Lead Pipes: Testing and Replacement Guide

Lead in drinking water represents one of the most serious—and often overlooked—home health hazards. While lead pipes were banned in new installations in 1986, many older homes still contain lead components that can contaminate your family's water. At Judd's Plumbing, we help Arizona homeowners navigate the process of identifying, testing, and replacing lead plumbing to ensure safe drinking water for every household member.

Why Lead Pipes Are a Health Emergency

Lead is a potent neurotoxin with no safe level of exposure. Its effects are particularly severe on children and pregnant women:

Children's Health Impacts:

Developmental delays and learning difficulties
Lower IQ scores and attention disorders
Hearing and speech problems
Impaired growth

Adult Health Impacts:

Cardiovascular problems and increased blood pressure
Kidney damage and dysfunction
Reproductive issues
Neurological effects

How Lead Enters Your Drinking Water

Lead rarely comes from the water source itself. Contamination occurs when water corrodes lead-containing components in your plumbing system:

Lead Service Lines: The pipe connecting your home to the municipal main (common in pre-1950 homes)
Lead Solder: Used on copper pipes until banned in 1986
Brass Fixtures: Many contain small amounts of lead, especially older models
Galvanized Pipes: These steel pipes can accumulate lead particles from upstream sources

How to Identify Lead Pipes in Your Home

The Visual Inspection Test

Find your service line entry point (usually in basement, crawlspace, or near water heater)
Use a magnet: Lead pipes are not magnetic (galvanized steel pipes are)
Look for these characteristics:
- Color: Dull gray that shines brightly when scratched with a key
- Shape: Often has a swollen joint near connections
- No Stampings: Lead pipes typically lack manufacturer markings
- Softness: Lead is easily scratched or dented

Common Locations to Check

Service entry point where water enters your home
Basement plumbing near the water meter
Older sinks and fixtures with original connections
Basement ceilings where plumbing runs between floors

Professional Testing Methods

When visual identification is uncertain, Judd's Plumbing uses these methods:

Water Quality Testing

First Draw Test: Samples taken after water sits in pipes 6+ hours
Flushed Test: Samples taken after running water for several minutes
Laboratory Analysis: Precise measurement of lead concentration

Physical Inspection Methods

Pipe Sampling: Taking small samples for laboratory analysis
Camera Inspection: Viewing internal pipe conditions
Professional Assessment: Evaluating entire plumbing system

Immediate Actions If You Suspect Lead Pipes

Use only cold water for drinking and cooking (hot water dissolves lead faster)
Flush pipes by running water for 1-2 minutes if unused for several hours
Consider using a certified water filter (look for NSF Standard 53 for lead removal)
