Nashville plumbing questions
Where does Nashville's water come from?
From the Cumberland River, treated by Metro Water Services at the K.R. Harrington and Omohundro plants.
How do I protect pipes during a Nashville freeze?
Insulate pipes in crawl spaces and attics, close crawl-space vents during cold snaps, disconnect hoses, and let a faucet drip on the coldest nights. If a pipe bursts, shut the main valve first.
Should I get a sewer scope before buying a Nashville home?
For older homes or ones with big trees near the line, yes. A camera inspection costs little compared with a sewer repair you didn't know about. See sewer camera inspection.
