When you turn on your sink faucet, does it initially produce water with a brown tint to it? Are you concerned about the health effects of lead or copper in your drinking water? Was your home built before 1988 when lead sodder was used to connect water pipe systems? Over time, copper and galvanized pipes accumulate significant amounts of rust and sediment causing corrosion. Such corrosion can result in harmful contaminants in your drinking water.
