The correct location depends on where the water comes from and how the house’s water system is designed.
A common arrangement is:
Water Source → Storage Tank → Pump → House Piping → Taps & Showers
The pump takes water from the storage tank and supplies it into the house at the required pressure.
In other systems, the arrangement may be different depending on the property, water source and local plumbing configuration.
A simple Example
Imagine a house with a water tank and bathrooms on different floors.
Without sufficient pressure, an upstairs shower may have weak water flow.
A correctly selected pump installed after the appropriate water source can increase the pressure supplied to the house, helping water reach the upper floors more effectively.
