Although the immediate outages were fixed Sunday morning, Jordan said the situation created the potential for more problems in the future.
Opening up fire hydrants has a significant effect on the water pressure and flow running through pipes. That takes its toll on the system's water lines, some of which are up to 50 years old.
"Any time there's a huge change in the amount of pressure going through the system, it can definitely cause some damage to the pipes underground," Jordan said.
She said even when trained firefighters open hydrants properly, they run the risk of damaging underground pipes.
"There's a possibility there could be more water main breaks in that area due to this tampering," she said.
Jordan said anyone with information that could lead to the arrest or conviction of those involved should call the Putnam County Sheriff's Department at 304-586-0256.
Jordan also said anyone who spots a person tampering with a hydrant should call the company's customer service center at 800-685-8660.
"We hope that the announcement will let people know that tampering with a fire hydrant is not a minor incident, because it's truly not," she said.
