My sump pump has been going off about every 3 minutes in the last 2 days. I need to open the pit to see why it is doing that. I'm unable to open the lid as I see another big pipe going into it. Please see the picture below (click for full size):
1) Does anyone know what is that larger pipe on the right going into the hole? I know the smaller one takes the water outside.
2) Also, how can I open the lid with that larger pipe in there? Do I just slide it up? I don't want to damage it and this is the reason for this question.
3) Finally, does the power plug look fine or do I need like another adapter before plugging it into the outlet?
