In the past week (last night and last Tuesday), we had lots of rains. The basement near the sump pump area got flooded. The water came out from the two little holes of the sump pump. The two holes (about .25 inch in diameter) are located in the vertical pipe, under the motor and above the T conjunction (of the pump's vertical pipe and the horizontal drain pipe leading towards the basement wall/outside). The holes are in the opposite direction of each other. Are they designed to be like that?
The "leaking" occurred a few times in the past few years. Due to the fact that it was not serious, I did not pay much attention. The problem in the past week seemed very serious, lots of water in basement. I think something is totally wrong.
I searched the messages under the Plumbing here, and did some diagnosis. The drain pipe is not blocked. The float seems to work fine. The pump can start and stop by itself. Water can come out of the drain pipe. It APPEARs that the pump does not have enough horse power to push the water out of the pipe, quick enough. Since I am not an expert on this, could someone help? I greatly appreciate your kindness.

Another thing I noticed that's different is that the top of our sump pump is sealed with concrete, leveled with basement floor. I can only see the vertical pipe sticking out, along with a thin rubber pipe (I think that functions as a switch or float. But not sure). This makes impossible to look inside the sump. Is this commonly seen?
Is it time to call a plumber or I can solve the problem (with your inputs) ?
Sorry for the long note. Thank you so much for your attention.
