It depends if you want to hide the pump (underdeck) or have it visible. Depends on space but the top action pump is easier to service.

Not sure where it goes in your poll,
Yeah, I wish I had included another option to cover this kind of dual function. My bad…

As long as you’re only discharging out past the 3 nm limit, or getting pumped out, then I think it would be a Type III MSD.

The PHII is an outstanding manual toilet, but its not a macerating toilet...no manual toilet is. Even putting a motor on a PHII doesn't turn it into a macerating toilet...the motor only replaces the pump HANDLE.

I mainly sail offshore, well outside the 3 mile limit,
Observation of the effluent discharge is an orange-brown coloured stream with no solids,
Even paper is shredded to the point of non existance,
So therefore I assumed it was a macerator,
It certainly grinds it up into nothing, Handle operated,
And yes, It is an outstanding toilet,

Thanks, Brian,

Re: Head Poll v2.0 - what type do you have?

One composting head (Nature’s Head) and one electric head with macerating pump direct to discharge. Composting head is the primary.

On the app, so no poll voting.

Re: Head Poll v2.0 - what type do you have?

Ours does not quite fit but voted anyway.
Still very happy after 9 years with our two electric heads that macerate and gravity discharge where appropriate, or to the two individual holding tanks for later pump-out or gravity discharge where appropriate. Simple push button operation, no smells, all the toilet paper you need - just like home.

Thanks David. It’s clear I should have included this kind of dual function type in the list. Thanks for voting anyway. It’s interesting how so many people have this kind of setup. I don’t recall it coming up much in the first poll two years ago.

Actually seems like the best of all worlds; direct discharge when appropriate (Type I) or hold for pump out when necessary (Type III).

I imagine it doesn't come up as much because Americans tend to have pump outs. In Europe/Med seldom do you see a pump out station though they do exist. Every cruiser I know has a holding tank, and more often than not, pump out/gravity drain to sea when outside the correct limits.

Re: Head Poll v2.0 - what type do you have?

On app so no poll.

Lavac, manual pump to Holding tank. Deck pumpout.

To fix potential clogged pump issues, I placed a quick connect coupling between pump and tank, to which I can connect a second in line pump to clear the clogged primary pump. Also installed a bidet to reduce TP use.

I also think there is a cultural thing going on because I can't ever remember seeing let alone using a composting head on a yacht in the UK.

As for holding tanks, I saw a pump out station in the new Portland Marina a month ago, there are probably others around the coast, but I couldn't name them. Holding tanks particularly on older boats are also pretty rare unless folk are heading to the USE (United States of Europe). We don't have one.

However, inland canals and rivers like the Norfolk Broads have had strict rules for some years. Probably take more legislation and inspections to change things for sea going vessels.

Pete (just going off to read the rules)

I think you’re right Pete. The USA seems to be the focus of poop problems. Canada mirrors America’s laws, but we don’t seem as anal () about it all. No doubt has something to do with sheer density of boaters down there.

A composter is just so easy, and so effective for small crews, or for people who only use their boats for short periods. I’ve predicted that their numbers will continue to grow as laws get more restrictive and enforcement increases.

Re: Head Poll v2.0 - what type do you have?

Few people realize that solid waste is at least 75% water, which means it dissolves in water very quickly, especially after it's been broken up going through the toilet pump. And unless you're using premium TP, which has extra fibers for strength and "creams" for softness, it also dissolves completely very quickly...in fact, the best test of TP to determine whether it's suitable for use in a marine toilet is to put a couple of sheets in a mason jar or glass of water....come back in an hour and shake the jar or stir the glass. If the water is milky and all you see is "snow" it's the same thing as "marine/rv" TP...but if the sheet(s) are still intact or mostly intact, try another brand.) So unless you dump the tank within about 30 minutes after passing solids and using TP, the contents will be liquid... making macerators in overboard discharge pumps and toilets unnecessary.

So nothing is being "ground up" by your toilet, everything is just dissolving.

Btw...if you haven't replaced the joker valve in least two years, you'll be amazed by how much more efficient it will be if you do. And a rebuild kit every 5-6 years will keep it working reliably for 20+ years.

I am just going out on a limb here and I’ll bet that as composting heads become more mainstream, there will be a move towards restricting them.
I believe the reason is how do you dispose of the waste?

A boat that is pumped out the waste goes into some kind of waste treatment system, where does your waste go?

Remember perception is reality, especially it seems with US boats and waste disposal.

I believe it will take some kind of disposal system put in place for the public to accept them, right now they are under the Radar, some fool hasn’t raised the alarm yet, but I think one eventually will.


Oh, and I thought almost every cruising US boat had a waste tank and a Y valve to allow direct discharge. As factory fit my waste tank could only be emptied from the deck fitting by pumping out, I added a macerator pump to be able to empty it when over three miles out.
I didn’t use a diaphragm pump because I rarely use it, normally I’m either discharging or pumping out.
A diaphragm pump cost more, is more reliable and will last longer.
