What The Chlorination Conversion Is And Why It’s Happening

Castle Rock Water is performing routine distribution system maintenance that temporarily switches the disinfectant from monochloramine to free chlorine. The change began Monday, February 2, 2026, and is expected to continue through May. More details are available from the Town here.

This temporary switch is a common maintenance practice used to address increased biofilm in parts of the distribution system. While the Town notes that the biofilm is harmless, it can reduce the effectiveness of disinfection as water moves through pipes, which is why this conversion is being performed.

What You May Notice At The Tap And Why It Can Look Worse Before It Gets Better

During the first part of the conversion, customers may notice:

  • Discolored water
  • Taste and odor changes
  • Some pressure fluctuations

These changes are often tied to flushing and normal shifts in water movement, while the disinfectant changes are not. That movement can stir up harmless sediment, which shows up as cloudy or tinted water at the faucet.

Why Filtering Drinking Water Matters During The Conversion

Even if the water remains safe to use, many homeowners do not want to drink water that looks off or smells strongly of chlorine. A properly selected filtration system can improve clarity and taste and help reduce the “conversion effect” you may notice at the kitchen sink.

If you are sensitive to taste, cook at home, or want peace of mind, consider upgrading your filtration now.

How Brothers Plumbing, Heating, and Electric Can Help

The goal is straightforward: keep your drinking water cleaner, clearer, and better tasting during the conversion and beyond. Brothers can assess your plumbing setup, discuss which contaminants or effects matter most to you, and recommend filtration systems that address discolored water, chlorine taste, or odor, fitting your home and budget.

Here are common approaches, depending on your needs:

  • Under-Sink Drinking Water Filtration for the kitchen and primary drinking faucet
  • Whole-Home Filtration to improve water quality at multiple fixtures
  • Carbon Filtration to help reduce chlorine taste and odor
  • Reverse Osmosis Drinking Systems for higher-level drinking water filtration at a dedicated faucet

What To Do Right Now If Your Water Is Discolored

If your water is tinted or cloudy, run cold water for a few minutes. If it stays discolored, avoid washing whites and don’t use hot water until cold water runs clear. Sediment can settle in water heaters.

If your water quality changes often, a filtration system helps keep it consistent.

Get Clean, Reliable Drinking Water During The Conversion

Castle Rock’s conversion is temporary, but your expectations for drinking water are not. If you want clearer, better-tasting water now and a solution you can keep using long after the maintenance ends, schedule a water filtration consultation with Brothers Plumbing Heating and Electric.

Frequently Asked Conversion Questions

1. Is The Water Safe To Drink During The Conversion?

According to the Town update, the water remains safe for drinking, cooking, and cleaning during the conversion. You may still notice temporary changes in appearance, taste, or odor.

2. Why Does My Tap Water Look Brown Or Cloudy?

Discoloration is often caused by harmless sediment being stirred up during flushing and changes in water movement. It typically clears as conditions stabilize.

3. Will My Water Smell More Like Chlorine?

It can. A temporary switch to free chlorine may make the chlorine smell or taste more noticeable for some households.

4. How Long Will The Conversion Last?

The Town indicates the conversion began on February 2, 2026, and is expected to continue through May. For the latest timeline details, refer to the Town’s update.

5. What Is The Best Filtration Option For Drinking Water?

It depends on your goals. Many homes do well with an under-sink system, while others prefer reverse osmosis for higher-level filtration at a dedicated faucet.

6. Can A Whole-Home Filter Help With Discolored Water?

Yes, whole-home filtration can help reduce sediment and improve water quality at multiple fixtures. The best setup depends on how severe the issue is and where it shows up in your home.

7. Should I Avoid Using Hot Water If The Water Is Discolored?

If cold water is discolored, it is best to wait before running hot water, since sediment can enter the water heater. Once cold water runs clear, normal hot water use is typically fine.
