Anyone know what year lead pipes were phased out?
They have been continuously phasing them out since the first ones were installed.
When in doubt, hire a licensed professional
Although I was required to learn how to repair them during my apprenticeship, they were not being installed in new construction in 1970.
If you have never made a mistake, you probably haven't done much.
"With passage of the Safe Drinking Water Act Amendments of 1986,5 installation of lead water pipes was finally prohibited nationwide."
It actually makes the water taste great! That and I loved the protective layer it puts on my lead fillings on meh teef. Part of the reason I have to use a catheter at age 40.
