Electrical Connection to Submersible Pump

Hi,
I have a rain water catch basin in the middle of my driveway and a submersible pump that evacuates the accumulated water to street. Last season all was well bu now after the pre-season cleanup the circuit breaker fails every time the pump starts. The pump is hardwired to wires that have been drawn under the driveway ant to the basin but the connection is inside the basin with silicone twist caps. Can you recomend a better application for this electric connection? I am afraid that by moving the pump I might have introduced some moisture into those silicone caps. Any suggestions?

Thanks!

Mike

I would remake the connections using a shrink tubing set made for installing submersible pumps in a well. Any local pumphouse should have them
