What is this thing on the head inlet hose?

Ok, so there's a white cylindrical thing on the inlet hose to each head. That's right, the one side goes to the seacock and then to the through-hull. The other side goes to the Jabco head.

It has a screw cap on the top, that opens to a small compartment that doesn't go anywhere. The may be for holding fragrence or something, since it doesn't seem to connect with the hoses going in or out.

What is it?!?

It's probably a dispenser of some sort for some head treatment chemical.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Bene,

We have the same unit on our head. It is an in-line treatment system, that helps to reduce odors in the toilet and holding tank. The top unscrews and then you drop a large, cylindrical tablet into the cartridge. Intake water passes through the cartridge on the way to the toilet bowl. The tablet turns the water bluish, just like those tablets you might use in your toilet at home.

The replacement tablets are sold at chandleries like WM, but I am blanking out on the product name. Something like "Waste Treatment Tablets". They are packaged in a small white nondescript box. They are a bit pricey, so I don't replace ours as often as I should.

I think it is a tankette deoderizer:

N.E. Marine : F.C.P. Products Solves boat head odors with head-o-matic tankette (tank-ette) also bilge oil cleanup with bilge blotters

You gentlemen make sense, and that looks like the thing. The only lingering doubt is that the chamber doesn't look like it connects with the intake water. That is, unless there's a small hole in there somewhere. (And I think that there was such a tablet on the boat.)

Yeah, it looks kind of funny in there when you take the lid off. It appears like a sealed chamber, but somehow the water passes through it. I think the design limits the amount of pass through water that contacts the tablet, so that it doesn't dissolve too quickly.
