You turn on your kitchen faucet, fill a glass, take a sip, and immediately recoil. The water smells and tastes like a swimming pool. Your first thought is “did something get contaminated?” Your second should be “I need to understand what’s happening.” If your tap water smells like bleach, At Repipe Solutions Inc, we get these panicked calls from homeowners across the Greater Houston Area constantly. Here is exactly what that smell means and what to do in the next 15 minutes.
What the Smell Is
99 percent of the time, it is chloramine, a combination of chlorine and ammonia that Houston Public Works uses to disinfect the municipal supply. The city periodically increases chloramine levels, especially during quarterly “free chlorine conversions” when the system is flushed. During these events, residents across Bellaire, West U, The Heights, and the surrounding Greater Houston Area suddenly report strong bleach odors from every faucet.
Is It Dangerous?
For healthy adults, short-term exposure to higher chloramine levels is not considered directly dangerous to drink. However, chloramine is a known respiratory irritant, particularly during hot showers when it off-gases into the air. People with asthma, eczema, sensitive skin, or aquarium fish need to take action immediately.
What to Do Right Now
First, confirm it is a citywide event by checking the Houston Public Works website or calling 311. Second, avoid long hot showers until the conversion period ends. Third, if you have pet fish, add a chloramine-neutralizing conditioner to the tank before the next water change. Fourth, if anyone in your home has breathing issues, open bathroom windows and run exhaust fans during every shower.
The Long-Term Fix
A whole home water filter with catalytic carbon. Standard activated carbon does NOT effectively remove chloramines — you need catalytic carbon specifically designed for ammonia-based disinfectants. Repipe Solutions Inc installs catalytic carbon whole home systems engineered specifically for Houston’s chloramine levels. One system, one install, no more tap water that smells like bleach. Call us today at 832-662-4288 for emergency water quality testing anywhere in the Greater Houston Area.
One More Practical Tip
While you wait for the city’s chloramine levels to normalize, fill a large pitcher or glass carafe with tap water and leave it uncovered on the counter for 24 hours. Chloramine does not dissipate as easily as pure chlorine, but leaving water to breathe does reduce surface taste and smell noticeably. It is not a permanent fix, but it buys you drinkable glasses while you line up a proper catalytic carbon install.
