Hydrant and Water Heater Flushing
Twice a year (spring and fall), the City of Fridley flushes out its water mains through the fire hydrants. The purpose of flushing the water lines is to clear the water mains of small amounts of sediment like iron or manganese that settles in water mains over time. We also verify that the hydrants are in good working order.
After flushing of the City's mains is completed, we suggest that you flush your hot water heater, which can accumulate sediment over time.
During flushing, deposits from water lines may create a yellowish to brownish discoloration of water in homes near flushing areas. While this water is safe for drinking, it may discolor laundry. If this discoloration last longer than two days, residents are asked to call the City's Public Works Department at (763) 572-3566. Resident may also call Public Works to get current flushing locations and updated information.
Water Heat Flushing
Each year after the spring water main flushing program has been completed, we suggest residents flush their hot water heaters. Many types of sediment such as iron, magnesium and calcium may build up in the bottom of your hot water heater, causing discoloration or rust in the hot water taps. (Calcium appears as sand particles in the hot water system.) In most cases, flushing the hot water heaters can eliminate this. Listed below is a simple procedure you can follow to flush your hot water heater:
