Problems in Your Water
Culligan diagnoses and fixes many different water issues. Here are some of the common water problems we can help you solve today with a professionally installed water softener or drinking water system.

01
Excessive Iron in Water
Excess iron is likely the culprit if you see rust on your appliance fixtures and drains. If left untreated, iron can eventually stain any surface your water comes in contact with.
02
Bad Tasting or Smelly Water
That foul odor coming from your faucet or showerhead is caused by Total Dissolved Solids (TDS) such as manganese, iron, and sulfur. Reverse osmosis technology will get rid of this smelly, bad-tasting water.
03
Hard Water Spots
Minerals from hard water can accumulate on clothes, dishes, glassware, and other household items. It also causes unnecessary wear and tear that could be solved with a Culligan water softener or water conditioner.

How Problem Water Filtration Works
Culligan filtration systems use specialized media to target specific contaminants. Iron filters oxidize and trap iron particles, while carbon filters remove chlorine and organic compounds.
Our systems automatically backwash to keep the filtration media clean and effective, ensuring consistent performance year after year.

Problem Water FAQs
What causes iron in water?
Iron in water typically comes from the ground. As water seeps through soil and rock, it can dissolve iron deposits. Well water is especially prone to iron contamination. Iron can also come from corroding pipes in older plumbing systems.
Why does my water smell like rotten eggs?
A rotten egg smell is usually caused by hydrogen sulfide gas dissolved in your water. This can occur naturally in groundwater or be produced by bacteria in your water heater or plumbing. A water test can identify the source, and proper filtration can eliminate the odor.
What causes orange or rust-colored stains?
Orange, red, or rust-colored stains on fixtures, laundry, and dishes are typically caused by iron in your water. Even small amounts of iron (as low as 0.3 parts per million) can cause visible staining. An iron filter can remove iron and prevent these unsightly stains.
Is well water safe to drink?
Well water safety varies depending on your location and geological conditions. Unlike municipal water, well water isn’t regulated or treated. It’s important to have your well water tested regularly for bacteria, nitrates, and other contaminants. Proper treatment systems can make well water safe and enjoyable.
What is a whole-home filtration system?
A whole-home filtration system, also called a point-of-entry system, treats all the water entering your home. This means every tap, shower, and appliance receives filtered water. It’s the most comprehensive solution for problem water issues affecting your entire household.
How often do filtration systems need maintenance?
Maintenance frequency depends on your water quality and system type. Most filtration systems need filter changes every 6-12 months. Whole-home systems may require annual service to inspect valves and clean or replace filter media. Culligan offers maintenance programs to keep your system running optimally.
Can I combine multiple treatment systems?
Yes, many homes benefit from a multi-system approach. For example, you might combine an iron filter with a water softener, or add a reverse osmosis system for drinking water. Your Culligan expert can design a comprehensive treatment plan that addresses all your water quality concerns.
How do I know which filtration system I need?
The best way to determine the right system is to start with a water test. Culligan offers free in-home water tests that analyze your water for a wide range of contaminants. Based on the results, your local Culligan expert will recommend the most effective solution for your specific water problems.
