From what I have seen from commercials, it should fix the hard water problem especially if you use a well. They showed people putting salt into the hot water heaters.

The main problem with hard water for most people is its tendency to cause limescale buildup in pipes and appliances. This can reduce water flow, damage plumbing systems, and decrease the efficiency of water-using appliances such as dishwashers and water heaters. Additionally, hard water can make soap less effective, leading to difficulty lathering and potentially leaving a film on skin and hair.

The tap water in Wirral is classified as hard water, containing elevated levels of minerals like calcium and magnesium. This hardness can cause limescale build-up in appliances and affect the taste of water. Consider using a water softener if you find the hardness to be a problem.
Hard water deposits minerals in the body. If enough of those minerals build up, you can get kidney stones or gall bladder stones. Also hard water does not allow soaps and other materials to be washed off the skin creating dry and flaky skin.
Yes, the halting problem is not NP-hard, it is undecidable.
Reverse osmosis water treatment can effectively remove minerals that cause hard water, such as calcium and magnesium, leading to a softer water. However, the process may not address the root cause of hard water in the plumbing system, so regular maintenance and monitoring may still be required to prevent scaling and buildup.
A problem can be demonstrated to be NP-hard by showing that it is at least as difficult as any other problem in the NP complexity class. This is typically done by reducing a known NP-hard problem to the problem in question, showing that a solution to the problem in question would also solve the known NP-hard problem.
