the house is a lot HIGHER than the pump, then it matters more. But it is still better for producing stable pressure in the house if the tank is in the house. It is important that the pressure switch be at the tank.
