Sump pump removing a lot of water from basement. Is this normal?

There will be a non-return valve on the outlet to your pump. Check to see if it is sealing. If not the water that has just been pumped may drain back through the pump into the sump and so on and on ....

To check this you could pour some food dye into the sump and if it gradually clears then this would indicate that fresh water is diluting the dye. In this case you have a healthy spring source , but that is a harder problem to solve.

The water table should not be anywhere near the level of the house, or it would have never been given a permit. However short term water saturation is a different matter. Some houses do sit in water level for short periods. Often you see houses with 2 sumps. If you have that much pumping, you should get a battery back up system. You know, the power goes out when you get a really big storm.

Be sure the water goes to a proper drain or at least away from the house. It could be pumping it out of the sump only to have it return from outside the foundation back to the sump. Does the sump level drop when its pumping:

no, it does not sound normal. i cannot answer the question, but maybe give you something to try. first, is your basement damp all over? second, can you easily remove the sump pump from the pit? if so, perhaps you could shut it off, and remove it after it has removed the water. then observe the pit to see where the water might be coming from. like maybe it might come from one side or the other, or up from the bottom. it might give you a clue. best i can offer. also ask landlord, or person you bought it from. if purchased, then seller may have some responsibility. good luck

Yes and no. Some people use water as a substitute for food. So in this way it is very unhealthy and will backfire. Eventually when you loose what you want you will gain it all back and then some. Mostly because you didn't change any bad eating habits. You just starved yourself. Now if you do that in a sense of more water and less sugary drinks than yes it's okay. It will probably help you loose weight. It's one step to eating healthier and eating better leads to a healthy weight.

you might juts be built on a high water table.

check with your water board.

why not buy a water tank and keep the water you are pumping out to use in your washing machine, or toilet?

really lower your water bills, and help the environment

sounds like when they dug your basement in they hit a spring. how old is the house? talk to a geological survey company in your area. They may be able to point you in the right direction

There might be water coming in from other place. the catch basin might not be properly water proofed.
