Universal Citation: KS Admin Regs 49-50-5
Current through Register Vol. 43, No. 12, March 20, 2024

When local water pressure is in excess of 80 pounds per square inch (55.2kPa), an approved pressure-type regulator preceded by an adequate strainer shall be installed and the pressure shall be reduced to 80 pounds per square inch (55.2kPa) or less. Potable water systems, up to and including 1 1/2 inch (31.1mm) regulators, shall be constructed to prevent pressure, on the building side of the regulator, from exceeding the main supply pressure. Approved regulators with integral by-passes shall be acceptable. Each regulator and strainer shall be in an accessible location. The strainer shall be readily accessible for cleaning without removing the regulator or strainer body or disconnecting the supply piping. All pipe size determinations shall be based on 80 percent of the reduced pressure.
