The average pressure in South African households is 4 Bars. However, the pressure in the municipal water main may be much higher and depends on factors such as the height of the reservoir and friction in the delivery pipes. The pressure could be 8 Bars, which would eventually damage household fittings and appliances. A Pressure Relief Valve (PRV) is a device which reduces the pressure at its inlet to a lower pressure at its outlet.

Try to verify that sufficient water pressure is available when selling an installation that requires a minimum level. The information may not be easily accessible, but at least the customer has been made aware of the issue and can follow up appropriately.

The law requires that each household plumbing system be fitted with a Pressure Reducing Valve.
