Low Flush vs. 3" Line
Posted by Kevin Ball on January 13, 1999 at 00:28:41:
I notice that newer homes in my area have 4" main laterals vs. the 3" variety in my home. Was there
a code change or a smart design issue given the 1.6 gal new construction requirement? Also, since
I do have 3" lines, which low flush technology will most reliably do the job and avoid clogging? My
line goes to a septic tank 5' from the exterior wall.

Thanks! Kevin
