Now that some municipalities are adjusting the pressure of their water systems, what is the impact on the compliance of sprinkler systems?

In recent years, when demand is low, the City of Montreal (like many other municipalities) has reduced the pressure of drinking water at the outlet of its production plants and pumping stations.
