Johnson is a Swedish company...
Their macerator pump has always been identical, but a bit higher quality, to the Jabsco. It's entirely possible that they're making "private label" versions of Jabsco toilets, same as Brydon (a Canadian company that's no longer in business) did in the 70s and early 80s. Or they may be making their own to compete with Jabsco in the European market. Some of the descriptions of how the higher end models work seem slightly different from their Jabsco counterparts. Or...they may have been making toilets for the European market for quite a while and are only just now introducing 'em to the US and CN markets.So I dunno know...but I know who to call to find out, which I'll do next week when I have time.
