Quick Answers Before You Go
How do I know if my water is hard?
Your house usually tells you first: spotted glassware, white crust on faucets, stiff towels, and soap that will not lather. To be sure, measure it. Hardness is reported in grains per gallon, and an inexpensive test strip or an in-home test will give you a working number. Start at our Testing desk.
Is hard water safe to drink?
Hardness itself is calcium and magnesium, minerals your body recognizes, and hard water is generally considered safe to drink. The trouble it causes is practical: scale in appliances, dingy laundry, and dry skin. If you have health questions about anything else in your water, get it tested rather than guessing.
How often should I test a private well?
Standard guidance is at least once a year, and again any time something changes: a flood, nearby construction, plumbing repairs, or a new taste, smell, or color. City water is tested by your utility; your well is tested by nobody unless you do it.
Do salt-free softeners actually work?
They work at the job they are designed for, which is scale reduction, not softening. Salt-free conditioners change how minerals behave so scale sticks less; they do not remove hardness, so spotting and soap behavior stay about the same. Our honest comparison walks through who should pick which.
Why does my water smell like rotten eggs?
That is usually hydrogen sulfide gas. If only the hot water smells, the water heater's anode rod is a common culprit; if hot and cold both smell, the source water is the more likely origin, especially on wells. A test pinpoints it before you spend on treatment.
What should I do before buying any water equipment?
Test first, always. A real hardness and contaminant picture keeps you from buying a solution to a problem you do not have, and it gives you the numbers to size equipment correctly. Then read the relevant buyer guide so the showroom cannot out-jargon you.
