(KMOV)-- After firefighters responded Monday to a minor fire in a St. Louis neighborhood and discovered a broken hydrant, officials quickly repaired it Tuesday.
The repairs followed a News 4 investigation.
The water department says the reason the hydrant did not work is because it was vandalized and ruined when untrained personnel opened it.
Officials said this happens to many other hydrants throughout the city, and that the threads inside each hydrant, where firefighters attach hoses, can be stripped when opened or closed too quickly, causing the entire water main to break.
Last year the water department fixed about 375 hydrants, costing $500 to $2000 for each repair.
Firefighters do inspect and maintain every fire hydrant in the city, but some are opened illegally after they have already been checked by proper officials.
