Does Your Home Have Lead Plumbing? Here's How To Tell

We get a lot of questions about lead service lines and how to tell if you have lead pipes, and we thought that it would be worth putting together an article that talks about some of the lesser known places where lead can exist in residential plumbing. Most people are surprised to learn that up until 2014, EPA allowed lead exist in fixtures & valves used for drinking water lines!

The Evolution of “Lead Free” Plumbing

When the Safe Drinking Water Act (SDWA) was amended in 1986, it mandated that residential plumbing could not use any pipe, pipe fitting, solder, flux, or fixture that was not “lead free.” While the term “lead free” seems pretty straightforward, the law allowed for the definition of "lead free" to evolve. The chart below shows allowable lead levels in solder, pipes, fittings, and fixtures through the 25+ years that lead was phased out of plumbing. It's worth pointing out that, it wasn’t until very recently (2014) that all pipes/fittings/fixtures used for drinkable water were required to contain negligible amounts of lead.

Maximum Levels of Lead Allowed in Residential Plumbing 

 Years  Solder/Flux Pipes, Fittings, Valves
Before 1986 50% 100%
1986-2014 0.2% 8%
After 2014 0.2% 0.25%

Note: Things like toilets, urinals, bidets, tub fillers, shower valves are excluded from these regulations 

How to Determine If Plumbing in Your Home Is Lead Free

Solder: Unfortunately, there is no easy way to visually tell how much lead is in soldered joints after the connection is made. If you are getting plumbing work done, it's ok to ask your plumber to see the package for the solder that they are using. It should prominently say “lead free” on it.

Pipes/fittings: Because there are certain applications (toilets, showers, tub fillers) where plumbing components are allowed to contain lead, you can still buy lead-containing plumbing components at the hardware store. We have seen many applications in customers' homes where lead-containing components were mistakenly used in an application that required lead free components. Anything that complies with the 2014 lead free standard is clearly marked with some sort of "LF" or checkmark label to indicate that it meets the most recent lead free standard:

What To Do If Your Home Has Lead Plumbing

As the US has become increasingly aware of lead contamination in drinking water because of the ongoing crisis in Flint, recent violations in large cities like Pittsburgh, and longstanding lead problems in old cities like Chicago and New York City, more and more people are asking what they can do to minimize their family's exposure to lead.

The best way, bar none is to:

If you are unable to use a rated filter, or if the filter you use does not protect against lead (like most pitchers and fridge filters), you can take the following steps to minimize exposure:

  • Allow your faucet to run for at least 2 minutes before collecting water for consumption (drinking/cooking/washing food). Doing so allows the water sitting in the pipes to flush out and be replaced by fresh water flowing through the large mains.
  • Only use the faucet at a slow flow rate when collecting water for consumption. Doing so minimizes the amount of lead particulates that can be swept into the stream and carried to the faucet.

As always, we encourage everyone to take advantage of Hydroviv's "Help No Matter What" technical support policy, where we answer questions related to drinking water and water filtration, even if you have no desire to purchase our products. Drop us a line about lead pipes in homes at support@hydroviv.com, or use our live chat function.

3 Years of Hell: Reflections From a Flint Resident

Analies Dyjak @ Thursday, April 27, 2017 at 10:31 pm -0400

LuLu Brezzell  |  Guest Contributor

Editor's Note: This article is part of an initiative to include stories on our blog that connect water quality issues to the everyday lives of real people. To raise awareness of the 3 year anniversary of the beginning of the Flint Water Crisis, Flint resident LuLu Brezzell describes the roller coaster ride that her family and fellow Flint residents went through once they realized that their water was not safe to drink. Ms. Brezzell was gracious enough to share her story with our audience, and was not paid to do so.

Fear

Fear, the feeling that takes over when you are told that your water source that flows into our home was filled with lead and bacteria. The same water we have been using to drink, cook with, and bathe. Fear, the feeling of knowing that your children may have been exposed to an invisible, tasteless, odorless poison that can cause irreversible damage. As a parent, there is no greater fear. 

This is the same fear that I'm sure every single member of my community felt.

What Happened?

Three years ago, as part of a cost-cutting measure, a state-appointed emergency manager made the decision to switch Flint's drinking water from Detroit's municipal water to the Flint River. Flint's water plant hadn’t treated raw water in decades, never mind the fact that it was not equipped to manage industry standard corrosion control measures that would prevent corrosive river water from eating away at Flint's aging infrastructure.

On the day of the water supply switch, the emergency manager, mayor and other council members all gathered at the Flint Water Plant, and ceremoniously toasted each other with glasses of the new tap water.

Who could have expected that this toast would mark the day that our city lost its access to clean safe water?

Visible Symptoms Hinting At A Much Larger Citywide Problem?

Soon after the switch, my youngest child, who wasn’t even two years old, started to have serious issues with her skin, including persistent rashes that OTC treatments couldn't stop. She was eventually prescribed a steroid ointment that slathered onto her, and wrapped her up like a mummy with plastic wrap. It was horrible, in part because we had no idea what was causing the problem.

Here's the short answer: It was the water she was bathing in.

Shortly thereafter, we had the US CDC, EPA, MDEQ and other agencies all in our home, taking water samples and asking questions in an attempt to diagnose what was causing these issues. We weren't alone in this, it was happening all over our City. It was like watching a horror movie, where you have no idea what was going to happen next.

Our city was in the midst of a widespread water contamination emergency.

An Inspiring Call For Help

My other daughter (8 years old at the time) became very concerned with what she saw happening in Flint, and felt like she needed to do something. Here I am feeling helpless and my child is begging me to let her do something to help.

So help we did! We participated in protests and rallies to raise awareness of the water crisis. We would go out and find people passing out water and jump in a volunteer with them. We made videos and took pictures that we could share on social media.

One day we heard about a bus traveling from Flint to Washington, DC for the congressional hearing for Governor Rick Snyder. My daughter thought that if we were going to go to Washington, DC... it would probably be worth it to write a letter to (then) President Obama. About a week before the trip, she sent the letter, and I was careful to remind her that President Obama was very busy, and that he probably wouldn't be able to read it. The trip to DC came and went as planned, and a good learning experience.

But soon after we returned to Flint, we got a call...

From the White House.

President Obama was touched by her letter and wanted to come to Flint to meet her and to see first hand what was being done for the water crisis.

Flint In The National Spotlight

When that letter was released so much changed, because The Flint Water Crisis was now in the spotlight. Up until that point, I had been begging outside groups to come in and do testing (we didn't trust the testing that the city was conducting). Once the story hit the national news, things changed. We were getting emails and messages offering us water filtration systems, testing, and other products. It was so hard to keep up with everything. I was overwhelmed but grateful that finally it felt like someone was listening and wanting to help.

Navigating Conflicting Voices In A Storm Of Information

Unfortunately, some people saw the media spotlight and chaos as an opportunity to make a name for themselves, or even worse... profit from the situation.

Like anyone, I wanted answers and was willing to listen to everyone who claimed to have a solution that could fix our problem. It's easy to look back and say that I should have focused on certain opinions and ignored other voices, but it's important to remember that at the time... it was complete chaos, and even though we were grasping at straws, we were hopeful that the next straw grasped could be the solution we were looking for. 

Looking back, I feel fortunate that while others were making names for themselves, an outsider with no ties to Flint was willing to remain in the shadows while helping me weed through and understand all of the information. 

What Lies Ahead For Flint's Tap Water?

It's been 3 years since Flint made the fateful water supply switch that turned an entire city upside down.

Unfortunately, it's much easier to make a mess than it is to clean it up. 

Our city's pipes are irreparably damaged, and we're learning that it's not as easy as digging them up and replacing them. Precautions must be taken in the meantime to ensure that no addition exposure occurs as the pipes are swapped out. It's also important to remind ourselves that replacing the service lines will not do anything to fix any lead-containing solder, valves, or plumbing fixtures inside our homes. The official recommendation is that we continue to filter our water for lead, but I know that some residents continue to rely on bottled water.

Another problem that has gone largely unpublicized is that the city is having a hard time maintaining disinfectant levels in the water, which means that some areas have noticeably high chlorine levels while other parts of the pipe network have virtually no residual chlorine to keep the water sterile.

Right now, several city and state officials are under investigation for the alleged roles they played in the Flint water crisis.

Tap water is something that most of us take for granted, but producing clean water at the municipal level is more complicated than most realize. Because of what we have gone through, I don’t think I will ever trust tap water ever again. 

What's Changed In Our Home?

In the year since the letter not much has changed regarding how we use water. We still don’t use the tap water at our house for consumption. Showers are limited to 2 minutes because of how sensitive my families skin is to the water, even when filtered. Bottled water is still a very big part of our everyday lives. As much as an inconvenience as it is to constantly open up bottles of water it has almost become second nature. 

On the activism and awareness front, my daughter is still doing her part to raise awareness of water quality issues, and to be a voice in support of quality science.

Things To Know Before Replacing Your Home's Lead Service Pipe

6.1 million homes in the United States still use have a functioning Lead Service Line to deliver municipal water into homes. The EPA recently announced that it will allocate $2.9 billion in the Bipartisan Infrastructure Law funding to states, Tribes, and territories for lead service line replacement in 2022. While lead pipe replacement programs can be a great long-term solution to eliminate a source of lead contamination, it doesn’t make all problems go away. Here's the lead water service pipe information you need to know if you are considering replacing your home's lead service pipe:

Lead Contamination in Flint, Michigan Drinking Water

Analies Dyjak @ Monday, July 25, 2016 at 1:26 pm -0400

Eric Roy, Ph.D.  |  Scientific Founder

***11/20/2019: Note from Eric. It’s been recently brought to my attention that the July 16, 2015 date on this article may have been incorrect, and that the correct publication date is October 14, 2015. We’ve changed the date listed on the article to reflect this.***

I wanted to take a make our readers aware of a largely unreported disaster that is underway in Flint, Michigan. The residents of Flint, MI are being poisoned by lead in their tap water because the municipality messed up... big time. In this post, I'll focus on the science behind lead contamination, the facts (as we know them) of what happened in Flint, and touch upon another incident in recent history where a similar thing happened.

​All water has impurities in it. Most impurities are harmless (e.g. dissolved oxygen, minerals), some are harmful (e.g. lead, arsenic, mercury).

Impurities typically enter tap water in 3 ways:

  1. Some are found in the source water (e.g. naturally occurring minerals)
  2. Some are deliberately added as part of the treatment process (e.g. chlorine)
  3. Some are picked up along the way from the treatment facility to the tap. 

Lead is almost never found in source water at dangerous levels, and nobody deliberately adds lead to their water supply, because it's toxic. Lead can, however, be be introduced to tap water as it flows from the treatment facility to the tap.

How is Flint’s drinking water picking up lead in transit?

It’s pretty straightforward: Nearly all homes with plumbing installed before the 1986 use lead-containing solder to join copper pipes. Lead can also be found in residential plumbing fixtures manufactured before 1998. Additionally, some older homes use lead service line pipes to connect water mains to homes. Proper water quality testing (e.g. pH, chloride, toxic metals) and corrosion control practices (e.g. monitoring chloride levels, maintaining a slightly alkaline pH, adding corrosion inhibitors) are what keep residents with older plumbing and service connections safe from lead contamination. This is not unique to Flint. Unfortunately, it's not always done correctly, and residents suffer.

In Flint, as well as other places where high lead levels have leached into municipal tap water (e.g. Washington, DC in the early 2000’s), monitoring and corrosion control measures failed, which allowed lead to dissolve from pipes/fittings/fixtures and poison the residents.

What changed in Flint to cause the lead contamination problem?

In 2014, Flint stopped buying its tap water from Detroit (which has proper corrosion control measures in place), and began collecting their water from the Flint River as part of a plan to switch to a different water supply. During the changeover process, the municipality failed to implement effective corrosion control measures, and the corrosive water allowed lead to leach from lead-containing plumbing. Because proper water quality monitoring procedures were not in place, the Lead problem was not widely discovered until recently.

What Now?

Flint has announced that it will resume buying water from Detroit, which gets its raw water from Lake Huron and has proper monitoring and corrosion control measures in place. This is a great first step, but it's important that Flint keeps monitoring their water for lead, because the pipes can continue to leach lead while the corrosion control measures build up the protective layer on the inside of the pipes. The length of time this takes will depend on the degree of corrosion, and whether or not Flint's water will have "boosters" of the anti corrosion chemicals.

Until lead levels drop, residents are being urged to use a quality water filtration system that effectively removes lead. Contrary to some of the information out on the internet... boiling water before use does NOT decrease the amount of lead. It is critical that Flint residents use a filter that effectively removes lead, and also changes the cartridges on a regular basis. I would expect that the filtration capacity (in gallons) for lead would be much lower than the manufacturer claims, because the gallon capacity ratings were determined using water with much lower lead concentrations than what is currently being measured in Flint.

Even though there is a plan moving forward, this type of incident almost certainly caused harm to some residents Flint, and the areas most affected by it were probably homes with older plumbing. Even though lead contamination is odorless and tasteless, it has devastating effects on human health. Since Flint began using the Flint River as a water source, numerous children have tested positive for high levels of lead in blood, and a number of schools have recently shut down water fountains due to high lead levels. When a similar lead contamination issue occurred in Washington DC between 2001-2004, stillbirths shot up during the affected years (Edwards, 2013). As was the case in Washington, DC, the full extent of harm likely will not be realized for several years.

*** Update June 2016: We are getting a lot of questions from Flint residents about what to do now. The message that we want to communicate to people in Flint is that you now have a world leader in Mark Edwards actively working with the city to help fix the problem. There is quite literally no person on earth with more credibility than Dr. Edwards on this topic, and nobody with a better track for helping people who have been affected by this sort of disaster. Please listen to him with open ears. He will not lie to you. There are a lot of far less credible people who are looking to elevate their status by saying things that will resonate with residents. Please do not listen to them. This problem will take longer to fix than it took to create, but understand that you now have the top expert on earth working on the problem.
