- Sump pump noise problems
How Do Silent Check Valves Work? As mentioned, the common cause of banging noises from a sump pump is the sudden change in pressure when the pump turns off. This is such a common problem that someone invented silent check valves. While designs will vary between manufacturers, they'll all follow the same basic idea. Many have spring-loaded valves or flappers, which make the valve's closing a bit smoother. Think of soft-close toilet seats and you're not far off. This simple yet effective change is enough to reduce banging noises because it basically dampens the closing mechanism and means there's not such a sudden shift in pressure. You might still notice a very minor noise while the valve shuts, but it'll probably be more of a sucking noise than a banging noise. Either way it's a vast improvement on those loud banging noises you usually hear. Some Final Thoughts
Fixing sump pump banging noises is generally pretty easy. Providing you've got the tools to replace the check valve, it shouldn't take you longer than 20 minutes.
Sump pump noise problems
The bigger the motor – and more horsepower – the louder the pump! If you have a deep basement and need a pump with a lot of power to lift water you might be stuck with a high power pump if you want to avoid a flood! Every pump is going to make some amount of noise – the important thing is determine what you consider to be an "acceptable" level of noise! It is important to keep in mind that if you live in an are with a lot of ground water or a deep basement you will likely need a powerful pump and need to use a sound proof cover to block the noise. Find one that is a tight fit on your sump pit with a little ventilation for best results.
If your home or driveway sits on low land, your basement is at risk for flooding when rain levels are high. Sump pumps remove excess water from a sump basin and carry it through a series of pipes away from the house. Sump pumps are a relatively inexpensive means of protecting your basement from seasonal flooding, but improperly installed or older pumps can create quite a racket. Identifying the exact source of the noise helps you determine whether a simple repair or a complete replacement is in order. Vibration or Clanging Identify the pump's discharge pipe. When water flows through the discharge pipe, the pipe may vibrate against the pump basin or the surrounding wall. Wrap the discharge pipe in foam insulation to prevent the pipe from banging against the wall. Insulate the joint where the discharge pipe meets the flooring. If the pipe has direct contact with the flooring, the pipe vibrations can be loud. Surround the pipe and flooring with foam insulation or noise dampening material.

You might consider wrapping the piping with insulation to dampen the sump pump clang. You might also silence a banging, clanging sump pump lid by adding rubber grommets underneath. Sometimes, the only way to silence the pump is to correct the discharge pipe position. During installation, your earlier plumber may have used too many 90-degree angles, impeding the function of the sump pump. We can retrofit and create a straighter path for the water to flow. Then your pump should be quieter and run better overall.
This means it's in direct contact with moisture, so it's more likely to wear out or rust than a pedestal pump. But it is the quieter option and the most commonly used type. Why Is My Sump Pump Making a Noise? Without audio samples, noises can be difficult to diagnose. But we're going to do our best! Is it a "thunk" that you're hearing? Does it occur whenever the sump pump turns on or off? It may sound like someone is hitting a pipe with a hammer. This noise is loud enough to startle you, especially at night when your home is quiet. This most likely stems from the check valve on the sump pump. The check valve opens when water runs past it and closes when the water is gone. Like a door, this opening and closing can make noises. An easy way to reduce or eliminate this thunk is to replace the valve with a "silent check valve" available at home improvement stores. Do you hear a loud rumbling motor sound? This usually sounds similar to a car engine idling roughly. These noises are most common in older sump pumps.
A small repair could extend the life of your pump, but if it is making a lot of noise, you may find that it is best to replace your current sump pump with up to date unit. Newer sump pumps take advantage of updated technology plus they can link with your WIFI to send automated alarms and alerts. Too small of a pump can spell trouble. Constant noises can mean that your pump is simply too underpowered to deal with the moisture in your basement. An underpowered pump is going to burn out. Unfortunately, this is most likely to occur when you need it the most. It is best to replace the underpowered pump before it gives out. If your sump pump is loud, then this is often incentive enough for repairs or replacement. A sump pump motor and lines need proper lubrication to work properly. Noises can mean that your motor hasn't been lubed in awhile. Lack of lubrication can lead to your sump pump having parts that wear out faster due to grinding together. PVC pipes and lines make more noise than cast iron, so if you have plastic, it is wise to consider an upgrade.
The prudent practice is to address these noises as individual issues. Rather than taking the "collective" measure to quiet the pump – it'll mean nothing. Once you have identified that the discharge pipe is the culprit for banging, for instance, quick intervention in the form of insulating it with a suitable foam may be enough. But, definitely, not the solution for the clanking and slurping noises. 3. Locate the Check Valve on Your Discharge Line
When you hear the sump pump making a loud noise like gurgling or slurping, it's high time to check the standard swing valves and replace them if they are having operational issues. The check valves should be unbroken and fitted correctly. Otherwise, problems will arise. The valve fails to work normally because there's a whole junk of debris buried in it. This makes it become noisy automatically. This noise means that there's poor control of water flow for discharge in pipes. So the water keeps flowing back down the pipe instead of having a steady, more controlled flow.
Step 2: Locate the Check Valve and Measure the Drainage Pipe
The drainage pipe runs from the sump pump to outside the home to carry water away from the house. You can find the check valve on this pipe, typically about two feet from the pump. Check the diameter of the drainage pipe. PVC pipe typically has the diameter printed on it. If not, remove the old check valve and measure across the pipe's open end with a tape measure. (See the next step for how to remove the old check valve). It's essential to get the right measurement; if you can't, cut a small section of the pipe (not too much). Bring this piece with you to the store when you buy your replacement parts. You need to ensure you get the right fittings to install your new check valve into the existing drainage pipe. Step 3: Remove the Old Check Valve
If metal clamps are holding the check valve in place, turn the screws counterclockwise. Once you loosen the valve, disconnect the lower pipe. Hold the bucket underneath it to catch any water that is still inside the pipe.
Since you purchased your sump pump, you probably are enjoying the dividends. Come rain or sunshine, this little machine is a savior. Sump pumps are handy in a basement drainage system.
