Experiencing discolored water? This does not automatically mean water quality issues but could be the result of several factors. Two of the main sources are utility main disturbances and internal plumbing.
When there is a water main break, system improvements and water main flushing activities, it is not uncommon for customers to see discolored water. A change in water pressure within the distribution system, often resulting from water main breaks, is also a common reason you may have discolored water. Sediments in pipes, trapped air in the system and natural minerals can lead to discoloration as well.
Brown, red or yellow colored water usually contains an excess of iron/rust or manganese. If the discoloration appears across cold water faucets, a utility disturbance is likely the source. However, if it is isolated to hot water then the issue may be the water heater itself. Sediment and minerals build up at the bottom of the tank over time, which is why routine flushing is important.
Green water is a sign that algae are present in the source water; river, lake or reservoirs that supply your water.
Blue water can occur if you use blue disinfectant in your toilet and your water supply was recently turned off. This could create a condition where water from the toilet tank is siphoned into the plumbing of your house.
Cloudy or white water is typically caused by trapped air, which is likely in cold water and can also come from construction and maintenance activities.
Most discolored water is safe to use for bathing and cleaning, but it may stain clothes or fixtures. Running the cold tap for several minutes can often flush out sediment. If discoloration continues, it is best to contact Richmond DPU at 804-646-4646 or you may also need to contact a plumber if it is related to home plumbing.
Customer Tips for After a Water Main Repair
Still Seeing Discolored Water? Here’s What to Do...
1. Check Your Water
- Test your cold water once every 30 minutes by running one faucet for 1-2 minutes.
- If it’s still discolored, turn it off and check again in a half hour.
- In most cases, brown water clears within a few hours.
2. While You Wait
- Don’t let your water run continuously after the 2-minute test; it won’t clear faster.
- Avoid using hot water to keep sediment out of your water heater.
- Hold off on washing light-colored laundry to avoid discoloration of clothing.
3. Once the Water Runs Clear
- Run all cold-water faucets for 1-2 minutes to flush your home’s plumbing.
- Clean faucet aerators if they’re clogged with sediment.
- If toilet water stays discolored, don’t worry; it may take longer to clear.
- If only your hot water is discolored, wait for sediment to settle, run hot water briefly or have your water heater flushed if needed.
