Discharge toilet to sewage sump?

[Brad Borch]

So I want to put in a toilet but only have access to a 2" drain. A macerating toilet would work, but they're about $1000.

Could I do the same thing by discharging the toilet into a sump with a sewage pump that discharges into a 2" drain? Such pumps are less than $200, and the sump and fittings would be less than $100. Plus, if there's a pump failure I could fix it myself rather than have an expensive custom component.

Thoughts?

The sump with pump goes into the floor and discharges a 2" line to either a 3" or a 4" waste line. It also requires a 2" vent for the sump, and then all plumbing going to the sump is plumbed normally including the additional 2" vent for the toilet.

So I take that as a yes, as long as it's plumbed correctly?

Must the sump be below grade?

BTW, thanks so much for the quick response, and for the great site!

Coy? If this toilet is planned for the third floor, say so.

A system like this is below grade.

Toilet will be on second floor. House is slab on grade with radiant flooring so there's no way I can dig into it.
