There are a few reasons why your tap water may appear white or “milky” when it comes out of your tap. The typical reason may be from the water district having to perform planned or emergency maintenance on the distribution system main water lines or your service line. If this is the case, the district is already or would be happy to come out and continue to flush the main lines in an effort to help remove the air from the area. Another reason is cold weather. Cold water holds dissolved air, so during colder months, you may see more air than normal when the colder water from the distribution system enters the warmer pipes of your home. This will cause the dissolved air to release, therefore causing the white color in the water. If you feel you are experiencing either of these two reasons for “milky” water, just give the district a call and explain. (270)259-2917 Another possible reason is from any recent plumbing repairs or installation that has been done in your home. Air can get trapped in plumbing and during larger flow can get released. If you have recently done some plumbing maintenance in your home, you can resolve the air by just letting your faucets run for a few minutes at full flow to clear up the air. If you feel the issue is larger than what is in your home plumbing, you may need to call the water district and report that you are seeing air in your water. The district would be happy to come investigate and see if the issue is happening in the distribution system and if so, the district will flush the water main to remove the air. If the cloudiness is just air, there isn’t any reason to be concerned of the safety of the water. It’s safe to drink just a little unpleasant in appearance. All of the above reasons for a “milky” appearance are most likely only seen on the cold side of your plumbing. A way to test if air is the cause of cloudiness in your water is to fill a clear glass full and let it set for a few minutes. If the water clears up in the glass after a few minutes, then it is air you are experiencing.
If you see a very white cloudy water that doesn’t appear like air coming from your hot water, this could be a little bigger concern and mean that your water heater has some calcium buildup from the change in Ph that happens when you heat the water in the water heater. To help prevent this you should always follow the water heater manufacturers recommendation on draining and cleaning your water heater. This is typically suggested to be done yearly. You may also need to replace the sacrificial rod in your water heater tank. If you need help with either of these, you should call a licensed plumber for help.
