Why do you need a tap for the sump pump?

No, but as you can see from my picture, the sump pit was completely sealed by concrete, so I could not see anything other than leaks from fittings on discharge pipe. This I noted on the report. Thanks again.

It is still stupid to discharge sump pump water directly at the foundation. I wonder if the pump runs often (keeps recycling the same water!)

Yes, and it was noted on the report.

David,

Excellent call. It is indeed a sewage ejector. One pipe is for discharge and the other may be for venting.

Make sure it is connected to a simplex receptacle and not to a GFCI.

Also ensure that the top is secured and sealed.

Check valves are needed…

As is an alarm.

I will add in that in many jurisdictions the septic system is licensed by the local environmental department or health department… as such they have a maximum daily capacity like 300 gallons in our area. If a sump was hooked directly to the septic tank, there is no way to determine how many gallons is being pumped into the on site waste treatment facility, and in my jurisdiction this would void the license and subject you to civil/criminal fines and fees…
