Now, this may be really stupid, but I can't think of anywhere else to ask... I have a thetford MSD porta-potti in my cuddy, plumbed in for pump out. Been using it just fine for 9 years. Today, I saw a new type of MSD head by Dometics, which uses pressurized water to flush. Looks cool. Was thinking about getting one and swapping it out. Looked at the instructions online, where I read the "usage" section. It said, effectively, to do your thing, then open the "hatch" to the holding tank by pulling the handle, then flushing. Now, I've been #2'ing in mine for years, and I always opened the hatch, valve, sliding trap door, whatever you call it, before sitting down, so that 99% of the time, the business drops straight into the blue goodness tank with nothing left in the bowl. A good flush and close 'er up.

The instructions I read seem to say that you should crap directly on the closed door, then pull it open and flush. It seems to me that that would leave a lot of "residue" on the door and around the bowl??? I can't imagine doing that. Wouldn't that leave the door covered in "it" when you eventually close it up...

Why would it instruct you to do it that way?

Sorry for the grossness of the subject.
 
Without getting too technical, it is likely so you don't splash the blue stuff on the user...

I would use the method that is most comfortable, and instills the most confidence.
 
mchad, I "do" it your way. The other way does make a real mess, and who is going to clean that up? I wouldn't worry about the blue stuff splashing.
 
not sure which model you looked at, isnt' dometic the manufacurer for vacuflush? if so, the ball valve at the bottom of a vacuflush is opened when you flush.. there is a rubber seal which handles scrapping/cleaning residue off the ballvalve... no issue... don't you have a toilet bowl brush at home next to the toilet? same on a boat...needed occasionaly.
 
We had an older version of that in our boat when we bought it. It has a 1.5 gallon water holding tank on it and a 4 gallon poop tank at the bottom of the toilet and an external hand pump to send it to the big tank in the engine compartment.
I thought it was stupid to store up to 4 gallons of "stuff" inside the cabin then pump it to the external tank. So I bought the "non holding" toilet and flush straight to the poop tank located outside the cabin.
Those are good for boats with no tank.
I too opened the knife valve and let it fall in. So skid marks...

I'm looking at the "porta-potti" style heads, not vacu-flush. No ball valve.
