Is your water heater making a knocking noise that’s driving you crazy? This common issue can disrupt your daily routine and indicate underlying problems with your water heater. Addressing it promptly is essential to avoid costly repairs, improve efficiency, and maintain peace of mind.
A knocking sound usually signals sediment buildup, high water pressure, or loose connections. Ignoring these signs can lead to inefficient heating, higher energy bills, and potential damage to your system. While DIY solutions might seem tempting, some fixes require the expertise of a professional plumber to ensure safety and long-term results.

Causes of Water Heater Knocking Noises
Sediment Buildup
One of the most common reasons for a water heater making a knocking noise is sediment buildup in the tank. Over time, minerals like calcium and magnesium from hard water accumulate at the bottom of the tank. When the burner heats the water, the trapped sediment creates pockets of steam that cause the knocking sound.
This buildup not only creates noise but also reduces the efficiency of your water heater. The system has to work harder to heat water, leading to higher energy bills and potential damage to the tank. Regular maintenance, such as flushing the tank, can prevent sediment from becoming a problem.
High Water Pressure
High water pressure can also cause a noisy water heater. When the water pressure in your system is too high, it forces water to flow rapidly, creating vibrations and noise. This pressure can stress your plumbing system, increasing the risk of leaks or bursts.
Installing a pressure-reducing valve and regularly checking the pressure can help maintain safe levels and prevent unnecessary noise.
Pipe Expansion or Loose Connections
Knocking sounds may also result from pipe expansion or loose connections. As hot water flows through the pipes, they expand and contract, which can cause them to knock against walls or other surfaces. Loose fittings or connections exacerbate this issue, leading to persistent noise.
A professional plumber can inspect your system and secure or replace loose components to eliminate this problem.
Fixing a Noisy Water Heater
Flushing the Tank
Flushing your water heater tank is a straightforward way to remove sediment buildup and stop the knocking noise. Here’s how it’s done:
- Turn off the water heater and allow it to cool.
- Connect a garden hose to the drain valve and direct the other end to a safe drainage area.
- Open the valve and let the water flow out, flushing away accumulated sediment.
Regularly flushing your tank (once or twice a year) can improve your water heater’s efficiency and extend its lifespan. If you’re not comfortable performing this task, Beeline Plumbing can handle it for you professionally and safely.
Adjusting Water Pressure
To fix knocking noises caused by high water pressure, start by checking the pressure level using a water pressure gauge. Ideally, your home’s water pressure should be between 40-60 psi. If it’s higher, install a pressure-reducing valve to maintain safe levels.
Excessive water pressure isn’t just noisy; it can damage your plumbing system over time. A professional plumber can ensure the correct installation and adjustment of the valve for long-term performance.
Inspecting Pipes
Loose or poorly secured pipes often contribute to water heater knocking sounds. A thorough inspection can identify areas where pipes may be rubbing against surfaces or where fittings need tightening. Adding pipe insulation or cushioning can further reduce noise and prevent wear and tear on your system.
Why You Should Address Water Heater Noises
Preventing Damage
Ignoring a noisy water heater can lead to significant damage. Sediment buildup, for example, can corrode the tank, reducing its lifespan and potentially causing leaks. High water pressure may strain your plumbing system, resulting in costly repairs.
Addressing these issues early can save you money and prevent inconvenient breakdowns. Regular maintenance and timely repairs are essential for a reliable water heater.
Saving Energy Costs
A noisy water heater often works harder to heat water, consuming more energy. This inefficiency translates into higher utility bills. Flushing the tank and ensuring proper pressure levels can restore efficiency, helping you save money in the long run.
