NASHVILLE, Tenn. -- The Channel 4 I-Team found hundreds of fire hydrants all over Davidson County that experts say may not have enough water flow to put out a fire.

Now, a home has burned with a low-flow hydrant in front of it, and that prompted a meeting among neighbors and the city's fire chief.

The fire department said it has a solution, but the community's vice mayor has his doubts.

Fire trucks lined up one after the another, forming a relay of water up the hill on Villa Crest Drive.

The fire hydrant closest to the burning home was a low-flow hydrant and wasn't putting out enough water to tackle the flames, so 2,400 feet of hose were strung from one fire truck to the next.

"I'm concerned that all of our residents have adequate water protection, and having a low-flow hydrant certainly presents a concern," said Austin McMullen, Oak Hill vice mayor.

Three months ago, a Channel 4 I-Team investigation found 586 hydrants across Davidson County that don't meet national or international standards for minimum water flow.

Fire protection experts said then that if a full-blown fire broke out in front of one of these hydrants, the house would likely burn to the ground.

In the case of the Villa Crest home, that's exactly what happened.

Daniel Hill lives in a wood home directly across the road from the low-flow hydrant on Villa Crest Drive.

"I do have concerns," said Hill. "We're definitely going to keep the pressure on them, you know, to solve the problem."

Neighbor Tim Villager sent a letter to the fire chief, the water department and city leaders, writing the hydrant situation is "frightening," that firefighters did a "truly great job" and that if Nashville had given them the supply they needed, the owners would have a lot "more to salvage."

"(There is) very much concern on the street about that hydrant," said Villager.

Villager said he was surprised by how quickly the city's fire chief responded, organizing a meeting and laying out how they'll now do relay drills in the area to practice bringing water up the hills.

"It's gonna take some additional equipment. It's a little more complex procedure as far as a relay where you use, in this case, four of five fire engines," said Nashville Fire Department Chief Jerry Smith.

But McMullen questions if the relay is just a temporary fix.

On the night of the fire, it took 20 minutes for the relay to get all the water needed on the flames.

"My concern is the time that it would take to set up the relay and that there be enough water in order to save lives, save property and save neighboring properties," said McMullen.

The fact that the I-Team found nearly 600 low-flow hydrants across Davidson County -- seven in the Oak Hills ZIP code -- points to the problem of the city's aging water system.

There's enough water for everyday use, but the low-flow hydrants don't have enough water for full-blown firefighting flow.

The city's water department estimates it would cost millions to replace the pipes and the low-flow hydrants.

All firefighters can do is know where the low-flow hydrants are and plan for the worst.

"They're familiar with where the lower-flow hydrants are. It does catch your attention more so than one that's got more water in it," said Smith.

Smith said the key to working around the low-flow hydrant problem is early notification of fires. If they can get to a fire quick enough before it becomes like the one on Villa Crest, then he feels they can save houses.
