I suggest a pit with at least 3 cubic feet (a little over 20 gallons) below the rims of the perimeter drain pipes. An 18x18 inch square pit (clear space, not counting a brick lining or gravel fill) would need to extend 16 inches below the drain pipes. The pit may be close to the wall even though it is much deeper than the foundation footings.

This allows longer pump run times and fewer on off cycles. This allows more time for already accumulated water in the drain pipes to make its way to the pit before the pump shuts off, if the turn on level was a bit above the drain pipe rims. This reduces the impact of water in the outlet pipe falling back down if the check valve did not seal completely.


Do you get coverage you can count on? From the bag of fertilizer? From your lawn sprinklers?

Sump pump operation

Just an update. Now that the monsoons are over, my basin is staying below the drain lines that enter the basin. All is good.
