So, I guess this would mean the groundwater level gets a little higher, and is thus messing with the sewage well by applying greater pressure and, now, getting to a higher level where there is a place for water to escape. The drain tiles actually partially fill with water before it ejects the sump. I think this goes back to the fact that my new sump allows the water level to get much higher before its pressure triggered switch goes off. I guess after I plugged the bottom, the groundwater slowly made its way up and started coming out that way. The water is dripping (very slowly) through that. There is a very small gap between the pre-cut hole in the basin and the 4" PVC coming in. I noticed it started getting wet again - but this time it was coming from the inlet for the incoming ground drain pipe. Its a putty that is specifically made for underwater repairs, and if you know JB Weld you know that stuff sticks. So, my thought is someone messed up, or was lazy.īecause the thing is pinned in by several inches of concrete, I opted to try plugging the holes. My guess is that a sump well was installed instead of a sewage well - it looks identical to my sump well. To my surprise, there were machined holes along the bottom. I went ahead and and took the pump out and drained the well with my shopvac.

I'm really hoping to avoid replacing it, as I'm not sure how I'd get the PVC from the AC drain through the well while installing. If I find it - is there any way to patch it? I believe the well basin is fiberglass. My plan is to dry out the well with my wet/dry vac and try to get visual confirmation of a leak. If anything, the crack is on the bottom or around the sides near the bottom. Perhaps the higher groundwater level is to blame? The thing is, I could see no sign of water coming in from the sides of the sewage well. Does this sound right? It may be related to the fact that I recently had a new sump pump installed (ie not my sewage well but the sump) which triggers at a higher waterlevel than the prior one. My conclusion is that it must be groundwater seeping up through a crack in the basin. I also left it detached for some time and saw no water coming out of the pipe, yet the well was still slowly filling. I pulled it apart to look at the checkvalve.I found the valve was working. It also does not appear to be backflow coming from the ejection pipe. It is not coming from either of the two sources (washer or AC).

Further inspection showed its filling very slowly at a constant rate. Recently, I noticed the ejector pump going off periodically when neither of those items were running. My basement has a sewage ejector basin for the washing machine and A/C condensation.
