Before the rain comes pouring down, now would be a good time to clean out the debris in your catch basin and check that your sump pump is working well. This is a good way to ensure that the debris will not interfere with your sump pump capacity, when the rain hits.
The possibility of a flood in your home or garage is very likely, and the damage will be greater, than taking a moment of time to clean out the catch basin and making sure your sump pump is in good working order.
Consider cleaning your catch basin and checking your sump pump at least a couple of times a year. This will assure that your drainage system is functioning smoothly, when you need it most.
