Common water problems in Merrillville
Hard water problems
Hard water results from high levels of calcium and magnesium in water. Hard water minerals stick to everything water touches, and do more than leave an unsightly residue - they can actually harm your home and cost you money. Learn more about hard water.
Common hard water problems include:
- Stains and buildup on sinks, shower heads, and dishes
- Dry skin and hair
- Costly long-term damage to water appliances

Notes from a few happy customers
“To Culligan, Shane and Andy were out at my house and changed my filters and then changed my inside pipes, for my big boy filter system. They both were fantastic and timely and very clean in my house, they did a great job, they are very great workers!!! You are very lucky to have them working for you."

“I’d just like to say thank you to Shane and Tyler they put in our water system, they were so excellent in explaining everything about the water, what to expect, what to do if we encountered a problem, and how everything works. Finally they assured us that they’re only a phone call away. I’m so excited about the new system, we couldn’t drink or cook with our other water, and our pots and dishes came out stained and smelly. I am so looking forward to the change.”
