You connected a manual toilet to your fresh water
system? That's a BIG no-no! Groco doesn't make a toilet that's designed to use onboard fresh water...and connecting the EB or K to the fresh system is even more risky than most toilets because those toilets have a very nasty habit of recirculating when they get enough age on 'em to wear down a machined part in the pump.
To answer your question: The Model K electric Groco Model K instructions
is what I call a "hybrid" toilet...a manual toilet to which a very expensive motor
that does nothing more than replace the pump HANDLE has been added. It's still the same manual pump. The Raritan
PHEII is another one. I'm not a fan, 'cuz putting a motor
on a manual toilet turns a perfectly good manual toilet into a very poor excuse for an electric
toilet. The motor pumps it faster and with a shorter stroke, causing it to take longer to prime each time, wearing out seals
, valves and o-rings a lot faster, which means more frequent rebuilds are needed...and also to choke on flushes that slower more deliberate manual pumping could push through. Those toilets also cost considerably more than electric toilets that are designed to be electric toilets. And then there's maintenance
...manual toilet pumps require lubrication and frequent maintenance
..."real" electric toilets need no lubrication and no maintenance beyond a rebuild
every 5-6 years.
For some reason, sailors like the idea of a toilet that can be converted to manual in the event of a catastrophic power failure. Seems to me, though, that if you don't even have enough juice to flush a toilet, whether you can or not is the least of your worries...'cuz you won't have nav equipment
, communications equipment
, lights, auto pilot, and prob'ly not even an engine
...but you WOULD still have a bucket!
So if you want an electric toilet, buy one that's designed to BE an electric toilet...don't settle for just a motor that replaces the pump handle. Practical Sailor just did a review of electric toilets...they rated the Raritan Marine
Elegance Raritan Elegance toilet
"best of show" and the Raritan SeaEra Raritan Sea Era
buy." If your budget
will stand the Groco model K electric, there's more than enough room in it for the Elegance...I'd go with that one and the optional "smart flush" panel.
