Two water main breaks are affecting Tennessee American Water customers in Lookout Valley Thursday.

The breaks happened overnight and customers in the area may have little or no water pressure.

The smaller of the two breaks is located on Ochs Highway and has been repaired, with water service being restored.

The larger break is located on Cummings Road near Wahautchie Pike. Repair work will continue all day and into the evening.

Tennessee American Water advises that customers who experience air in their pipes or discolored water after their water is restored should run their cold water until it runs clear.

A larger volume faucet, such as the ones on bathtubs, can speed the process.
