What To Do If Your Water Heater Is Making Noises

3/12/2023 (Permalink)

A water heater is an important appliance that provides hot water for a variety of household needs, including washing dishes, doing laundry, and taking showers. However, if you start hearing strange noises coming from your water heater, it can be cause for concern. In this blog post, we will discuss what to do when your water heater is making noises.

Step 1: Determine the Type of Noise

The first step in addressing a noisy water heater is to determine the type of noise you are hearing. Is it a rumbling or popping sound? Is it a hissing or whistling sound? The type of noise can help identify the source of the problem.

Rumbling or popping sounds are often caused by sediment buildup in the tank. This can lead to overheating and damage to the tank if left unchecked. Hissing or whistling sounds, on the other hand, may indicate a leak in the tank or a malfunctioning pressure relief valve.

Step 2: Turn Off the Water Heater

Once you have identified the type of noise, the next step is to turn off the water heater. This will prevent any further damage from occurring and ensure your safety while you investigate the problem.

Step 3: Inspect the Tank

Carefully inspect the tank for any signs of damage or leaks. If you notice any cracks or leaks, you will need to call a professional plumber to repair or replace the water heater.

If you don't see any visible signs of damage, you may need to flush the tank to remove sediment buildup. To do this, turn off the water supply to the tank and attach a hose to the drain valve at the bottom of the tank. Open the valve and let the water drain out until it runs clear.

Step 4: Check the Pressure Relief Valve

If the noise is caused by a malfunctioning pressure relief valve, you will need to check the valve and replace it if necessary. To do this, turn off the power and water supply to the tank and remove the valve. Inspect it for any signs of damage or debris, and replace it if necessary.

Step 5: Call a Professional

If you are unsure about what is causing the noise or if you are uncomfortable performing any of the above steps, it is best to call a professional plumber. They can diagnose the problem and recommend the best course of action to repair or replace the water heater.

In conclusion, if your water heater is making noises, it is important to act quickly to prevent any further damage and ensure your safety. Determine the type of noise, turn off the water heater, inspect the tank, check the pressure relief valve, and call a professional if necessary. By following these steps, you can keep your water heater running smoothly and avoid any costly repairs or replacements.
