Put a stop to low water pressure with this pump. It is perfect for transforming your unsatisfactory shower into a powerful and invigorating shower that you'll never want to leave.

Positive Head

A positive head shower pump is designed to be gravity fed, therefor it needs a 'head' of distance (at least a metre) between the pump and the bottom of the cold water cistern. The gravity feed 'kick-starts' the pump, pushing water straight through to your shower. 

Where the water level in the cold storage tank is below the level of the shower outlet a negative head situation exists. Specialist Automatic Negative Head pumps to overcome this problem are available from Grundfos.
