We learned in October that the lead concentration in our tap water was higher than it should be. After waiting about seven weeks, the contractor arrived last week to replace our water supply line. We got a quote from the City's contractor to do our side of the line at the same time, and decided to go ahead with that quote ($2000+tax). It was a bit more than quotes we received from other plumbers in the summer, but the added money was worth it to not have to deal with a second contractor and to have a contractor that has been vetted by the City. We took a couple of photos of the work in progress, which shows the holes underneath our front lawn and the sidewalk.
