Hard water or high mineral content water supply: how to recognize that you need a water softener by simple visual inspection of fixtures in the building . Here is a description of what to look for and where to find it in diagnosing hard water conditions.

Hard water is not just an aesthetic concern in the shower. Very hard water can clog pipes [photo of scale build-up in a water pipe] and water heating equipment (especially tankless coils such as the ones we show here) leading to costly repairs.
Hard water is not normally health concern people although the treatment of hard water using a conventional ion-exchange (salt) water softener can, especially if improperly adjusted, place salt (NaCl) into the water supply at a level which people on low-salt or no-salt diets may wish to avoid.
We discuss this point further at HOW WATER SOFTENERS / CONDITIONERS WORK.
Separately at WATER TESTING GUIDE we describe easy tests you can make to actually measure the hardness of the building water supply.
Here are some visual clues that the water supply at a building is hard
There is a water softener installed - look for the water softener treatment tank and salt tank, usually installed close to where water enters the building or close to the water pressure tank and pump controls if a private well is in use.
Hot water pressure is noticeably less than cold water pressure in the building.
Since minerals precipitate out of hard water faster when the water is heated, we expect hot water piping to clog with minerals faster than cold water piping.
Signs of tankless coil clogging from hard water: When a tankless coil is installed, since that's where our water is the hottest, often the tankless coil clogs before other plumbing materials.
Our photo at left looks up into the mouth of a bathroom faucet spout, showing minerals deposited by three years of exposure to hard well water.
Stained plumbing fixtures such as the bath tub shown in this photo often tell a lot about the history of a building as well as the condition of its water supply.
