|In response to Re: lead in old galvanized pipe|
Even if they were, in your case the interior of the pipe has long since been lined with a layer of rust or mineral effectively sealing the pipe from contact with the water. Is it rust or black stains? Black stains can be caused by a reaction between the heater's magnesium anode and soft water. You often tell by the presence of small black specks in the sink after the water is allowed to seep out slowly. Rubbing your finger across them will produce a black streak.
: Recently, our water softener company representative, tested our water and found that it was soft, although we still get rust stains in our sinks and bathtub. He concluded that the rust was probably caused by our old, galvanized pipes. He said that galvanized pipes used to be manufactured with a percentage of lead and suggested that we test our water for lead. Is it true that galvanized pipes were once made consistently with a percentage of lead?
