static water pressure
In French: pression statique
Definition
Water pressure in the pipes when no tap is running, read with a gauge screwed onto an outdoor tap. It limits which heads you can use and how far they throw; too high makes heads mist, too low leaves gaps in coverage.
Also called

Other names in French
