water heater hissing

Why is your water heater hissing?

water heater hissing sound can be quite concerning. It’s natural to wonder what could be causing this noise and if there is a problem with your water heater.

In this article, we will explore:

  • the possible causes of a hissing water heater
  • how to fix it
  • when it’s necessary to call a professional.

Why is my water heater hissing?

There are several reasons why your water heater is making a hissing noise.

One common cause is a leak in the water heater. When there is a leak, the water escaping through the opening can create a hissing sound.

Another possible cause is sediment buildup in the tank. Sediment can accumulate over time and minerals in the water, causing the water to make noise as it heats up. 

Lastly, a high water temperature can also lead to a hissing sound.

When the water temperature is too high, the pressure inside the tank increases, resulting in a hissing sound.

How to fix water heater hissing

If your water heater is making a hissing sound due to a leak, you should address the leak as soon as possible.

Locate the source of the leak and repair or replace the faulty valve or pipe.

If sediment buildup is the culprit, you may need to flush the water heater to remove the sediment.

Follow the manufacturer’s instructions or seek professional assistance for this task.

If the water temperature is set too high, adjust it to a lower temperature to reduce the pressure inside the tank and eliminate the hissing sound.

When should I call a professional?

While some water heater issues can be resolved with DIY solutions, there are situations where it’s best to call a professional.

If you are unsure about how to fix the hissing water heater or if the issue persists even after attempting the suggested fixes, it’s wise to seek professional assistance.

A plumbing professional has the expertise and tools to accurately diagnose the problem and provide the necessary repairs.

Causes of my water heater hissing

Are you hearing a hissing sound coming from your water heater? This could indicate a potential issue with your hot water system.

A hissing water heater can be caused by several factors, including a leak, sediment buildup, or high water temperature.

When water bubbles or condensation form inside the tank, it can create a hissing or sizzling sound.

Additionally, minerals in hard water can accumulate and cause the bottom of the water heater to make a hissing noise.

If you notice constant hissing or popping noises, or if there is water leakage around your water heater, it’s important to call a professional from Al Rooter Plumbing to:

  • assess your issue
  • resolve the problem.

Here are the causes:

Leak in the water heater

A leak in the water heater can cause a hissing sound.

The hissing noises coming from your water heater occurs when the water escapes through the opening and creates turbulence.

It’s important to identify the source of the leak and address it promptly to prevent further damage.

Sediment buildup in the tank

Sediment build up in your water heater is a common issue in water heaters, especially in areas with hard water.

As the water heats up, the sediment can create noise by moving around inside the tank.

Flushing the water heater regularly can help prevent sediment buildup and reduce the hissing sound.

High water temperature

If the water temperature is set too high, it can lead to excessive pressure inside the tank.

This increased pressure can cause the water to hiss as it boils.

Adjusting the water temperature to a safe level can resolve this issue and eliminate the hissing sound.

Is it normal for water heater hissing?

A certain level of noise is expected from a functioning water heater.

As the water heats up, you may hear some gentle hissing or sizzling sounds.

This is typically caused by the heating elements or burners as they heat the water.

These sounds are normal and indicate that your water heater is working properly.

Possible issues if the hissing sound is loud or constant

If the hissing sound from your water heater is loud or constant, it may be a sign of a problem.

It could indicate:

  • a larger leak
  • a malfunctioning valve
  • a faulty heating element. 

In these cases, it’s important to investigate further to identify the source of the issue and address it promptly.

When to seek professional assistance?

How do I prevent my water heater hissing?

To prevent your water heater from hissing, there are several steps you can take.

First, check for any leaks in the water heater tank or valves, as leaking water can cause a hissing sound.

If you’re unsure whether your water heater needs maintenance or repairs, it’s best to call a professional from Al Rooter Plumbing for assistance.

Regular maintenance to prevent sediment buildup

Regular maintenance is key to preventing sediment buildup in your water heater.

Flushing the tank annually will help remove any accumulated sediment and prevent it from causing noise and other issues.

Regularly flush your water heater to remove sediment buildup, which can lead to noise issues.

Adjust the temperature and pressure settings of your water heater to ensure they are not set too high, as this can create a hissing or sizzling sound.

Follow the manufacturer’s instructions or consult a professional for guidance.

Adjusting the water temperature

Setting the water temperature at an appropriate level can help prevent excess pressure and reduce the likelihood of a hissing water heater.

Follow the recommended temperature guidelines provided by the manufacturer.

Proper insulation and ventilation

Improper insulation and ventilation can contribute to water heater issues, including hissing sounds.

Ensure that your water heater is properly insulated to retain heat and avoid unnecessary water heater hissing noise.

Additionally, proper ventilation will help:

  • dissipate any excess heat and moisture
  • reducing the chances of hissing or other problems occurring.

Signs of a water heater leak

There are several signs that may indicate a water heater leak. These include:

  • pooling water around the unit
  • dampness or moisture
  • a decrease in hot water supply
  • rust or corrosion on the tank
  • a sudden increase in water bills.

 If you notice any of these signs, it’s important to investigate further to determine if there is a leak.
