You are hearing a lot of noises from hot water heater that has served your family loyally for the past four years. What do you think is wrong?
Here’s a list of common noises from hot water heater and their usual causes. One of these things could be wrong.

Popping, Banging, Crackling, Gurgling, Ringing, Rapid Surging Boiling Water, Rumbling
If you hear loud popping, cracking, or clanking noises from your hot water heater while operating it, it’s probably because mineral deposits have accumulated on the bottom of the water heater tank’s interior surface.

Hissing Noises
If your water heater is an electric unit, mineral deposits can cause a hissing noise when the heating electrodes are operating.

Humming
The element in an electric water heater is commonly placed vertical in relation to the tank. Water flowing around the element can cause vibrations in this situation, creating a humming noise. Tighten the element slightly to correct the problem.

Knocking or Hammering
A knocking sound in your walls is related to pipes heating internally, and is literally known as "water hammering." When water entering or leaving a tank is abruptly turned off, it can cause the pipes to shift, bang against studs or the interior of walls. This can be caused by a dishwasher or toilet bowl, or by a water pump without a holding tank. The noise is not dangerous to your water heater, but could lead to eventual wall damage if it is not corrected. Install a "water hammer arrestor" between the offending device and the water heater so you can prevent the noises from hot water heater.

Tank-less Water Heater Noise
Tank-less water heaters have their own distinct noises. If you hear a clicking noise, this is typically just the flow switch turning on and off to start and stop the flow of water and is completely normal. If it’s making a lot of noise when turned on, it may be because calcium deposits are being left behind due to hard water in your area. Installing a water softener system may be necessary. Others reasons for a noisy tank-less water heater model may be an issue with the burner, the fan may be dirty, or possibly a leak in the sealed combustion resulting in irregular gas combustion

Hot water tank experts recommend replacing your water heater if it is older than 15 years. And they are right to do so as an old water heater can cause a variety of water heater issues and pose a threat to your safety and health if not replaced in time. Here are 3 signs that your water heater is dying and the problems it can cause.

1) Rumbling noise

If you hear a rumbling noise each time your water heater is in use, it is one of the key signs that your water heater is dying. Rumbling noise from the water heater indicated the build-up of sediment inside the water tank. This sediment can obstruct the water from getting heated and interfere with the heating efficiency of the water heater. Sediment build-up also reduces the energy efficiency of the water heater as the heater consumes excess energy to achieve the same level of heating. Flush your hot water tank with water once in every 3 months to get rid of sediment formation. If the problem persists, consult your local hot water tank experts and get your old water heater replaced.

2) Water leakage

Water leakage is one of the most troublesome water heater issues. This could be caused due to corrosion or rust forming inside the hot water tank and is irreparable. If not addressed immediately, a rusted water heater could give out rusty water with a metallic taste and smell and could be a dangerous health hazard. Water leakage could also contribute to an increase in your water and energy bills. Replace a leaky water tank at the earliest to save money and safeguard your health and safety.

3) Faulty Pressure Relief Valve

The pressure relief valve is responsible for releasing the excess heat and pressure generated during the water heating process and protecting the water heater from exploding. If your pressure relief valve is not functioning correctly, it will be unable to release the excess pressure due to overheating and your water heater could explode with the pressure of a small bomb. This is a serious risk to safety and a life-threatening problem. Check if your pressure relief valve is functioning properly by snapping it open and observing the water release from the valve. If this does not happen, you need to replace the valve. Sometimes, the pressure relief valve may develop a leak. Do not cap off the valve to fix the leak as this hinders the ability of the valve to release pressure. Instead, ask your local hot water tank experts to replace the valve and ensure your safety. If despite regular replacement of the valve, your water heater continues to overheat, it could be one of the major signs that your water heater is dying.

Watch out for such signs that suggest your water heater is dying and replace it before it can cause damage to your health and pose a risk to your safety. Get in touch with reliable hot water tank experts for the timely replacement and maintenance of your old water heater.
