MVD performs routine valve exercising on the water main valves to ensure the valves located throughout the water distribution system are in working order and able to be operated as necessary. Each valve is operated through a full cycle of shut-off and turn-on, then returned to its normal position; this helps prevent buildup of sediment in the pipes that could render the valve inoperable or prevent a tight shutoff. 

Please note: During the valve exercising, there can be fluctuations of pressure and/or brief interruptions of water service. Additionally, valve exercising may cause discolored water.

Discolored water is typically caused by sediment, such as iron. Although discolored water is not aesthetically pleasing, it is not unsafe** and can be easily resolved by flushing the water service line to the property. Flushing allows a larger than normal quantity of water to flow through the service line, which helps clear out the sediment. You may notice the discoloration return after the water has sat in the lines for a period of time, such as overnight or during the day if it’s not being used – this is to be expected. When the water is not used for a longer period of time, the sediment settles; when water is turned on it is agitated and the discoloration returns. If this happens, you may repeat the flushing process. 

If your water is discolored, we recommend avoiding the use of hot water until the cold water is clear. If you have used hot water before/during flushing and are noticing discoloration in the hot water, the water heater may need to be flushed – refer to the manufacturer’s manual for instructions or contact a licensed plumber.

**Some people may be more vulnerable to contaminants in drinking water than the general population. These individuals should consult with and seek advice from their health care providers.
