My husband and I recently bought a new home and experienced a basement leak from neighbor's home (semi attached) -- sump pumps were later installed. Our neighbor's sump pump is running with water 24/7 non stop. Our sump pump runs but not as frequent as our neighbor's. We are worried that we will have another leak in our basement, especially if our neighbor's pump stops operating. What can we do to prevent having another basement leak?

Have you talked to your neighbor and asked if there's a problem?

Might give you some insight on what to do next.

Are both basements totally in ground? How old are the houses? I build foundations and excavate and also fix many basements from leaks. You have a serious problem with the water table. Is there public water there?
How old are the houses?
Just on the get go someone's going to need a back up sump pump that's set higher than the first so when that burns out it will kick in/ Sump pumps aren't designed to really to run 24/7 and burn out. Where is the discharge from the sumps? Away enough from the house not to recycle back to basements.
At this point nothing can be done to stop the water unles we narrow down some things at best
Need more details

Yes, both basements are totally in ground and the houses are new construction -- less than 6 months old.

Ho boy here we go. Have you talked to the builder and what was said?

Let me guess the response one the ground settles it will go away.

Is it constantly raining there and what about the down spouts how far out from house?

Are the houses sitting on a total flat area or are you in a development lower end. If you can me the topography pg the development if you are in one.
From the back or front of the house do you have any grade drop and how many feet in drop?

If so I try to eliminate the sump pump and drain the basement out of ground even if it has to go 100 feet or more

More details please

Thanks for responding. We are in nyc -- there has not been a lot of rain. The homes are sitting on a flat area and the down spouts are approximatly 25 to 30 feet from the homes.

Well keep an I on things and watch the sump pumps and see what happens later. I would be ready to have a second pump a hand. If there's anything to get ruined in basement I would put those up on wood so if the pump fails there some time to replace it and the things in the basement won't get wet so quick. Hopefully when the grass gets established and ground tightens up this will slow down
