How many Showers are in the property?

Average Time in Shower in minutes.
Note: This figure is set to 10 minutes which refers to the UK average time in the shower. If you think this figure does not resemble you and your family, you can adjust the figure for a more accurate quotation.

Shower Output (litres per minute)

Every property has a different incoming flow rate depending on the mains water pressure.
