This toilet was reinstalled to replace the 2006 Briggs Maelstrom, which frequently clogged & had an extremely poor bowl rinse. This toilet not only has a much better bowl rinse but also is relatively clog resistant being that it has a large, fully glazed trap way, which is something the Maelstrom didn’t have. This toilet features a Fluidmaster 400A fill valve & a Niagra Stealth vacuum chamber for reliable vacuum assisted flushing. The flush is very strong & powerful on this toilet.
