Why Does My Water Heater Make A Knockin Sound?

When it comes to why does my water heater make a knocking sound, one of the major reasons why you will hear this sound is because of poor maintenance. If you want to avoid the sounds of water freezing and thawing in your home, you will need to take some action when it comes to checking on your water heater periodically. The easiest way to go about doing this is to have a professional unit serviced once per year. Most of the time, you will hear this knocking sound if you are trying to turn the water off or if the unit is trying to hold the temperature after the water heater has stopped. In order to stop the sounds of water thawing or turning, you will need to add the correct liquid detergent into your water tank or you can also have your unit serviced and checked by a professional once every six months.
