Does my Pittsburgh home have a lead service line?
Older homes may. Check where the line enters the basement (lead is dull gray and scratches to shiny silver), or look up your address with Pittsburgh Water, which has been replacing about 1,500 lead lines a year.
Can I get help paying to replace a lead line in Pittsburgh?
Depending on income, customers may qualify to have the private side replaced at no cost through Pittsburgh Water's program. Check with the utility before hiring a plumber for this job.
Is Pittsburgh water hard?
Pittsburgh Water describes it as moderately hard, so some scale on fixtures and in water heaters is normal.
