Hello floogle-ga,
Static Water Pressure - the pressure that exists in a piping system
when there is no flow; measured in pounds per square inch (PSI).

Residential Static Water Pressure is usually in the range of 40 to 100

 “Residential static water pressure (no water flowing) is usually
between 40 pounds per square inch and 100 psi. Somtimes the pressure
in the city main is too high and each house will have a pressure
reducer to bring the pressure to under 100 psi. Usually static
pressure is not our problem when we design a sprinkler system. The
problem is more often a water flow rate of under 10 gallons per
Rodda And Sons

“The King County Health Department and the Uniform Plumbing Code both
recommend residential water pressures to be in the range of 30 psi to
80 psi (70 ft to 185 ft).”

plumbing lines may burst, or damage may occur to appliances.”
