Assume that my skin or my cloth became najis due to direct wet contact with ritually impure thing. Now, to make it paak, I put the cloth or skin under continuous flow of water under a tap. Now, the water that flows through skin or coth, also becomes najis? If some other thing touches that water, that thing will also becomes najis?how far can it get transferred? Thanks.

If something became Najis after coming in the contact with Najis thing and that najasat transfer through wetness if you washed twice it become paak
