Basement plumbing
I am planning on finishing my basement. I was going to take advantage of the roughed in bathroom (sink, toilet and bathtub pipes coming up through slab) but wondering how the plumbing actually works. The main waste line seems to exist the basement chest high. How does the waste from the roughed in basement bathroom make it up to chest high. I have attached a picture. The 2.5in line at the top of the picture was originally about 3 feet longer and capped. I cut it off and capped it to get it out of the way. It did not extend down to the sump in the floor. There is another capped off line that connects to the main waste line leaving the home atabout the same location.
The bath tub rough in is at the bottom left of the picture and the toilet and sink drain pipes are off the left of the picture.
Do the 3 roughed in drains go to the sump? and then should be piped to the main drain line some how? Why would the over to the sump be taped off and line disconnected? Perhaps because the basement had never been finished?
Curious to learn. Perhaps there is a ready webiste reference I could tap into?

Thanks Norm. I have owned 5 homes in the past and never had an injector. When I saw the pit in the floor when we moved in, I assumed, without paying too much attention that it was a ground water sump.
Always a time to learn something new.

Wait a minute. Now I'm confused. Do you have sump pump? It should be totally independent of the sewer system and not tie in to you drains. It will use an ordinary sump pump. So you're saying you think that grated pit was meant for a toilet?

Need more info!!!
Where does that pipe you marked go?
Is it a vent?
Is the pit a drainage water pit or is it to be a sewage pit?
A sewage pit has to be sealed. Can you imagine the stink if it was left open or poorly sealed like a ground water sump pit.
Ods are that it was meant to be used as a sewage pit but you will have to confirm this.

It looks to me like you're plumbed for a sewage ejection pump, but one hasn't been added yet.
Do you have 2 separate sump pits? One for ground water and one for sewage? The sewage one is usually bolted closed while the ground water is usually just covered. You'll also have to confirm where water goes when you pour some down into the pipes in the ground.
The two capped pipes at the ceiling imply to me that it's prepped for a sewage ejection. The vertical pipe is your vent, likely going up through the roof. The capped horizontal pipe behind it looks like it would be where the sewage ejection pump would pump the drain water.
