Apart from the substantial cost of installlation, and the ongoing expense of maintenance, sprinklers in houses are totally impractical. The main reason can be found on that website mentioned above:
That kind of flow from a domestic water supply simply isn't going to happen.Residential Sprinklers typically use only about 60 litres of water a minute.
Well it shows you should not be commenting on this then.
Just done a house with the required flow rates.
Most maybe not, new builds with new mains installed ( remember the roads all dug up a while back) will. As refurbishments with the new mains running.
