The problem is the heat increases the amount of lead dissolving in the

Was the water distilled or acidic? If not, the minerals in the water
build up a layer over the walls of the pipe that covered the solder and
the copper. If it didn't, the water would dissolve not only the lead,
but the copper pipe.
