ADVANCE 600KPA PVC Pressure Control Valve - 22mm 20 mm Plumbing Pipe  (Plastic)

Features: - Advanced PVC Pressure Control Valve - Brand: Unbranded - Type: Pressure Control - Pressure: 600KPA - Size: 22mm - This is a water pressure control valve fitted to the cold water supply to the geyser. How it works: - The purpose of the pressure control valve is to “balance” the water pressure of the hot and cold water supply to baths, showers and basins. - For a balanced system the cold water supply to baths, basins, showers etc must be taken off the supply between the pressure control valve and the geyser. - The pressure control valve reduces the cold water pressure to the same pressure of the hot water coming from the geyser. - Sometimes plumbers will locate the pressure control valve outside of the house – where the cold water supply enters the house. - This is fine. - Mostly however the multi-valve will be found in close proximity to the geyser. - The pressure control of the multi-valve is designed to release excess pressure and may therefore drip when water is drawn through the valve. - Each geyser must also be fitted with a pressure control valve. - As most geysers have a maximum working pressure it is vital that the pressure is controlled in order for the geyser to have a longer life span. - If no pressure control valve has been fitted then the geyser guarantee will likely not be honored.
