Lead water service lines in Laval
In Laval, a house built before 1967 may have a lead water service line. To check, the City advises finding the main water inlet pipe (usually at the front, near the concrete foundation): lead is grey, doesn’t ring when tapped and doesn’t attract a magnet. If in doubt, call a plumber. The City replaces lead lines on the City side when they leak and gives priority to replacing water mains that have them. If the line is lead and someone is pregnant or there are children under 6, Laval’s public health department recommends a filter certified to NSF/ANSI 53 for lead reduction, or bottled water.
