Sewage Basin


I am dry fitting the sewage basin. Based on the position of the discharge line and the hole in the basin, this is what I am ending up with. The basin is protruding about 4 inches above the floor. Is this normal or shoud I find a way to lower the discharge line?
Appreciate your advice.

Re: Sewage Basin


Your sewer line is right below the floor? Is that the port you want to run the toilet line in?

No digging deeper wil not help - the hole is already lined up on the side. If I go deeper then I will have to drop the pipe lower under the concrete.

So the toilet and shower discharge is under the floor. They empty into the basin. So right now the hole in the side of the basin and the discharge line is lined up. Does that clear it up?
So it looks like I have to lower the discharge line (the inlet) or leave the basin sticking out?

Usually you would place the basin first and plumb to that?
Do you have it in a place where a raised floor would work?

Hope the picture helps. This is a roughed in pioe under the concrete. I am now trying to insiall the basin. The circled area shows the pipe in the current location - thats along the side of the pit about 3 inches under the floor. So If I want the Basin level to the floor, we lose this alignment.

This is what I would look at.

Re: Sewage Basin


Thanks - I will look into this - not sure I will have enough space in the pit. There is only about 4 inches of wiggle room.

It sounds easy if you say if fast.

Re: Sewage Basin


Curious, did you cut the hole in the basin?

No - they are sold like this. Would adding a layer of concrete around the basin be a possible solution?

Re: Sewage Basin


Personally I see no problem with leaving the basin top above the floor line, other than unsightly.
And as far as adding concrete around it, should do a good job of protecting it.


Or, cutting the protruding riser may be a option, but you would likely need a different top. The MFG may have a top that seals on the I.D. of the riser in lieu of the current flange.

Re: Sewage Basin


Close up theprecut hole and cut anew one closer to the top of the sump.
