Sump pit is small


I have the typical sump pit with the plastic ribbed walls. Pedestal pump and i will be installing a sump buddy. The pit is quite small. Could i break some concrete and just dig another hole beside original pit to let water pour into that to give the pump a little more resting time? Thoughts?

No problem. Suggest adding an additional length of 4 inch drain pipe connecting the two pits at about the level of their bottoms.

Sometimes it is convenient to put the backup sump pump in the second pit.

I really suggest digging the first pit large and deep enough to have about 20 gallons of capacity below the level of the perimeter drain pipes emptying into the pit. This provides fewer pump starts and stops and longer run time in between.

Since they don't make pit liners that large, it would be a good idea to line such a large pit with bricks to keep the dirt sides from caving in.

A "bucket" in a second pit next to the first pit and interconnected at pit bottom level will help but might not help much.

Note that the following events take place in the order given:
1. Pump turns on.
2. Pump evacuates portion of the pit above the drain pipes (depending on float switch setting).
3. Pump evaculates portion of the pit below the drain pipes and also more water pours out of the drain pipes into the pit.
4. Level of water in pit bottoms out and pump stops.
5. Water is still pouring out of the drain pipes into the pit.

For those installations where the best operation is had when at least part of the drain pipes are submerged at step #1, the more pit volume you have below the level of the drain pipes, the shorter part #5 will be and the pump will make fewer starts and stops.
