Upflush Toilet for a Basement: Add a Bathroom Without Breaking Concrete

How Does an Upflush Toilet Work?
An upflush toilet uses a macerating pump to break down waste and pump it through a discharge line toward the home's existing drainage system, instead of relying only on gravity.
Installation requirements vary by home and local plumbing requirements. Confirm compatibility before purchasing and use a qualified professional where appropriate.

Basement Upflush Toilet FAQ
What is an upflush toilet?
An upflush (macerating) toilet uses a pump to break down waste and push it through a discharge line toward the home's drainage system, rather than relying only on gravity.
Can you install a toilet in a basement without breaking concrete?
In some basements, an upflush system can avoid major concrete excavation because it pumps waste up to existing drain lines. This depends on the home, and some installations may still require concrete work.
What is the difference between an upflush toilet and a regular toilet?
A regular toilet relies on gravity to move waste into a drain below it. An upflush toilet uses a powered macerating pump, so it can be installed where a drain below the toilet isn't available.
Can an upflush system connect to a sink or shower?
Some upflush systems support additional compatible fixtures such as a sink or shower. Check the specific model's specifications and installation requirements.
What should I check before installing a macerating toilet in a basement?
Check vertical and horizontal pumping distances, the fixtures you plan to connect, power outlet access, venting, available space and local plumbing codes. Installation requirements and local codes can vary, so consult a qualified professional where appropriate.
