Hard water and your plumbing
Hard water carries calcium and magnesium. When it's heated, those minerals drop out as scale inside water heaters, on faucet aerators and shower heads, and inside pipes. Scale makes water heaters work harder and wear out sooner. Mike explains how hard water hurts plumbing.
Softeners
A water softener swaps hardness minerals out of the water before it reaches your fixtures. It sits on the main line, usually in the basement, and needs salt topped up periodically.
Filtration
Filters range from an under-sink unit for drinking water to a whole-house system on the main line. The right choice depends on what you want removed. For well water, start with a lab test.
