The Groco K-H is a hand-operated marine toilet from the K Series, with a household-size bowl and an all bronze pump. The pump uses a 3" piston mechanism, and flow is adjustable up to 4 GPM. A foot pedal lets you choose how much flush water is used, so there are no valves to shut and no hand wheels to spin. It can be installed above or below the waterline.
Our take
The foot pedal water control sets how much flush water is used, which leaves no valves to shut and no hand wheels to spin. The 3" piston pump is all bronze, with flow adjustable up to 4 GPM, and as a hand-operated model it needs no power.
From our buying guide
A vessel with installed toilet facilities must have an operable marine sanitation device that is labeled or certified. EPA says untreated sewage may not be discharged within three miles from shore, and in a No Discharge Zone treated sewage may not be either.
Check before you buy:
- You have what it needs, since heads may call for 12-volt power, through-hulls and seacocks, or a separate vacuum source.
- It fits the compartment, since Jabsco says an electric toilet needs more space at the rear than a manual one.
- If it could sit below the waterline, you'll fit a vented loop as the maker specifies, since Jabsco warns the vent, not the loop, is what stops the siphon.
