The one I saw last month used A 1 inch .
I have seen quiet a few and they work great better then tearing up a lot of concrete and much cheaper . One has been running for ten years

Assuming the question refers to "standard pipe sizes" Trap arms found under most sinks can be as small as 1-1/4" as Gerry said. I have never come across a tail piece smaller than 1-1/4" on a standard size sink.

I believe Sandiflo systems is not free flowing and requires grinder/blades to shop up the solids as it passes through.

This is my first reply as I just joined NACHI on Monday, I hope my response has not offended anyone.

Hi Roy, good one........... you got me I was only thinking about gravity wastes when I wrote the question, IRC states that all discharge piping of grinding pumps may not be smaller than 1.25 inches, however it also states:

P2723

MACERATING TOILET SYSTEMS

P2723.1 General.
Macerating toilet systems shall be installed in accordance with manufacturer's installation instructions.
P2723.2 Drain.
The minimum size of the drain from the macerating toilet system shall be 0.75 inch (19.1 mm) in diameter.

Nice catch mate
