Your move
Look up your address in Whitney Nashville Water Works's service line inventory. If it says lead, galvanized or unknown, test your tap.

Ask Whitney Nashville Water Works whether it covers that cost before hiring anyone - many utilities now do.

The lead result guide covers how utilities pick the homes they sample. Small systems behave differently: why small systems go over more often.
