Extra discharge pipe - InspectionNews

I came across an extra section of pipe attached to the main plastic discharge line, and I have no idea what it's for. It's capped on the end as shown in the photos. Any ideas?

Just a guess, but may have been planned to be to sewage pump line. Decided to run a different line so pump would not have to pump as high.
But again, just a guess.
I think it should be removed, could fill with water, extra weight could it break off.

My guess is a line that was run for a vent. Where does the other end of the pipe terminate?

If you can see the red arrows I drew, the line terminates with a cap Also, there was a vent line coming from the sanitary pump that is not visible.

The connections are wrong and where's the vent piping?
Perhaps they abandoned what would appear to be a bad installation?

Does it go through the roof, or at least into the attic? I know this is not likely, but could it be for a later installation of radon mitigation? It looks like it might be the right size.

a sanitary t used in a vertical to horizontal drain line connection is wrong exception is if it is used as a vent.

Regardless, it goes vertically down into a horizontal line through a sanitary tee.

Sanitary tees are approved for use from horizontal into vertical - P3005.1 and Table P3005.1, IRC.

Plus, you wrote up that exposed facing on the insulation, right?

I'm thinking based on some comments, that it was a first attempt at connecting to the sanitary pump. And the pump did have a vent pipe that is not visible, separate from all the visible pipe in the photo.

I did not write up the insulation issue...I guess I was too enthralled with the pipe :0

what is wrong with exposed facing in an underfloor area?

Brian,

There is an area on *each* batt which states something like this:

WARNING: RISK OF FIRE! DO NOT LEAVE THIS FACING EXPOSED! The facing must be in contact with approved building materials.

There are variations of the wording, but you get the idea.
