WARNER ROBINS -- Firefighters are expected to start annual hydrant testing across the city March 11.

The testing may cause the stirring of sediment in water lines, so residents are advised to let water run for several minutes if this happens, a Warner Robins Fire Department news release stated.

Residents should wait several hours after testing in their neighborhood before doing laundry to keep their clothing from getting stained.

Anyone with questions may contact the fire department at (478) 293-1020.
