Wha valve so toilet does not get into tank?

[Jaybus]

What is the part name so my pump toilet does not malfunction and pump fresh water into my drinking water?

I have a Wilcox Crittenden Head-Mate Marine Toilet.

I paid $50 at a garage sell.
When I pumped the handle it forcefully pumped the water out so I think I am a winner!

you don't hook the head to your drinking water supply ever always use sea water or hook it up to you sink drain and pour water from the faucet in to the sink and use it to flush your head again never , never , ever hook potable water supply to your head

also look up west marine advisory on plumbing ,boat odors by Peggy Hall , and also Don Casey's book on boat plumbing ( This Old Boat )

Ok, thanks. Also I'm installing boat appliances into a converted school bus.
So I have plenty of room for its own toilet tank.

in my opinion, i would have it completely isolated from the freshwater system....

use seawater to flush, and flush it into the holding tank... and pump out at the pump station.

unless you have a watermaker, or a large freshwater tank, flushing the head with your freshwater supply is going to leave you kind of dry and wanting one day

I just read that you are fixing up and old bus why not find a rv site for do it your selfers and pose the question to them

 

[Jaybus]

woodster, Do you know any RV sites that are using marine equipment web sites?
I am installing marine plumbing and sanitation, I dont think it matters.

Does your bus float? Might work out better to scrap the marine head idea and use an RV system. On the other hand, it would be interesting to see if there is an adapter kit.

 

[Jaybus]

are you both insane?

 

[Kermit]

are you both insane?

Three of us have responded. Which one seems sane to you?

 

[woodster]

google is your friend

There are marine toilets designed to be connected to the potable water plumbing, but the W-C Headmate isn't one of them. There's no safe way to do it...you MUST have a separate flush water tank to supply it.

Fwiw, the W-C Headmate was discontinued several years ago. No parts are still available. W-C made the Headmate for quite a few years, so your garage sale bargain could be as old as 15 years or older. Unless you want to continually be flushing good money after bad down the toilet on your bus, you really should install some decent RV equipment. And that doesn't only apply to the toilet, but every system on the bus.

That's my $.02 worth...but it's your bus and your money.

As always, if you want a good answer you have to ask the right question. Not revealing that your install was for a bus triggered some frustration in the responders as they wasted some well intentioned advice. You wanted some specific Marine head advice and Peggie has given you the run down on your unit. Discontinued and no parts available. Don't know what kind of installation or restoration you may be doing for that bus but if you are looking for a low maintenance and trouble free operation ditch that old head and start anew in your search. In truth RV units are better compatible with land vehicles. None of these folks are insane but like I said if you do not like the answer, ask a different question.

 

[Kermit]

I think Jaybus gave up on the insanity of us all. He hasn't been back since the day he joined the site. Sheesh!

what you need to realize is that the component of the system called the toilet or head, can be of several different types, models and sizes, but they are basically kind of all the same for marine or land based vehicles in that they have an intake line and use water to flush and they have a discharge line for the outflow of the waste.

where the separation in marine and RV is the greatest is the way the 2 different systems must be installed.
RV installations are simple and easy to do... as simple as any household installation.

but a boat installation has other considerations that need addressing...
the rocking and heeling motions of the boat...
the fact that the head may actually be installed below the water line...
and no matter if it is above or below the water line, a breach in a line could sink the boat....
the somewhat complicated plumbing of the system (the toilet is a simple object, it has an "in" and it has an "out")
the strict laws regarding proper valving and lock outs...
and so many other things different than what you are dealing with.

thats why you need to stick with an RV site for the proper instruction for what you need...

just because an object, no matter what it is, has been approved for marine use, doesnt mean it will be installed in an RV the same way a boat would have it installed... a LOT of things are installed different for marine applications, than the same object would be in a land based vehicle install. a LOT!!!

Yes but at least his installation won't sink his bus. Unless he drives it into the drink. But alas, I fear he won't be reading any of these oh-so-worthwhile replies.
