Toilet installation
Posted by Mike Tietz on October 16, 2001 at 22:10:09:
I am installing a new toilet in a Park Model Travel Trailer that was manufactured with out the standard RV unit.
I am looking at the Briggs Vacuity toilet

Question: is it better to plumb in 4" piping and a 4" toilet flange or 3". Any benefits of one or the other sizes? Most RV plumbing is 3"
