Ask a Question
  • Hi. Our geyser can't handle the 4 bar pressure supplied by the pump. It started leaking. Is there any thing we can do to rectify this to bring the pressure to 2 bar instead.

    Dear valued customer,

    The simplest solution (yet the more expensive) is to install a VSD onto the pump. The cheaper option would be to purchase a pressure tank that can absorb the pressure delivered by the pump. One could also just buy a new, less powerful pump as a replacement.

  • Hi. how do i adjust the pressure setting to increase on the LEO PS-04B Automatic Pump Controller


    Good day Morne

    The PS-04B regulates the pressure automatically, and can not be adjusted.

    The pre-set starting pressure is at 1.2Bar and closes on the maximum pressure of the pump/ closed valve.


    If the application requires different starting and stopping pressures please refer to the Switchmatic controllers which can be adjusted
