Do this now: a leaking or dead water heater

1. Smell gas: leave and call Piedmont Natural Gas or 911 from outside. Do not relight anything.
2. Leaking: turn the gas control to off, or switch off the water heater's breaker if it is electric and you are standing somewhere dry.
3. Close the cold-water valve on the pipe feeding the tank to stop more water coming in.
4. Move boxes and rugs away and photograph the water for your insurer.
5. Write down the brand, model and age from the label; the plumber will ask.

Is it urgent? Leaks, gas and no hot water

A tank leaking from the bottom, water near the electrical panel, or any gas smell needs help today; a unit that only runs lukewarm can usually wait a day. A leak from the tank itself usually means replacement, which ConsumerAffairs puts at $1,200 to $2,500 for a tank in Nashville. A leak at a fitting or valve is often a repair.

Hard water and tank life in Nashville

Nashville water is moderately hard. Metro Water Services reported total hardness of 100.5 mg/L in its 2025 Consumer Confidence Report, with a range of 88.5 to 128.4. ConsumerAffairs says mineral scale from Nashville's water can shorten a tank's life to 8 to 12 years. A yearly flush ($75 to $250 nationally, per HomeGuide) clears some of that sediment; a tank that rumbles or pops when heating usually has a layer of scale on the bottom.

Permits and certificates for a Nashville water heater

Water heater work falls under Metro Nashville's plumbing and gas trade permits, and only licensed contractors with a Metro e-permit account can apply for those online. The Metro pages we read do not say whether a like-for-like swap needs a permit, so ask the plumber and get the answer in writing. Plumbing and gas inspections: 615-862-6570. Plumbers and gas fitters hold Metro certificates from the Mechanical, Plumbing and Electrical Examiners and Appeals Board; call Metro Codes at 615-862-6500 to confirm one.
