The purpose of gravel is to bring the surface back to level and remove excavated-ness because water has dynamic viscosity and it flows in all directions. Therefore, gravel works as a resistance to avoid flooding. You can spot the gravel, of course, by its appearance—but there is a case in which gravel is invisible apparently.

The visibility of gravel will clear your uncertainty.

There are some primary reasons behind “why is there gravel in sump pit”: First, the gravel resists the kids or pets from falling into the pit or water area. Secondly, it improves the overall flow of water and reduces debris accumulation. Over that, the gravel indirectly protects the sump pump machine and makes it last longer than usual.


Should there be gravel in the sump pit?

Yes! The addition of gravel in the sump pump pit reduces the debris accumulation; otherwise, debris causes water flow blockage and might jam the sump pump motor due to excessive working. Once the gravel reaches the volume of one inch or more, remove it right away to avoid any negative impact on the performance of your sump pump.

How high should the water level be in a sump pit?

The water level should not exceed two to three inches down there; however, it also depends upon the efficiency of the motor equipped with your sump pump. To know the exact water level on behalf of your sump pump, read the instructions or manual provided by the manufacturer for a certain model.


Gravel reduces the debris accumulation and indirectly keeps your sump pump maintained. But there is a need to remove the excessive gravel otherwise it will block the water flow. Long story short if you regularly maintain the sump pump pit and gravel, it will promote the constant water flow and remove excessive unwanted particles.
