Post a pic, including all the pipes,..
RO and Di arrived today from pure freedom, read the instructions, connected up, flushed for 2 hours like it said without Di then connected Di. Water at the tap is 385 ppm water in holding tank is 407 ppm? im baffed
what colour hose do you have going into the tank?
What colour hoses do you have?I have a white hose going from the DI vessel into the tank, Blue going from the outlet from the RO into the DI and a Red one for the waste.
Sounds to me you have then the wrong way around and your chucking the good stuff down the drain, be aware of the flush tap as that can also be confusing
