Any electric item which is making a weird noise can be alarming and there are two major reasons behind the noise, either that unit needs to be changed or needs high-grade maintenance. The same is with the sump pump, although when the sump pump makes continuous low noise when it is working, loud noise can be an indication of something wrong, so the question arises of how to stop the sump pump banging noise.
Don’t fret as the solution is pretty simple and easy to apply but for that, you have to spare only 5 minutes and tag along as I will cover the major issues that let the sump pump make banging noise and will also cover how can you recognize the problem along with the troubleshooting. Let’s get started then.
How To Stop Sump Pump Banging Noise
There are different types of sump pump noises. Similarly, there could be plenty of reasons behind the sump pump making banging noises and to stop these irritating noises one should first diagnose where this is coming from. Although every sump pump makes some noise, you should start to worry when this noise becomes irritatingly loud and constant.
- There is an 80 percent chance that the noise might be coming from the discharged pipes which start to vibrate when the heavy flow of water takes place.
- The second reason might be the poorly maintained unit and some of its screws need to be tightened.
- The third and the most common mistake due to which we hear our sump pump making creepy noises is that it is installed out of the pit.
Apart from these reasons, there could be other reasons as well, but these three are the common reasons. So as you now know that there might be various reasons behind this banging noise, instead of making up your mind that your sump pump is broken out and needs to be replaced with the new one it’s better to detect where the fault lies.
Now the first thing you are supposed to do is find out which part of the sump pump is creating this noise and why. After that resolve, that issue by yourself only if you know the basic plumbing, and if you have no idea then not a big deal, just call out any professional and ask him to troubleshoot the banging noise.
One thing to do before you start to diagnose where the problem lies is you should switch off the sump pump. Otherwise, it could be fatal. Moreover, don’t forget to plug in after troubleshooting these problems as leaving the sump pump unplugged can let your basement face flooding.
Now let’s jump into the solution of these basic issues which might be the cause of the sump pump making banging noises. I will explain the solution to each problem one by one. First of all, make sure that the sump pump is not on the ground level of your basement but inside the pit. Actually, the pit consumes a lot of the noises generated by the sump pump and the pit is the right place for the sump pump in every way it is not supposed to be out of the pit.
Secondly, check that the discharge pipes are secured properly and are not loose, otherwise when the water will travel through them the flow of water will make the pipes rattle which will make weird sounds. Now the third case could be that the unit as a whole is not installed properly or some screws are loosened up and need to be tightened properly.
