City of Ann Arbor begins flushing the spring hydrant

ANN ARBOR – The city of Ann Arbor has announced that it will begin flushing the spring hydrant on April 12th.

Flushing the hydrant removes deposits and minerals that have accumulated in the water pipes. Preventive maintenance also allows the city to monitor water pressure to make sure the system is working properly.

Rinsing is done weekly from spring to autumn.

Check the hydrant flush map to see when your area is flushed.

City officials are warning that if there is a flush near you, your water could temporarily turn an orange, rusty color. This is due to the disturbance of the iron sediment in the water pipes during the hydrant flush and is not dangerous.

The water is potable and residents are asked to leave the tap closest to their water meters running in the cold until their pipes are clear. Toilets should also flush once or twice if you notice a reddish tinge in your water.

“The water should be clear within a few minutes, but it can take until the evening when the hydrant flushing stops and more people are home to clear the rusty water from the system,” the city wrote in a press release.

In contrast, residents are asked not to run hot water as soon as they notice any discoloration as it will be pushed into the water heater. If rusty water gets into your water heater, drain the device according to the manufacturer’s instructions.
