Water is not an issue, presure is not an issue,
Can one use a household commode, and have the solids go through the macerator before going into the holding tank. And preform effeciently

Newest household commode uses 1.5 gallons of water the macerator (sp) can be moved to be above the holding tank. My intake for water is from the lake from a on demand water pump. Or from the water line on the dock.

Being very hard headed I have been directed here several times but thought the plumbing section addressed this, have been told to forget this idea will ask one last time at the correct section b4 forgetting the idea.

Only using it as instructed, if it wasnt eaten it doesnt go in
 
Yes, you can probably MAKE it work. It'll probably cost you more than you expect. No I don't think you'll be happy with the results.

I doubt the macerator would pump fast enough to keep with the flush. And it'll still fill up your holding tank pretty quickly, unless you're just dumping it overboard and not telling us. The fine if you get busted will get your attention.

What do you have on the boat NOW and what's wrong with it????
 
Dale,
This is the place to be for your questions. Hopefully Vic will see this post and offer his opinions. Vic is the moderator and knows more about marine sanitation devices (heads) and the necessary plumbing than most of us put together.
 
ok that is something I can understand where the macerator wont keep up with the outgoing flush.

I guess I was thinking of a small tank the solid went to the macerator chewed it, then it gravity fed it to the holding tank.

No this boat isnt ready for use we are still wiring, plumbing, gen, and doesnt have gas tanks yet or AC, only flushing clear water, still lots of issues on the unit.

Its a crown head unit, that i have replced the pump impellar, and cant make it work with the black ball, which i put a new one in, it still would only work with/Out the ball, spring is the next thing to replace, but both balls seemed to stay seated. No burs felt on the houseing inside the pump. Seemingly to me the pump would suck hard for what i know when using a intake from a pal next to the head?
W/Out the ball a week or so it stil holds it prime
 
if you don't' have a macerator between the head and the tank, then solids are going to stay at the bottom of the tank when you pump out and eventually you're going to have a tank full of unpumpable solids...

I'm thinking out loud here but... if you want to use a household toilet, you could use a large PVC pipe from the toilet which feeds into a macerator to send the stuff in semi liquid form to the holding tank. if the PVC pipe is long enough to have enough volume to hold at least one flush and if gravity feeds into the macerator, it should work. doens't have to be vertical, just enough angle to the macerator.

I wouldn't do this on a boat, but we're talking houseboats here...
 
dalehollow, I posted my thoughts over on the other Forum, to your original posting.

Pascal, are you implying that a houseboat isn't actually a boat, but more like a floating travel trailer? [:-eyebrows]
 
well, i think its closer to a trailer than a boat, isn't it ? more like a trailer on a barge ? unless you get into the real fancy new ones what that built more like boats... :-)
 
Aw comon Pascal, you're talking about MY boat, too. It even LOOKS like an RV (Recreational Vessel).

Dale, the idea could be made to work; but you'd have to flush the toilet, THEN hold down the macerator button till it did it's job. Sooner or later someone is going to forget and then the first tank or the pipe would overflow (yecch!). I don't think you could rig a float switch to do it automatically.

I still think the ultimate issue is going to be filling up the holding tank with all that water.

If your Crown head RUNS I'm sure it's repairable, and probably for less $ than a household toilet, tank, plumbing, water pump, macerator pump and aggravation. I'm sure Vic can help you figure it out.
 
ok devils advocate...

Presurized pump to the tank of the household head.. Regulated by the ball-cock ( just get a charge out of typing that one ) The old head with repaired maecerator is fitted with a permamenet piece of gel coated marine plywood sealed on with a 4" hole in the center as a "seat" the plywood is then fitted with a 4" household toilet seal flange. The marine head mounts under the floor of the household such that the household toilet dumps its 1.5 gallon into the bowl of the marine head.. which in turn is flushed on a cycle switch for n-seconds. Marine head pumps to the holding tank and its all done...

Yes failure prone, but all the comforts of home..

All that said I bought a new sea-era this year.
 
From my point of view, as His Royal Highness, Master of the Whole Darn Boat, I want a comfortable throne.

I also want and expect it to work first time, everytime, as it is demeaning to the Royal Personage to swab up the residue and otherwise interact intimately with the marine sanitation systems.

So, for us, an approved Marine Head is the way to go. In Our Humble Opinion. ;)
 
Bill: I just replaced my vacuflush seat with one from HD, it was an exact fit so VF is one that is home sized. I am not sure if that meets your comfort requirement though as they dont make recliner styles.
 
Dalehollow,

If the Crown Head is working, why not just use it-as is? What is the object of your question? Larger bowl and seat? Pressurized fresh water instead of lake or river water? I don't understand what you're trying to achieve by this exercise.

It can be made to work in the configuration you described, but it's a very round about way of doing it. In my opinion it would be like running your car with the gas pedal floored all the time, then controlling the actual speed going down the road by pressing on the brake. That'll work, too - at least for a while, but it isn't a real good way to do it.
 
If you really want a home toilet, look at a sewage injector pump in a basin that would then feed your holding tank. Just like putting a toilet in a home basement. Or try searching for Zoeller "Qwik Jon".
