What is a positive head booster pump?
The best way to remember the key differences between a positive and negative booster pump is to think push or pull.
A positive booster pump pushes the feed of water into your shower.
​
It does this by relying on gravity to feed the water from your water tank into the pump. This flow kickstarts the impellers which then pump the water to the shower.

This reliance on gravity means that your water tank needs to be at least 3 feet and 3 inches (990mm) above the shower head.
This allows enough room for the water to pick up speed and kick the pump into action.

What is a negative or universal head booster pump?
Negative (Universal) booster pumps work a little differently. Instead of relying on gravity, a negative (universal) booster pump pressurizes everything in the pipe from the pump to the mixer valve ensuring the pump starts each time.

This type of pump is the best choice for when your shower head is at the same level or higher than the cold water storage tank.

These pumps are used in loft conversions, residential flats and home renovations.
