If there is water dripping around the pipe that carries water out of the sump pump to the exterior of the home, you want to call a plumber. You want to make sure there isn't a problem with the sump pump lines, or the pump. Not only could the sump pump plumbing be a problem, but you want to make sure you don't have a foundation problem. Here are a few things you'll want to consider.
Leaves, stones, and other debris can get clogged in the sump pump lines. This may prevent water from pumping out of the pipe fast enough and it may be causing the water to overflow back around the pipe. There could be a crack in the pipes, so the water isn't making it to the destination away from the house. The plumber can snake out the lines to make sure everything is clear and functional.
Poor Exit Location
The pipe that leads the water out and away from the home may not be long enough, or may not be positioned properly. This can make the water come out of the pipe, and then get absorbed back into the ground, and then it comes back around the pipe. The plumber may have to reroute the pipe, or add an extension that takes the water even further away from the house.
Back Fill Problems
When the foundation of a house is poured, gravel, stone and dirt is added around it for support. If the back fill didn't last, or if it wasn't put down properly, this could be allowing water to pool back around your foundation at the area where the pipe for the sump pump comes through. The plumber may be able to stop the water from coming through, but you'll have to call a foundation contractor to get the problem fixed.
The plumber may come to your home and determine that the water isn't going to be a substantial problem, and that it's only caused by melting snow or heavy rain. Adding a waterproofing agent to the basement foundation can help prevent the concrete from getting damaged when moisture comes through the walls. If this problem starts in the middle of the night, don't hesitate to call an emergency plumber from a company like South Side Plumbing & Heating Co. Inc. You don't want to wake up to a basement that has water from wall to wall, because you didn't have the leaking water stopped right away.
