New boat question

It is possible to have a manual head with a discharge seacock, a holding tank but no macerator pump. The Y valve selects the discharge port or the tank. When is discharge mode whenever you use the manual pump, it discharges overboard. I didn't know that until earlier when I looked at the Xylem web site for manual head options.
I did not know that! My experience is with porta-potties, PP's with pump-out, and then right to Vacuflush - none of the manual/electric options. Thanks for the clarification.

That sounds like how too many sail boats were set up in the past, and many still are today. But, doesn't that mean that the only way to empty the holding tank is shore side pump out?

Actually, many boats, both power and sail, have a holding tank (regardless of type of head system) with no macerator. It's not a "bad" thing to NOT dump sewage in the ocean...
 
I agree, Dennis, that's not a bad thing. My negativity was directed at the straight overboard discharge system, which brought back memories of the 1970's-80's, when it was common to see a brown trout, or a handful of toilet paper, floating through a mooring field, or even a marina. I think that was a major factor in why Florida pretty much declared war on transient liveaboards back then.

I've read (just assuming it's true), that in some countries they actually allow overboard discharging in your slip!

Brown trout... Baby Ruth candy bar... either way, yuck!
 
Do you know the cost of each of those 3 options from Grady? Also, do you know the brand name of your porcelain bowl?
$2285 for the manual flush, $3075 for the electric flush (porcelain) $965 for the plastic toilet with macerator pump, $430 for the plastic toilet. All have holding tanks, the first three have macerator pumps with overboard discharge capability. Jabsco is the brand. These prices are from the Grady options list for 2020.
