This pump is virtually silent when in use,
because the speed is regulated depending on the flow rate of water from the
shower. This reduces noise output considerably, whilst also reducing wear on
the pump. For an electric shower:
the pump is activated by a flow sensor positioned in the cold water supply
pipe.
For a mixer shower: a flow sensor is
required for both hot and cold water supply pipes - an additional sensor
must therefore be added to the kit shown in the image below. |
