What water flow rate is too high?

The ideal water pressure for an average-sized house is 10-15 litres per minute. Any less than 10 litres per minute and you have low water pressure. Any higher than 15 litres per minute and your water pressure is too high and could be causing damage to your pipes. In this case, call a plumber to come and fix things.
