Mr. Contractor: Water Pressure Regulators should be installed when supply pressure exceeds 60psi (14.1 bar). 
  The only accurate way to determine the supply pressure in a building is to test the 
  pressure on the premises. Watts 276H300 Test Gauge offers a quick and simple way 
  to test water pressure.
