I was wondering some questions about najasat hopefully you can give me an answer to

1. If a item that has become najjis by something that require for it to be washed more than once like pig, dog or urine, after lets say the first wash is the water that leaks off of it considered najjis if it doesnt change color? or only if it changes color?

2- If our hand becomes najjis by one of those things mentioned above and we slightly rubb them together under a tap is that suffice to say its been washed twice?

3. Is tap water connected to a kurr source considered only kurr water or flowing/running water as well?

1. If it is washed with tapwater or water that is connected to Kurr after the removal of the actual najasah the water that comes out is Taher.
2. Washing it under the tap, suffices and for urine it is better to move the hand in and out twice.
3. If it is connected to city water, which is abundant, it would have the flowing water rules. If however, is connected to a small container above the house or the RV or a similar situation, it would not have the rules of flowing water.
