Clean. Flush. Consume Cold.

Clean, Flush and Consume Cold are daily actions all customers should take to ensure the highest quality of water is coming out of your tap, especially if there is the possibility of lead in your plumbing system and after a disruption of service.

As a standard practice the USEPA recommends these actions (clean, flush, consume cold) to reduce possible lead exposure in drinking water. In some situations, a water system repair/replacement may temporarily increase lead levels in water and/or cause discoloration.


If you know of sources of lead in your home, school or business, there are additional actions you can take, and partners you can gain information and assistance from.





Clean your faucet aerator screens regularly. Small particles of solder and other material can accumulate in faucet aerators and in some circumstances can release lead into the water. Aerators should be cleaned at least twice a year, and more frequently after work on your plumbing system.

Flush your cold water lines before consuming water when water has not been used for 6 or more hours. The goal is to have cold, fresh water from the main in the street come out of your tap before drinking the water. To flush the plumbing, run water until you feel a temperature change then run water for an additional 30 seconds to 3 minutes. The time depends on the length and diameter of your service line. The farther your home is from the street, the longer you need to flush. When in doubt, flush it out.

  • Customers who received a purple door hanger referencing lead should perform a 30-minute full house flush when their water service is restored and/or their home is connected to a new water main. learn more

Always use cold water for cooking, drinking and preparing baby formula. Hot water corrodes pipes faster and is more likely to contain lead. If you need hot water for food or drinks, get water from the cold water tap then heat the water.

Older faucets may contain higher levels of lead. Faucets manufactured and sold in the U.S. after 2014 are considered “lead-free” and must contain less than 0.25% lead in areas that come into contact with water. Cost: $ to $$$ per faucet

Point-of-use treatment devices include water filtering pitchers and filters that attach directly to faucets used for water consumption. The device should be certified to remove lead for potable water use by a certifying organization such as the National Sanitation Foundation International (NSF), Underwriters Laboratory (UL), or Water Quality Association (WQA). Filters must be maintained and changed according to the manufacturer’s instructions or users run the risk of increasing their lead exposure. Cost: $ to $$$ + regular replacement filter costs.

Cleveland Water encourages customers to replace customer-owned lead service lines, especially when we are replacing city-owned lead service lines. Cleveland Water now offers to replace customer-owned lead service lines every time we replace the city-owned portion of a lead service line. The highest risk for lead exposure is when partial lead service lines are left behind. When customers replace their portion of a lead service line, Cleveland Water will replace our portion of the service line if it is lead. For more information, contact our Lead Inquiry Line at 216-664-2882. Cost: $$$$ One-time cost of approximately $60-200 per foot of service line.

Cleveland Water cares about your family’s health. We take action to prevent lead exposure from known lead sources in plumbing systems. However, according to the Ohio Department of Health, the most common source of lead exposure in our state is dust from deteriorating lead-based paint used on homes and buildings before the 1978 ban on lead paint. Lead-contaminated dust settles on floors, windowsills, and toys and can also impact the soil outside homes. Lead was historically used in a wide variety of products including paint, ceramics, plumbing materials, solders, gasoline, batteries, ammunition, jewelry and cosmetics. For additional information about lead poisoning prevention and where to have your blood tested for lead:

Many groups are working to eliminate lead from paint and other potential exposure routes. Below are links to entities based on the following categories:

Health Information

Lead exposure can impact everyone, particularly babies, developing fetuses, and children age 6 and younger, because their growing bodies absorb more lead than adults’ bodies and their brains and nervous systems are more sensitive to the damaging effects of lead.

According to the Agency for Toxic Substances & Disease Registry, children can absorb 40-50% of an oral dose of lead that is dissolved in drinks or food. By comparison, adults will generally only absorb 3-10% of lead that is consumed. Once lead is deposited into the respiratory tract, 95% can be absorbed into the blood (see ASTDR report).

Bottle-fed infants younger than 6 months are the most likely to be impacted by lead in water because their diet primarily consists of re-constituted formula and they are unable to move about on their own. Children age 6 months and older are more likely to be impacted by lead dust because they touch many surfaces that adults do not touch; younger children suck on thumbs and put other items in their mouth that may have been exposed to lead dust.

Even low levels of lead in the blood of children can result in behavior and learning problems, lower IQ, hyperactivity, slowed growth, hearing problems and anemia. Chronic lead exposure (long-term low-level lead exposure) is more common than acute (one-time very high dose); however lead exposure can negatively impact all people.

A person who is exposed to lead over time may feel abdominal pain, constipation, depressed, distracted, forgetful, irritable, nauseous/sick, fatigued, and have impaired concentration. Lead exposure can also have reproductive effects including miscarriages, stillbirths, reduced sperm count, and lead can pass from other to developing fetus.
