Thanks in advance for any advice. I would like to know if the 2" pipe with a 2 x2 x 1 1/2 tee is the normal way of connecting the discharge from a grinder pump (pipe on left of photo) going to pipe #1 which rises above aprox 7 feet to the main soil pipe (not shown ). The vent pipe (pipe #2 on right ) I believe is a dedicated vent that goes to the roof. My question is, should I separate the two pipes at the tee, and run the vent pipe direct to the sump can, and separate the discharge (pipe # 1 on left) and pipe direct to the pump discharge? Will it work with sewer slurry ( that would stand in the pipes due to the check valve) as shown? It would seem that, as shown, it would create a large trap up to the level of the main soil pipe. Also, the vent pipe (on right) has one inch of slope toward the vent side, that seems odd to me? Another thought is, was the tee just a method of being able to test the rough in piping prior to making the final connections to the sump? The house was built in 2005 and is located in NC.
Thanks
