I just recently purchased a house that has a Kinetico RO model 518. When I turn the shutoffs on I get no water out of the fresh water spout on the sink nor to a line running to the fridge. If you are unfamiliar with this model there is four different components.
There is a pre-filter with what looks like any normal filter inside a blue canister that goes to a black canister(which I can't open nor know what it does), a second filter which comes from the black canister which has a solid hard plastic enclosed filter inside a blue canister. The second filter is connected to the pressure tank. The pressure tank bladder is fine and had the proper pressure. From the second filter it feeds the fridge and fresh water spout on the sink.
I've removed both blue canister filters just to make sure those weren't the issue. I've figured out that the black canister is not letting water through. Is this clogged? If so can I clean it out. It looks like it has a hex screw in the bottom that could come out but not sure if I should do this. If I can't fix it is there anywhere I can get one. On the top of the canister there are some numbers of T-72 R8-6. On the bottom it has p327h0(I think).
Any help is appreciated.
