So, we live in a new house (moved in a year and a half ago as soon as the build was finished). We moved in during the dead of a Canadian winter. Even still, my sump pit would fill and pump put quite frequently. I knew the water table here was high, so not incredibly surprising. After about a month, we got a permit to route our sump to the sanitary floor drain which was great; didn’t have to worry about recycling water and creating a “fountain” effect.
Fast forward a year and a half and here’s the problem I’m facing. Although this past winter I noticed our pit didn’t fill nearly as much (chalk it up to water table changing and grading around the house actually being completed?), it has started filling like crazy over the past few days (mid-April) as the weather has suddenly warmed and we’re dealing with lots of snow melt. There’s no water resting directly against the house, but our whole area has a lot of pooling water. There are even little sloughs created across the alley past our backyard. So I feel like it’s inevitable that this rapid snow melt will affect the water table. Here’s the problem though—as my pit is filling, the water is coming in EXCLUSIVELY through a tiny gap between the bottom of the ABS pipe and the hole cut in wall of the sump basin that receives the inlet pipe. So the pipe itself seems to suddenly not be bringing water in; rather, water is coming in through a relief point through a crack between the inlet pipe and the basin wall (as it is not sealed all too well at all.)
I’ve called around and a lot of people seem to think it’s normal. They say that as the water underneath the slab gets higher/more saturated, the water is simply finding a relief point and is making its way through that crack. (Note that this isn’t a permeable/perforated pit; a solid pit with only the inlet and discharge pipes coming in/out.)
This makes some sense to me. However, I’m thrown off by how it seems like NO water is coming in through the inlet pipe anymore. Could it possibly have come detached under our slab? Most people I talk to seem to think not—they say the inlet pipe will be solid ABS pipe all the way to the outside of our foundation wall, after which point it will T off to perforated drain tile.
Anyway, let me know if this seems normal! I’m stressing over wondering if something underneath our slab is broken/detached and wondering if that’s why water is coming in through this crack instead of the pipe.
