Lead Pipes Are Still a Problem: What Homeowners Can Do While Cities Replace Old Water Lines

Key Takeaways

• Many cities are replacing old lead service lines, but the process can take years. 

• Lead can enter drinking water through old service lines, plumbing, fixtures, or solder. 

• You cannot see, smell, or taste lead in water, so testing is the best way to know if there is a problem. 

• Homes built before 1986 may have a higher chance of lead-related plumbing concerns. 

• Boiling water does not remove lead. 

• A properly selected drinking water filter, including certain reverse osmosis systems, can help reduce lead at the tap. 

• Filter replacement and maintenance are important for keeping a system working properly. 

Why Lead Pipes Are Still a Concern

Lead in drinking water is still a serious issue for many homes in the United States. Cities and water utilities are working to identify and replace old lead service lines, but these projects do not happen overnight. In some areas, replacement can take years because utilities must locate old lines, schedule work, secure funding, and coordinate with homeowners.

That means some homes may still have lead service lines or older plumbing materials even while replacement programs are underway. For homeowners, the important question is not just whether the city is working on the problem. The question is what you can do now to help reduce possible lead exposure in your own home.

Lead is especially concerning because it is not something you can detect by looking at your water. Water can appear clear and still contain lead. It usually has no taste or smell, which is why testing and proper filtration are so important.

How Lead Gets Into Drinking Water

Lead usually enters drinking water after the water leaves the treatment plant. It can come from older plumbing materials between the water main and your faucet.

Common sources include:

• Lead service lines connecting the home to the water main 

• Older household plumbing 

• Brass faucets or fixtures 

• Lead solder used in older plumbing systems 

• Disturbance from construction, pipe repairs, or service line replacement 

Lead can be more likely to enter water when water sits in pipes for several hours, such as overnight or while no one is home during the day. It can also become a bigger concern after plumbing work or nearby construction, which may disturb old pipes and release lead particles.

Step 1: Find Out If Your Home May Have a Lead Service Line

Start by contacting your local water utility. Many utilities now have service line inventories or online lookup tools that can show whether your home’s service line is listed as lead, non-lead, galvanized, or unknown.

You can ask your utility:

• Has my service line material been identified? 

• Is my home scheduled for inspection or replacement? 

• Does the replacement include both the public and private side of the line? 

• Are filters recommended during or after replacement work? 

• Should I flush my water after nearby construction or pipe repairs? 

Homes built before 1986 deserve extra attention because older plumbing materials were more likely to contain lead. Even if the city replaces its portion of the service line, older indoor plumbing or fixtures may still need to be checked.

Step 2: Test Your Water

Testing is the best way to know whether lead is present in your drinking water. Some local water utilities offer free or low-cost lead testing. You can also use a certified laboratory for more detailed results.

When testing, follow the instructions carefully. Lead levels can change depending on how long water has been sitting in the pipes, whether nearby work disturbed the plumbing, and which faucet is tested.

A helpful test may include a first-draw sample after the water has been sitting unused for several hours, as well as a flushed sample after the tap has run for a short time. The kitchen faucet is often the most important place to test because it is usually where drinking and cooking water comes from.

Step 3: Use Cold Water for Drinking and Cooking

If lead is a concern, use only cold tap water for drinking, cooking, coffee, tea, baby formula, and ice. Hot water can dissolve metals from plumbing materials more easily than cold water.

Boiling water does not remove lead. In some cases, boiling can make the problem worse because water evaporates while metals remain behind. If you are concerned about lead, use properly filtered cold water or another safe water source instead of relying on boiling.

Step 4: Flush Water After It Has Been Sitting

If water has been sitting in your pipes for several hours, flushing the tap may help reduce lead levels before use. Run cold water until it becomes noticeably colder, or follow the flushing instructions provided by your local water utility.

Flushing is not a complete solution, but it can be a helpful step in some homes. It may be especially important after plumbing repairs, water main work, nearby construction, or service line replacement.

Step 5: Choose the Right Drinking Water Filter

Not every water filter is designed to reduce lead. A basic pitcher, refrigerator filter, or sediment filter may improve taste or reduce particles, but that does not automatically mean it is suitable for lead reduction.

When lead is a concern, look for a drinking water filter that is designed and tested for lead reduction. Point-of-use filters are commonly used because they treat the water at the faucet where you drink and cook.

Reverse osmosis systems are also a popular choice for drinking water because they use multiple filtration stages. Many under-sink reverse osmosis systems include sediment filtration, carbon filtration, and an RO membrane to help reduce a wide range of contaminants.

For many households, an under-sink reverse osmosis system is a practical option because it focuses filtration where it matters most: the kitchen sink.

Whole House Filter or Reverse Osmosis for Lead?

A whole house water filter and a reverse osmosis system serve different purposes.

A whole house water filter treats water as it enters the home. Depending on the system, it may help reduce sediment, chlorine, odor, discoloration, and other general water quality concerns. Whole house filtration can also help protect appliances and improve water throughout the home.

A reverse osmosis drinking water system treats water at a specific faucet, usually in the kitchen. This is often the better focus when the main concern is drinking water contaminants such as lead.

In many homes, the best setup may include both: a whole house system for general water quality and an under-sink reverse osmosis system for drinking and cooking water.

Step 6: Replace Filters on Schedule

A water filter only works properly when it is maintained. Old or clogged filters may lose effectiveness, reduce water flow, or fail to perform as expected.

Follow the recommended replacement schedule for your system. If your home has high sediment, heavy water use, or known contamination concerns, filters may need to be changed more often.

For reverse osmosis systems, this may include replacing sediment filters, carbon filters, post-filters, and the RO membrane as needed. Keeping up with maintenance helps protect water quality and keeps the system running efficiently.

Step 7: Be Careful During Pipe Replacement Work

Lead service line replacement is an important long-term solution, but the work itself can temporarily disturb old pipes and release lead particles. If your street, neighborhood, or home service line is being replaced, ask your water utility what precautions they recommend.

You may be advised to use filtered water for drinking and cooking, flush your taps after the work is completed, clean faucet aerators, or replace filter cartridges after heavy disturbance.

This is especially important for homes with babies, young children, pregnant women, or anyone with health concerns.
