We need to add another bathroom in my home. We wanted to turn the laundry room into a bathroom. Our contractor suggested using a sump pump for the toilet that will sit on the existing sink. We are also raising the flooring 6 inches from the existing flooring. The scenario is much better since there is gravity in addition the sump pump.
Can you recommend sump pump toilet that we use without having problems in the future?

Thanks

First it is a sewage ejector pump not a sump pump. Ejector pump sit in a crock in the floor, are sealed with a cover. They a plumbed to carry sewage up to the level of the sewer pipe which is presumably above the basement floor. Sewage ejection pits must be vented through the roof.

Show us a picture of your laundry room plumbing.

You don't use a sump pump for a toilet, you use an ejector pump. Perhaps this is what your plumber is referring to. However, an ejector pump requires a separate vent line not tied to the house vent stack. You could also investigate an upflow toilet-Saniflo is one example. My basement bath has a toilet, vanity and tub/shower combo connected to an ejector pump. Works like a charm.

I recommend a M267 ZOELLER sewage ejector pump for this application. Check them out at:

This is the ONLY sewage ejector I have ever used and I have NEVER had any real issues.

Any chance you can rephrase this "a sump pump for the toilet that will sit on the existing sink." so I can better understand what the contractors is saying? I agree, ejector pump is what's needed but your situation is unclear to me.

I am on the same page with Massplumber2008 and his suggestion. The system he is suggesting is well-proven sewer ejector system and the only one our company installs for many years. Milo

Im thinking maybe the OP is asking about an upflush toilet, such as the saniflo? If so, I have never dealt with them, as we always go the route of a sewage ejector pit and pump, but I know some of the fine folks here have some experience with them, and can hopefully help you out.
