Expert Answer
We can detect the hard water by some home made obseravtion. Common problems associated with hard water are :
1. It shows poor washing machine performance. Clothes washed in hard water often look dingy and feel scratchy or stiff. Continuous laundering in hard water can damage fibers and shorten the lifespan of clothes.
2. We can observe whitish scale deposits in pipes, water heaters, tea kettles, pots, silverware and dishes as well as calcification of taps and shower-heads.
3. There will soap curd and scum in washbasins and bathtubs.
4. Bathing with soap in hard water leaves a film of sticky soap curd on the skin, which may prevent removal of soil and bacteria.
