Sump Pump Banging Noise: Causes, Effects, and Solutions
In order to keep basements dry and avoid costly repairs, sump pumps are a must-have. These pumps drain water from a basin on the basement’s lowest level, called a sump. Nevertheless, these pumps can generate a loud banging noise that is both annoying and potentially dangerous. This article will define the problem of a noisy sump pump, discuss its sources and consequences, and offer advice on how to eliminate the commotion.
What is a sump pump banging noise?
A sump pump banging noise is a loud noise that occurs when the sump pump turns on or off. The noise can be described as a loud thud, bang, or clunking sound. The noise is usually caused by the pump’s check valve slamming shut after the pump turns off. The check valve is designed to prevent water from flowing back into the sump basin, but when it closes too quickly, it can cause a banging noise.
The causes of the sump pump banging noise
There are various causes of hammering sounds coming from sump pumps. The most frequent causes are:
- Airlocks: On occasion, air may become entrapped in the discharge line of the sump pump, leading to an airlock. The trapped air may build pressure when the pump is turned off, causing the check valve to slam shut and generate a pounding sound.
- Clogged discharge pipe: If the pump has to work harder than usual to clear the obstruction, the check valve may slam shut.
- Damaged check valve: The check valve may eventually grow worn out or damaged, which will cause it to close too quickly and generate a pounding noise.
- Loose pipes: Pipes that are loose might cause the pump to vibrate and make a hammering noise.
Effects of sump pump banging noise
Sump pump Banging noise can have several negative effects, including:
- Damage to the pump: If the banging noise is caused by a damaged check valve or loose pipes, it can cause damage to the pump over time.
- Disruption of daily life: The loud banging noise can be disruptive and make it difficult to sleep or concentrate.
How to stop sump pump banging noise: 7 ways
There are several ways to fix sump pump banging noises. If you have a sump pump installed in your crawl space or basement, you are aware of the loud banging noise it can create. The check valve that is installed in the sump pump discharge pipe is typically to blame for this noise. We’ll talk about some of the best strategies for reducing sump pump banging noise, including:
- Inspection and maintenance: Regular inspection and maintenance can prevent the sump pump banging noise from occurring. This includes checking the discharge pipe for clogs, tightening loose pipes, and replacing worn-out parts.
- Replace the Check Valve: Water cannot flow back into the sump pump due to the check valve in the discharge line of the sump pump. The valve may malfunction and make a pounding sound as a result of wear and tear over time. The valve needs to be changed out for a new one as a remedy. Make sure the new check valve you install is high-quality and the appropriate size for your sump pump.
- Use a Silent Check Valve: Consider installing a silent check valve if the banging noise still exists after replacing the check valve. These valves are made to lessen the noise that the sump pump makes as water flows back into it. Quiet check valves eliminate the slamming sound by using a spring-loaded mechanism to slowly close the valve.
- Install a Water Hammer Arrestor: Another way to stop the sump pump banging noise is to install a water hammer arrestor. This device is installed in the water supply line and acts as a shock absorber, preventing the water from slamming against the pipes and creating a banging noise. Water hammer arrestors are available in different sizes and can be installed by a professional plumber.
- Secure the Pipes: Loose pipes can also cause banging noises when the sump pump is running. The movement of the water through the pipes can cause the pipes to vibrate and hit the walls or other objects, creating a loud banging noise. To fix this problem, secure the pipes to the walls or ceiling using pipe clamps or straps. This will prevent the pipes from moving and eliminate the banging noise.
- Insulating Pipes: Insulating your pipes is an excellent way to decrease the noise generated by your sump pump. The insulation has the capacity to soak up the sound and obstruct its transmission throughout your dwelling. Fortunately, foam pipe insulation is a straightforward and convenient option that is obtainable at numerous hardware retailers.
- Professional repair: If the banging noise persists even after inspecting and replacing damaged parts, it may be time to call a professional plumber for repair.
Soundproofing Solutions for Banging Noise
In addition to repairs, soundproofing solutions can help reduce sump pump noise and improve home comfort. Anti-vibration pads and noise barriers are two options that can reduce the noise of a sump pump significantly. Installing these solutions is easy and can be done as a DIY project.
Sump Pump Maintenance to prevent banging noise
Regular maintenance is essential to prevent sump pump banging and extend the lifespan of your pump. To maintain your sump pump, start by cleaning the pump and the sump pit regularly. This prevents debris buildup that can clog the pump and cause it to malfunction. Also, test the pump regularly by pouring water into the sump pit and ensuring that it activates and pumps the water out efficiently.
Sump pump pounding noise is a typical issue that can have a negative impact on your home and daily life, to sum it up. Yet, it is a problem that can be solved with appropriate inspection, upkeep, and repair.
