What to do if hot water heater is knocking?

If your hot water heater is making a knocking noise, it could be the result of the expansion of mineral deposits in the tank due to the heater being old or a buildup of pressure because of a blockage in the pipes.

To determine the cause of the noise, you should first check to make sure the temperature is not set too high. If the temperature is set at the proper level, it could be a sign that the water heater has mineral build-up.

To alleviate the issue, you should drain the tank and flush it out. This can be done by turning off the power and the cold-water supply valve and attaching a garden hose to the drain valve at the bottom of the tank.

Open a nearby hot water faucet and turn the valve to the “Open” position to release the water from the tank. When the tank is empty, turn off the hose and the hot water faucet. If the noise persists, or if the tank has heavily mineralized buildup, you may need to replace the tank.

If there is a blockage in the pipes, you may need to have a plumbing technician come and inspect it. If the technician determines a clog is the cause of the noise, they can remove it and or suggest other solutions.

You may also need to check to make sure the gas pressure is not too high, which can cause your water heater to vibrate and make the knocking noise. If it’s too high, you will need to have a technician adjust the pressure.

Is a popping water heater an emergency?

A popping water heater can be an emergency, depending on the cause and severity. If the sound is coming from a bubbling sound that is often caused by trapped air in the water heater, it is usually not an emergency.

This can usually be remedied by increasing the temperature setting on the temperature/pressure relief valve. If the popping sound is accompanied by a burning smell, this can be a sign of an unsafe electrical connection or a gas leak.

If this is the case, it should be considered an emergency and addressed immediately by a professional. In any case, if the exact cause of the popping sound is not known, it is best to contact a licensed plumber for a professional assessment.
