How do you tell if your home has lead pipes?
Determining if your house has lead pipes is crucial for ensuring the security of the water your family consumes.
Lead pipes were typically used in homes constructed before the 1980s. If your house is older, it could be a lead source for plumbing. Here are a few steps that you can take to find out the presence of lead pipes:
- Test for magnets: Lead isn’t magnetic, so if one can apply a magnet to the pipe but it does not stick, it’s composed of lead.
- Water test: If you’re worried lead pipes may contaminate your house, you could get your water tested for lead. A certified lab is capable of doing it.
- Find indications: Certain pipes might contain markings or letters that tell what materials they’re made of. As you can see, “Lead” or “Pb” (the periodic symbol in the table that represents lead) is a clear indication.
- Review the house’s documents or blueprints: Sometimes, records from the house or blueprints and the disclosure statement you received when you purchased your home might include the plumbing materials.
- Hire an inspector or plumber: If you’re not sure, an experienced inspector or plumber can precisely determine if your house is equipped with lead pipes.
How can I test for lead contamination in my plumbing?
The first step in testing for lead is to call your local water company. Most water companies are willing to test water at no cost or for a nominal cost. If this is not an option, it is possible to hire a state-certified accredited laboratory to conduct the test.
The Environmental Protection Agency (EPA) offers a list of accredited laboratories. It is essential to select an accredited lab since they have the required skills and equipment to measure lead levels accurately.
When testing, it’s essential to take a sample of the first water taken in the morning or after a prolonged period without use.
The “first-draw” sample is most likely to determine the extent to which lead leaches out of your plumbing. The lab will supply you with sample containers and specific instructions on properly collecting the sample.
If your tests reveal lead levels higher than 15 parts per billion (ppb), which is the EPA’s threshold for action, you must do your best to limit the risk of exposure.
This could include flushing your pipes before using the water, using only cold water for cooking and drinking, and using a certified water purifier to eliminate lead.
The most efficient method of removing lead contamination from pipes is to change fixtures and pipes that contain lead.
What are the risks of continued use of lead plumbing?
Lead is a very toxic metal that could cause serious health issues, particularly among children. Lead is a poisonous metal that can leach into drinking water through plumbing fixtures and pipes made of lead and also into the air through paint containing lead.
The dangers of the continued use of lead plumbing comprise:
- Behavioral and developmental issues: Lead poisoning can lead to behavioral and learning problems, developmental delays, and neurological harm. This is particularly concerning for children under the age of 6, as their nervous systems and brains are still in crucial stages of development.
- Reproductive problems: Lead exposure has been associated with reproductive issues, including reduced fertility and an increased risk of miscarriage. These consequences can deeply impact individuals hoping to conceive and start a family.
- Increased risk of heart disease: Studies have shown a correlation between lead exposure and a higher likelihood of developing heart disease. The toxic effects of lead on the cardiovascular system emphasize the importance of minimizing lead exposure to safeguard against potentially life-threatening cardiac conditions.
- Link to cancer: Exposure to lead has been linked to an increased risk of certain cancers, such as brain and kidney cancer. This association highlights the need to address and mitigate lead contamination to protect individuals from the devastating effects of cancer.
How much lead is safe in drinking water?
Lead can trigger serious health issues if it is present in excessive amounts and is introduced into your body through drinking water or other sources.
It could cause harm to the kidneys and brain and affect your body’s production of blood vessels, which transport oxygen to all body parts.
The EPA has set the maximum lead contaminant in drinking water to zero since lead can be dangerous to human health at low levels of exposure.
The EPA’s action level for lead levels in water supplied to public water systems is 15 ug/L.
What are the signs and symptoms of lead poisoning from plumbing?
Due to its subtle and vague initial symptoms, lead poisoning, which can happen when lead from plumbing leaches into drinking water, frequently goes unnoticed.
Lead buildup in the body over time can result in serious health problems. The symptoms may change depending on the person’s age, exposure duration, and intensity.

How quickly might you get lead poisoning from lead pipes?
Lead poisoning is a condition that occurs when lead accumulates within the body, usually over time. Even tiny amounts of information can trigger serious health issues.
Lead poisoning can be triggered rapidly or gradually, depending on how much lead you’re exposed to and the length of time you’re told.
In some instances, you will experience symptoms of lead poisoning within just a few days after exposure. In other cases, it could take several months or even years for symptoms to show up.
What are the effects of lead poisoning on people?
Lead poisoning can cause extreme health issues as well as behavioral and learning issues, resulting in sudden and permanent brain damage and cognitive impairments.
High levels can cause damage to the nervous system and kidneys in adults and children.
Extremely high levels of lead could result in seizures, numbness, and even death. Signs of lead poisoning can include stomach cramps, headaches, muscle or joint pain, constipation, insomnia, fatigue, irritability, and a loss of sexual desire.
It can also create serious health issues for everyone in the age range. Here, we’ve explained the effects of this drug in depth:
The effects of lead poisoning on pregnant women as well as unborn infants
Lead exposure can severely affect pregnant women and their babies who are not yet born. Lead may traverse the placental barrier, so if the pregnant woman is exposed to lead, the fetus may be too.
It could result in premature birth, a smaller birth weight, and a slower growth rate. In some instances, high exposure levels may result in miscarriages.
For mothers, lead poisoning could cause high blood pressure as well as other complications during pregnancy.
After birth, babies exposed to lead in the uterus could experience developmental delays and learning difficulties.
The effects of lead poisoning on children
Children are especially susceptible to the adverse effects of lead poisoning. Even the lowest levels of lead among children may cause learning and behavioral issues, a lower IQ, hyperactivity, slower growth, hearing loss and anemia.
In high concentrations, lead poisoning in children can trigger seizures, apathy, and, in rare cases, even death.
Children’s bodies absorb lead faster than adults’, and lead can be more dangerous to their brains because their chemistry and nervous system are developing.
The effects of lead poisoning on adults
For adults, prolonged exposure to lead can cause various health problems. This includes cardiovascular issues, elevated blood pressure, and an increased risk of heart disease, hypertension, and stroke.
It could also lead to kidney damage and decreased fertility. The neurologic effects can include reduced memory function, cognitive decline, mood issues, and, in more severe instances, peripheral neuropathy.
The consequences of lead poisoning can be irreparable, so early detection and prevention are crucial.
Can you filter out lead from water?
Removing lead from your drinking water is possible, and it is a good idea if your water supply is infected with lead. There are many methods of water treatment to make it easier to remove all lead contamination from water sources.
There are only some water filters that are equally effective in removing lead, which is why it’s crucial to select a filter that is specifically designed to reduce lead.
Find a product that meets Standard 53 of NSF/ANSI for lead reduction. This means that it has been tested and passed strict tests to confirm that it substantially reduces the amount of lead in the air.
Filtration methods that remove lead are:
- Filters made of activated carbon: These filters effectively remove lead, depending on their quality and certification. They’re typically used in pitcher filters as well as faucet-mount filters.
- Reverse osmosis systems: These systems utilize semipermeable membranes to eliminate various contaminants, which include lead. Although these systems are more expensive and consume some water, they are generally very efficient.
- Distillation devices: Distillers bring water to a boil and then capture the steam as it cools and leaves lead-based contaminants. They can also be more costly and consume more energy.
