Hard water rarely announces itself. It shows up as a crusty showerhead, a water heater that starts popping, or a faucet cartridge that gives out years early. If you live in Carmel, Fishers, Westfield or anywhere in Hamilton County, there's a very good chance your home has it.
Here's how to spot it, what it's doing inside your plumbing, and what you can do about it.
Why hard water is so common around here
Much of Central Indiana sits on limestone. As groundwater moves through that rock, it picks up calcium and magnesium, and those minerals are what make water "hard." City treatment makes water safe to drink, but it isn't designed to take the hardness out, so it flows straight into your home.
That means a brand new build in Westfield and a 1960s ranch in North Indianapolis can have the same problem. Homes on private wells in the outlying parts of Hamilton and Boone County often see even more minerals, sometimes along with iron.
10 signs your home has hard water
Some of these are easy to see. The later ones are easy to blame on something else.
White, chalky crust on faucets, showerheads and the base of fixtures.
Soap that won't lather and shampoo that seems to take twice as much.
Spotty glasses and dishes, even right out of the dishwasher.
Film on shower doors and tile that comes back days after cleaning.
Showerheads and aerators that clog and spray unevenly.
Dry skin and dull hair after showering.
Popping or rumbling from the water heater, which is sediment on the bottom of the tank.
Hot water that runs out sooner than it used to.
Water pressure that slowly drops at certain fixtures.
Appliances that quit early, like dishwashers, washers, ice makers and coffee makers.
What it's doing where you can't see it
In your water heater
The water heater takes the worst of it. When water is heated, minerals drop out and settle to the bottom of the tank as sediment. That layer sits between the burner or element and the water, so the heater runs longer to do the same job. Over time you get noise, slower recovery, higher energy use and a tank that wears out before it should.
Tankless heaters deal with it too. Scale builds up inside the heat exchanger, which is why they need regular descaling in hard water areas.
In faucets, valves and fixtures
Scale collects in faucet cartridges, shower mixing valves, toilet fill valves and pressure regulators. That's often the real reason behind a dripping faucet, a shower that won't hold a steady temperature, or a toilet that keeps running.
In your pipes
Mineral buildup narrows the inside of pipes little by little, especially older galvanized steel lines. The result is a slow loss of flow that can be mistaken for a bigger pipe problem.
How to find out for sure
The signs above are a strong hint. To know how hard your water actually is, you need a test. Test strips from a hardware store give a rough reading. Your city water provider may also publish hardness numbers for your area.
When we test water at your home, we can tell you the hardness level and whether iron is also present, which matters when choosing the right equipment. Well water homes especially benefit from a real test before anything gets installed.
What you can do about it
Flush your tank water heater once a year to clear out sediment before it hardens.
Descale a tankless heater on the schedule the manufacturer recommends.
Soak showerheads and aerators in white vinegar to dissolve scale.
Install a water softener. This is the fix for the cause rather than the symptoms. A softener removes calcium and magnesium before the water reaches your heater, fixtures and appliances.
Salt-free "conditioners" can reduce how scale sticks to surfaces, but they don't remove hardness minerals. For the hardness levels common in Hamilton County, a traditional softener usually gives the best protection.
When to call us
If you're seeing several of these signs, or you've just replaced a water heater and want to protect it, give us a call. We'll test your water, explain what the numbers mean and show you your options for water softeners and filtration. If your water heater is already noisy or struggling, we can check it during the same visit and let you know whether a flush or a water heater repair makes sense.
Your plumber gives you options and a price before any work starts.
FAQ
Is hard water safe to drink?
Yes. Calcium and magnesium aren't a health concern at the levels found in household water. Hard water is a plumbing and appliance problem, not a drinking water problem.
Does boiling water remove hardness?
Not in any useful way. Boiling can drop some minerals out as scale, which is exactly what happens inside your kettle and water heater, but it doesn't soften the water coming out of your taps.
Can hard water ruin a new water heater?
It can shorten its life considerably. Without softened water or regular flushing, sediment starts building from the first day. A softener and a yearly flush go a long way toward getting the full life out of a new heater.
Why do I still have spots if I already have a softener?
The softener may be out of salt, set wrong for your hardness level, or due for service. Check the salt first. If the brine tank is full and you still see scale, the unit likely needs to be adjusted or repaired.
Do homes on well water have harder water?
Often, yes. Wells in the outlying parts of Hamilton, Boone and Hendricks County can be quite hard and may carry iron too. A water test tells you exactly what you're dealing with so the right equipment can be matched to it.
