Leaky Basement Sump Pump Pit

There%26#39;s nothing in what you wrote that indicates you have a problem. The pit and pump appear to be working as intended. In many areas such as suburban Maryland, periods of rain which extend for a few days generate enough water to appear as seepage in sump pits. I suggest check the routing of water from your downspouts. If it%26#39;s not directed away from the house, it could be the source of the water running into your pit. If that isn%26#39;t a problem, I%26#39;d monitor the pump during dry periods as well as wet. Since you%26#39;re in a new house, have you been there long enough to have seen all possible circumstances? It would also be worth your while to investigate an arrangement that insures the pit will be pumped out even in the event of a power failure.
This is a normal situation with a house with a basement. The water is coming from outside and being directed to the sump. Nothing unusual there, simply make sure you have at least 6inches of slope away from your house in the first 10 feet around its entire perimeter. As a home builder I can say the last thing to do is get a lawyer, the only one who wins in that situation is the lawyer and his kids college account..........
