Clogged Discharge Pipe
A clogged discharge pipe can cause your sump pump to work harder and produce more noise. Over time, debris, dirt, and other materials can accumulate in the discharge pipe, restricting the flow of water and causing the pump to strain. As the pump works harder to push the water through the clog, it can create loud noises such as banging or grinding sounds.
To determine if the discharge pipe is clogged, you can visually inspect it for any visible blockages. Additionally, you can try using a plumber’s snake or a wire coat hanger to clear out any obstructions. If you’re unsure how to do this, it’s best to contact a professional plumber who can safely clear the pipe.
To prevent future clogs in the discharge pipe, it’s important to regularly maintain your sump pump system. This includes checking the discharge pipe for any debris or obstructions, and clearing them out if necessary.

Airlock in the System
If your sump pump is making loud and unusual noises, one possible cause could be an airlock in the system. An airlock occurs when trapped air prevents the pump from functioning properly, leading to increased noise levels.
Typically, sump pumps are designed to expel water efficiently, using gravity and pressure to move the water away from your home. However, if air gets trapped in the pump or in the discharge pipe, it can create a blockage and disrupt the normal flow of water.
When there is an airlock, the pump may strain to operate, causing loud banging, gurgling, or vibrating noises. Additionally, the pump motor may overheat due to increased resistance, leading to even more noise and potential damage.
To fix an airlock in the system, you can try a few simple steps. Start by turning off the power to the sump pump to ensure your safety. Then, locate the air vent hole on the discharge pipe, typically located near the check valve or at the top of the pipe. Using a screwdriver or similar tool, loosen the vent plug to release the air. You may hear a hissing sound as the air escapes.
Next, turn the sump pump back on and check if the noise has subsided. If the airlock was the only issue, the pump should now be able to function properly without the loud noises. If the problem persists, it may be necessary to consult a professional for further inspection and repair.
Preventing airlocks from occurring in the first place is also important. Check the discharge pipe regularly for any signs of blockage or obstructions. Make sure the pipe is properly installed and angled to ensure smooth water flow. Additionally, consider investing in a high-quality sump pump with adequate air venting features to minimize the risk of airlocks.
In conclusion, an airlock in the sump pump system can cause loud noises and disrupt the proper functioning of the pump. By following the steps mentioned above, you can troubleshoot and fix this issue, ensuring that your sump pump operates efficiently and quietly.
