My condo is 6 years old with a sump pump. The liners has two 4 inch drains running into the pit. The issue is the water, running constantly after heavy
How long do you think it takes for rain water to soak down 2-4-6 feet to the perimeter drains, and then for the soil to dry enough to stop releasing water to the drains? Different soils, construction techniques, and backfill materials when the structure was built will effect the drain rate. It’s when the water never begins to drain, or never stops draining, that you may have an issue.
