Pressure Reducing Valve
Water main pressure can exceed 200psi. Municipal and private water supply companies use pumps and pumping stations to boost water supply pressures. This allows them to maintain adequate water pressure for fire fighting, high-rise buildings to overcome loss of pressure and to maintain water supply in water towers and supply tanks. Water pressure reducing valves, on domestic systems where the municipal water main’s pressure exceeds 80psi, are required. Higher pressures could rupture pipes, damage fixtures/components and injure the people using them.
