How much water should be in my sump? - Reader Question

Answer - whatever the height of the water under your home should be the level that you see in your sump.

Sump pump in basement with water in the sump location
This is typically a question that many homeowners have if they have an open sump pump pit location somewhere in their basement. Looking into the sump basin you can see water sitting in the sump. There are, however, a few things that will effect what you see in the sump location.

Things that effect what you see:
1.) The sump has openings to allow water into it besides pipes dumping into the location. - If the sump has openings and is allowing the water underneath the home to have access to the sump then you will be seeing the actual level of water under your home. If there are no holes or entry points then the water you see could be what is left over after the pump switch turns off.

2.) weather conditions and soil saturation - You will see more water in a sump location typically while there is rain coming down and when the soil reaches it's max saturation point.

3.) the height of the sump pump relative to the floor - sump pumps that are deeper than 17 inches in the ground will see more water. If you have a deep sump location you will see more water because there's more water the further down in the earth you go.

If you're sump is working properly it will react with the rise in the level of water and remove it accordingly. If you're seeing long standing water it's possible that your sump location is too deep and needs to be updated.

Having a sump location in your home will allow water to collect. Don't be surprised when you see water, but do be cautious with how the water is being removed.
