No...it's not the "wave of the future."
Adding a macerator pump inline between a manual toilet and tank or thru-hull is a bad idea...because macerator pumps move material at about 12 gpm, which pumping a manual toilet cannot come close to matching...with the result being repeated "fried" impellers in the macerator pump. Replacing the manual pump with a macerator pump is a VERY poor excuse for a macerating electric toilet. It'll work, though although it'll pull water
in at the same 12gpm rate it's pulling bowl contents out, which fills up a holding very quickly, and it also has a very short lifespan. But it's cheap--only about $150, compared to $300-$700 for a real macerating electric toilet--so it's not surprising that you find one on a charter
boat...toilets are the biggest problem on charter
boats. That's why they all use Jabsco
manual toilets...because they're the cheapest. However, Jabsco
macerating electric toilets cost as much as those that are much higher quality...which is why charter companies rarely install electric toilets.
Btw...your stomach bug had already done a better job of "macerating" than any macerator pump. Adding water
to the bowl ahead of use (why does it never occur to anyone use a cup from the sink to do that???) would allow a manual toilet to work without clogging on TP.
