There are a number of reasons that your water heater may be making noise.

A homeowner in Doylestown, PA, with a water heater might notice the occasional noise coming from the heater itself. Some noises are normal in the course of use, while others may indicate a problem. Here are three of the most common reasons such a heater may be making noise.

1. Sediment Collecting
It’s possible that sediment can gather in your heater and collect around the heating element. This can often result in a crackling, rumbling or popping sound. This is more likely to occur with older units but can be fixed with a water heater flush. This process involves draining the water tank and rinsing it with water until all the sediment has been removed. If you notice damage to the heater during this process, it’s best to have it repaired or replaced. Water damage from a tank leak can be handled by a water damage restoration service.

2. Valve Closed Partially
When a valve is partially closed on the water heater, you may hear a screeching sound. When the water is forced through a small opening, these sounds can occur. If the valves on the heater are fully open, you may also want to check the valves on the faucets in your home.

3. Water Heating the Pipes
Hot water travels through the pipes and causes them to expand. If the water is suddenly turned off, the pipes may shift and create a knocking or hammering sound. There are wall hammer arrestors, which are fittings that can help correct this problem when they are installed in the connection between the tank and the pipes in question.

There are a number of reasons that your water heater may be making noise. They can range from sediment in the tank to a loose heating element or just general sounds of the pipes as they expand with hot water. Most of these sounds can be managed with regular maintenance. If you do notice damage, it’s best to contact a professional.
