How to Safely Treat Water with Lead

Ask This Old House plumbing and heating expert Richard Trethewey gives a tutorial on why lead can be found in home drinking water and the best methods to combat it.


1. Richard explains in some places lead can still be found in pipes that lead into homes around the United States. It can leech into that piping and into your drinking water.
2. To test your water, you can purchase a home lead test kit from a home center, or you can have a water quality expert run a detailed test.
3. Most pitcher filters and whole house sediment filters will not treat for lead, however some faucet style filters can remove lead.
4. To ensure that no foreign contaminants reach your drinking water, Richard recommends installing a point of use Reverse Osmosis system, which ensures everything except pure hydrogen and oxygen are filtered out.
