Water Quality Solutions for Indianapolis Homes and Businesses
 If you live in Indianapolis, you’re dealing with hard water. According to Citizens Energy Group, the city’s water hardness ranges from 200 to 425 parts per million — that’s 12 to 25 grains per gallon, depending on your neighborhood and the treatment plant serving your area. Anything above 10 grains per gallon is considered “very hard.” Most of the Southside sits well above that threshold.
Â
Hard water isn’t a health risk on its own, but it does real damage over time. It coats the inside of your pipes, wears out your water heater faster, leaves mineral deposits on every surface it touches, and makes soap and detergent less effective. The good news is that a properly sized water treatment system can solve these problems at the point of entry, protecting your entire home from the source.
Â
We’ve been installing and servicing water quality systems across the Greater Southside Indianapolis area for over three decades. We’ll test your water, explain what we find, and recommend a system that fits your home and your budget — not the most expensive option on the shelf.

Our Water Quality Services
Water Softener Installation
Water softeners remove the calcium and magnesium minerals that cause hard water. For Indianapolis homes, a softener is one of the most impactful upgrades you can make. It protects your pipes, extends appliance life, reduces soap and detergent use, and eliminates white scale and spots left by hard water. We size every system to match your household's water use and hardness level. Water Softener Installation
Whole-House Water Filtration Systems
A whole-house filtration system treats every drop of water that enters your home — every faucet, every shower, every appliance. We install carbon filters, sediment filters, UV treatment systems, and chemical- and contaminant-reduction filters. If you're concerned about what's in your water beyond hardness, this is the system to consider. Water Filtration Systems
Reverse Osmosis Drinking Water Systems
Reverse osmosis is a point-of-use system, typically installed under your kitchen sink, that produces clean drinking water by pushing it through a fine membrane that removes dissolved minerals, chemicals, and contaminants. It's the highest level of filtration available for residential use, and it pairs well with a whole-house softener for complete water treatment. Reverse Osmosis Systems
Not Sure What Water Quality Service You Need?
Here’s what your water might be telling you.
White Scale or Crusty Buildup on Faucets and ShowerheadsÂ
- Possible causes: Hard water mineral deposits (calcium and magnesium)
- Likely service: Water Softener Installation
- Urgency: Schedule this month — scale buildup gets worse over time and can restrict water flow
Spots on Dishes, Glasses, and Shower DoorsÂ
- Possible causes: Hard water minerals left behind after evaporation
- Likely service: Water Softener Installation
- Urgency: Schedule at your convenience — a softener eliminates this problem at the source
Dry Skin, Itchy Scalp, or Dull HairÂ
- Possible causes: Hard water prevents soap from rinsing completely, leaving a film on skin and hair
- Likely service: Water Softener Installation
- Urgency: This is one of the first things homeowners notice improves after a softener is installed
Water Tastes or Smells Off (Chlorine, Metallic, Earthy)
- Possible causes: Chlorine from municipal treatment, dissolved metals, organic compounds in source water
- Likely service: Water Filtration System or Reverse Osmosis
- Urgency: Schedule a water test — we'll identify what's causing it and recommend the right filter
You Want Cleaner Drinking Water at the Tap
- Possible causes: Dissolved solids, trace chemicals, chlorine, or general concern about water purity
- Likely service: Reverse Osmosis System
- Urgency: Schedule at your convenience — an RO system gives you filtered drinking water without buying bottled water
Why Indianapolis Homeowners Invest in Water Treatment
Protect Your Plumbing and Appliances
Hard water scale builds up inside your pipes, water heater, dishwasher, and washing machine. According to the U.S. Geological Survey, about 85% of American homes have hard water, and Indianapolis sits well above the national average. A water softener stops scale at the point of entry before it reaches anything in your home.
Spend Less on Soap and Cleaning Products
Hard water makes soap less effective. You end up using more detergent, more shampoo, and more dish soap to get the same results. Softened water lathers better, rinses cleaner, and means you can use less product across the board.
Water That Tastes Better and Feels Better
A softener handles the hardness. A filtration system handles the chemicals and sediment. An RO system produces drinking water that's cleaner than most bottled brands. The combination is noticeable from the first day — in how your water tastes, how your skin feels, and how your dishes look.
Long-Term Value for Your Home
Water treatment systems reduce wear on every fixture and appliance that uses water. They can extend the life of your water heater, reduce plumbing repairs , and lower your energy costs. For homes on the market, a water softener is a practical selling point that buyers in Central Indiana recognize.
What Our Neighbors Are Saying
If you want to work with an honest plumber who will execute the job with excellence, then you need to come to Parkhurst Family Plumbing! We had a major water leak and they got us in contact with a company that would help us with the insurance process while working quickly to help resolve the plumbing issues. We have had him install our kitchen sink four years ago, install a dish washer, install some toilets, replace the outside water spigot after it was leaking, reinstall the garbage disposal, fix the burst pipe (which required getting in the slab) and also fix a bad installation of a pipe in our bathroom by the home builders 20 years ago. He does an outstanding job and will be honest through the process. He’s also come out after hours and all times of the day and NOT charged an arm and a leg. Thanks, Larry! I should have left a review a long time ago — he can do it all!

I contacted Larry around 11am because the installers for our new stove said we needed to have a licensed plumber come out and change our stoves gas line. Larry came out later the same day and had everything fixed and even helped install our new stove for us. I highly recommend reaching out to him if you find yourself in need with your plumbing because he really saved my sanity by being here so fast and helping us.

Save thousands and use Parkhurst. The big dogs in town will rob you blind!! Apples to Apples quote proves that. One of the few honest business left in Indianapolis. I will 100% use them in the future.
February 25, 2026
We had a new experience in our home last night. We used the master tub, only to come downstairs and find an absurd amount of water coming from around the air vent in the kitchen ceiling! I immediately called Larry, and he was able to come over bright and early this morning to check the problem. Larry quickly found the issue: come to find out, we had a crack in the overflow catch! Larry was able to get it fixed and did a great patch in the wall, too! We’ve never had a plumbing issue before this, but if we ever do again, we definitely know who to call!

INDIANAPOLIS WATER: WHAT'S ACTUALLY IN IT?
Indianapolis tap water runs 12 to 25 grains per gallon — anything above 7 is considered hard, according to Citizens Energy Group. That mineral load is why water heaters, fixtures, and appliances wear out early across the Southside.

Water Quality Questions
How hard is Indianapolis water?
Very hard. Citizens Energy Group reports hardness ranging from 200 to 425 parts per million, or 12 to 25 grains per gallon. Anything above 10 grains per gallon is classified as very hard. A water softener is the most direct solution.
Is a water softener worth it in Indianapolis?
For most Indianapolis homes, yes. Given how hard the water is here, a softener protects your pipes, extends appliance life, reduces soap and cleaning product use, and eliminates hard water stains. The investment usually pays for itself over time through reduced repairs and lower product costs.
What's the difference between a softener and a filtration system?
A water softener removes calcium and magnesium (the minerals that make water “hard”). A filtration system removes chemicals, sediment, chlorine, and other contaminants. Many Indianapolis homeowners benefit from both — a softener for the whole house plus an RO system for clean drinking water.
How much does a water softener cost in Indianapolis?
It depends on the size of your home and your water hardness level. We provide a written quote after testing your water and assessing your needs. We also offer flexible financing through Wisetack, including 0% interest for 12 months with online pre-approval.
Do you offer water testing?
Yes. We test your water to measure hardness, identify contaminants, and determine the right treatment for your home. Testing helps us recommend the system that actually solves your problem, rather than guessing.
