How to Fix a Water Heater That Gurgles

Summary: If your water heater gurgles, there are a few things you can do to fix the problem. First, check the water pressure. If the pressure is low, it may be causing the water heater to lose heat. You can also check to see if the water heater has been properly installed. If it’s not properly installed, the water heater may not be able to get enough heat.

What Causes a Water Heater to Gurgle?

There are a few different things that can cause your water heater to start gurgling. One of the most common culprits is sediment build-up at the unit’s bottom. Over time, minerals in the water can settle at the bottom of the tank and harden. This can cause the water heater to overheat, which can lead to a gurgling sound. Another possibility is that the unit’s vent pipe is blocked. The vent pipe helps release fumes and pressure from the tank. Those fumes can build up if it’s blocked and cause the water heater to gurgle.

Additionally, the pressure relief valve may be faulty. This valve is designed to release pressure if it gets too high. If it’s not working properly, it can cause the water heater to make strange noises. The other possibility is that the water heater’s burner is dirty. Over time, the burner can become clogged with sediment and lint. This can cause the burner to work less efficiently and make noises. Lastly, the anode rod could be to blame. The anode rod helps protect the tank from corrosion. Again, if it’s not working properly, it can cause the water heater to make strange noises.

Why Is It Important to Fix a Water Heater That Gurgles?

It’s important to fix a water heater that gurgles for a few different reasons. First, if the sediment build-up is severe, it can cause the unit to overheat and eventually fail. Additionally, a blocked vent pipe can be a fire hazard. If the pressure relief valve is faulty, it can cause the water heater to explode. Another reason it’s important to fix a water heater that gurgles is that the noise can be very irritating.

If the problem is not fixed, it can cause the water heater to make noises all the time. If the burner is dirty, it can cause the unit to work less efficiently and eventually fail. Finally, if the anode rod is not working properly, it can cause the tank to corrode.

Some Easy Ways How to Fix a Water Heater That Gurgles

1. Flushing the Unit

One of the best ways to fix a gurgler water heater is to flush the unit. This will remove any sediment build-up at the bottom of the tank. To do this, first, turn off the power to the unit. Next, attach a hose to the drain valve and open it up. Let the water run out until it’s clear. Once the water is clear, close the drain valve and turn the power back on. Next, try running the hot water to see if the gurgling has stopped. If not, move on to the next tip.

2. Cleaning the Vent Pipe

If the vent pipe is blocked, it can cause the water heater to gurgle. This is because the pressure from the tank cannot escape and instead builds up and makes noise. First, turn off the power to the water heater to clean the vent pipe. Next, locate the vent pipe and disconnect it from the water heater. Finally, use a brush or other object to clear any debris that may be blocking the pipe.

Once the pipe is clear, reconnect it to the water heater and turn the power back on. If the vent pipe is clear and the water heater is still gurgling, it may be because the water pressure is too high. In this case, you will need to adjust the pressure regulator.

3. Adjusting the Pressure Regulator

If the water pressure is too high, it can cause the water heater to gurgle. This is because the water is forced through the pipes too quickly and causes turbulence. To fix this, check the pressure gauge on the water heater to see if the pressure is above 60 psi. If it is, you’ll need to adjust the pressure regulator.

To do this, locate the pressure regulator (it will be a knob or a screw) and turn it clockwise to reduce the pressure. Once the pressure has been reduced, the gurgling should stop. Avoid adjusting the pressure too much, as this can cause the water heater to fail.

4. Replacing the Pressure Relief Valve

If the pressure relief valve is the problem, you’ll need to replace it. This is because the pressure relief valve is a safety feature; if it’s not working properly, it could be a danger to you and your family. First, to replace the pressure relief valve, shut off the power to the water heater.

Next, drain the water from the tank by opening the drain valve at the bottom of the unit. Once the water has drained, remove the old pressure relief valve and install the new one. Finally, turn the power back on and refill the tank with water. Avoid overfilling the tank, as this could cause the pressure relief valve to trigger.

5. Adjusting the Temperature

If the water heater is set too high, it can cause the water to gurgle. This is because the water expands as it heats up and causes turbulence. To fix this, ensure the water heater’s thermostat is set to the correct temperature. If it is, then you can try turning it down a few degrees to see if that stops the gurgling. If not, then you may need to have a plumber look at the water heater to see if there is a problem with the thermostat.

6. Checking the Tpr Valve 

The TPR valve is a safety feature that prevents the water heater from exploding. If the TPR valve is not working properly, it can cause the water heater to gurgle. To check the TPR valve, first, turn off the power to the water heater. Then, remove the TPR valve from the water heater. Inspect the TPR valve for any debris or damage. If the TPR valve is damaged, it will need to be replaced. If the TPR valve is not damaged, clean it with a brush and reattach it to the water heater.

7. Reducing Hard Water 

Hard water can cause a water heater to gurgle. This is because the minerals in hard water can build up on the heating elements, causing the water to heat unevenly. This can cause the water to gurgle as it is heated. There are a few ways to reduce hard water. One is to install a water softener to remove the minerals from the water.

Another is to use a descaling solution, which will break down the minerals so they can be flushed from the system. If you have hard water, you may need to descale your water heater once a year to prevent gurgling.

8. Tightening Connections 

If the water heater is gurgling because of loose connections, you’ll need to tighten them. First, turn off the power to the water heater. Then, locate the loose connections and tighten them with a wrench. Once the connections are tight, turn the power back on and test the water heater to see if the gurgling has stopped. If the water heater is still gurgling after tightening the connections, there is likely a problem with the water heater itself and you’ll need to call a plumber.

9. Hire a Professional

If you’ve tried all of the above solutions and the water heater is still gurgling, it’s time to call a professional. A plumber will be able to diagnose the problem and make the necessary repairs. Water heaters are a vital part of any home and should be treated as such. If your water heater is gurgling, don’t ignore it. Try one of the above solutions to see if you can fix the problem yourself. If not, be sure to call a professional.
