When the announcement comes to each and every home, apartment, and business in the community that there will be hydrant flushing taking place, there are many that consider this a huge inconvenience. But flushing is not done for the reasons of mere folly. They are done because they are an important part of preventative maintenance.
The reason fire hydrants exist is that they are an important part of fire protection. When fire hydrants are flushed, it verifies that they are in proper working order and that they will be able to deal with the water pressure when the time comes to use them. If they are not verified, it could be disastrous to have a non-functioning hydrant being hooked up to by a fireman trying to get the job done.
Another, often unstated, purpose to hydrant flushing is that it removes mineral deposits and other sediments which can accumulate over time in the pipes which supply drinking water. By removing these deposits, the high quality of the drinking water is maintained
The process of flushing the hydrant is quite similar to draining and flushing the hot water tank which is located in most homes. When the flushing occurs, there may be a drop in water pressure and also discoloration during the time and right after the hydrant is flushed. Do not be alarmed as everything will return to normal shorty. The water pressure will re-adjust itself and the discoloration can be cleared by simply running cold water through the faucets for around three to five minutes.
The city or any community definitely appreciates all cooperation when the hydrant flushing comes time to happen. This way everything will run smoothly and there will be no confusion as to what processes are actually happening?
