The 1/2'' Click Fit Adapter and Filter is simply pushed onto the tap provided with every model of FlexiTank or FlexiTank Pro. The filter resides within the length of the fitting. It reduces impurities in the water before it enters the pipework connected to the AQUAvalves trays and pots. This helps prevent the build up of sediment and the clogging of pipework. The outlet on the 1/2'' Click Fit Adapter and Filter allows the user to run 1/2'' pipe from the end of the fitting.
