Why your home’s pipes matter
The public system can be fine while your building’s own pipes change the water. That gap is why this site never claims to test your kitchen tap.

The last stretch is yours
Town mains stop at the property. After that: service line, indoor pipes, then the fixture. That stretch belongs to the building — not the public water system — so system records do not describe it.
When it can matter
- Age — older buildings may have older pipes and fittings.
- Sitting water — overnight or after vacation, water sits longer in pipes.
- Fixtures — the tap itself is part of the path.
What you can do
- Ask your city about service-line records or replacement programs for your address.
- If you want certainty about your tap, have it tested.
A clean public system record does not prove your building’s pipes are fine.
The public file cannot see inside your walls.
