Hi all,

I am sketching ideas for finishing the basement and it makes sense to add in a half bath. I'm a novice at this and I am having a hard time visualizing how the sewer lines will connect to my main line out of the house. I would think that with the current position I won't be able to tie into it and obtain flow via gravity. I've attached a picture for your review and am willing to listen to any and all ideas.

Thanks!
Jason

Plan on digging a hole for a sewage pit/pump.

Pits with lid--about $60-- Good pumps--$300 to $400

Any more info/articles on this? What about code references?

Thanks,

Jason

That is the standard ,and has been for about 40 years. I wonder if you already have one?

Typically in a house with an elevated sewer line there are two pits---one sump pit for storm water that is pumped outside and another for sewage (laundry sinks,furnace condensation and floor drains) that is pumped into the house hold drains .

This pit will have a sealed lid and a second pipe that is a vent for sewer gas.

Use google images for sewage pit----Mike---

I google'd "residential sewer pit" and I don't think I have one of those. I also traced the main sewer line in the house and it's a straight shot out as seen in the photo I posted above.

What is this? It is in the floor of my basement in the corner. The PVC pipe going into it comes from the HVAC system condensate drain. The top of this thing is kind of sealed, do I want to open it up to see what is in there? Is this something that could be used for the bathroom project?

thanks for the knowledge!

Well I'm not impressed. It's a sump basin with no sump. However, there is an active HVAC condensate line that drains to it. I suppose the builder didn't think about what happens once the basin fills up with condensate? That really frustrates me. :-/

The house may not have had an air conditioner when built. The heating installed should have spotted that.

Often it's cheaper to locate a new pit closer to the bathroom----cutting and trenching across a room is a waste of time and money---

If you wish to cure the pumpless pit---look into a 'condensate' pump --tiny pump/basin that hangs from the side of the furnace and is then piped (tubing) to an over head drain pipe.

The house was built in December '10.

I think I may just go with an upflush toilet like a Liberty Ascent or Saniflo.

Any experience with these types?

Thanks for the info. I was transferred with my job and we sold the house in July '12.
