Based on your posts here you clearly have no idea what you are talking about. Or you have a sense of humor that I am just not getting.
Is your water coming from a well or is it city water.
In the case of a well:
Get your water tested to find out what is in the water. You will need a system to filter out what is in your water. It could be heavy metals, tanic acid, sulfer, Iron who knows. That is why you need to test it. Find out what is recommended by a professional. Then do your own research. Talk with your neighbors to see what they are doing and if it is working.
Bad well water will ruin your coffee maker, dish washer, hot water heater, washing machine, cloths. Leave deposits on your tub, shower sinks. Leave water spots on your car that are hard to remove.
In the case of city water:
It will have lots of chemicals in it that the water treatment plant puts in it. I would not drink that crap without some serious filtration. Reverse Osmosis is considered very effective.
You really should google this topic and get familier with your options before making a decision.
