."I'm glad I thought outside the box on marine sanitation systems and designed my own."

A WWII surplus Monel head with a 4 x 2 outlet hooked to a bronze 2 inch Edison offset pump has worked for 35 years , with same parts, even flap valves.

Price today would be a concern tho.

Unquestionably the system easiest to live with is a Sealand RV unit , full size that gravity drops into a tank below.

120V RV macerator , or for the spenders with a 40 ft discharge run, an Obendorf 120V waste pump would be choice today..

"Apparently, for what ever reason, they didn't go over well with our charter guests,"

Charter guests are mostly lubbers and anything different from their in dirt house will discomfort them.

Some of the steel house boats in St Thomas use real home toilets that flush with
1 1/2 G of water , from a FW style pump, hooked to a seacock.

KISS is the prime requirement.!

Gravity toilets you say, no say I, been there and done that. Some of us live in the 21st century, actually use our boat, have expectant family or guests on board and have the basic skills/interest to replace a duckbill.

Great thread Jeff, 100% of us use the onboard head and can relate.

If I were cruising solo, I'd do the natural head thing, but every time I hear about a guess on a boat with a natural head, the story always contains a lot of eye-rolling and smirks. Sometimes, technology is just plain stupid and we go along with it. Meanwhile, I just keep replacing my duckbills.

geeez...I guess those million dollar RVs that have'm were designed by Ben Franklin himself.

they are EXACTLY the same toilet as a vacuflush without all the headaches...and if yours smelled...it was either a bad design or something else...

A bit embarassing I guess given the position of the original poster, but we LOVE our two Tecma's...best toilets we've ever had/experienced. I suppose Actic Traveller is way beyond trying a new & different Tecma model, so I'd suggest Head Hunters, which I gather are the new standard install on Flemings. I think VacuFlush toilets are dreadful, 1980's technology...had problems with them when boating in Alaska and hear horror stories from owners with them in slips around me. The diversity of experience and opinion on this topic might suggest installation quality is more the problem than product quality?

Headaches? Headaches would be
  1. Changing out my two perfectly acceptable Vacuflush units
  2. Dumping the gravity tanks on a daily basis
  3. Trying to sell a modern boat with a Mickey Mouse gravity tank or two

We owned a 1981 Mainship that had a factory installed a gravity toilet.

There are still available.

Our Vacuflush units work in Alaska, BC and Washington. They are not hooked into our GPS units. Maybe your thoughts are a Southern hemisphere thing?

In addition to install correctness to insure a satisfactory head experience, I'd add rigorous user training. We tell our guests they assist the head repairman in cleaning out clogs, we've never a plugged head given that user advice.

On a more serious note, this thread once again demonstrates brand and design choices for all things aquatic lead to many types of successful outcomes. Why is that?

Who dumps gravity daily??? I push a button for a few seconds every 5 flushes or so and it's just like any other major holding tank system.... and most REAL boaters I deal with think it's better than they ever have seen on a boat...no MICKEY MOUSE here...people are asking me to upgrade their systems when it come time.

No one is saying change out your marginal system..wait till it breaks and it will....

I don't tell my guests they have to assist the repairman as they haven't clogged since installing them over a year ago and I have been living aboard with full time company.

Shouldn't comment on a system you have never seen or used...I can on all the others because I have used them and hasd to repair most of them.

psneeld,

Why aren't you working as or with a boat builder or a naval architect. You seem to know everything and have more experience than anyone in the industry (based on what you've said).

Trust me, no bad intentions here. Just truly wondering.

Nice to know you are a self proclaimed (over and over) REAL boater. My mistake too, I thought your head needed to be dumped only once per day, now I find out (actually I already knew) it is cobbled together much the same as all other marine heads with pumps lines and holding tanks. It is good to know your unusual head system satisfies your needs, as does mine. As they say, different strokes ----

Exactly...all I'm saying is what mine is and what the other's aren't....I didn't pass judgement on anyone more than the NA that design boats to sell...and we all know how well they actually cruise full time..

If you don't like my posts feel free to ignore...I'm here to learn new, inventive and how to fix/improvestuff...not just read what's regurgitated in brochures and boating mags....

I work in the industry as a tech...improving daily what the NA's fresh out of some intenet training school can only dream about. Never said I had more experience than anyone in the industry...just many of the yahoos right here....

Read a little more carefully and you'll see that....

This is quickly becoming an interesting thread.

Reading the posts I would be lead to assume that the engineers at all of the marine sanitation outfits just have it wrong, and that all of us with commercial purchased marine systems are just barely getting by with our marginal equipment.

Oh, and that we're not "real boaters".

Some of us sound like we are legends in our own minds.

Obviously, thinking out of the box has its advantages. So does thinking outside the boat.

Seems we are good to "go" again. Larry (Healhustler) has put up one of the funniest posts I have see lately.

Very clever.

If one thing has become clear here, it's that heads are a bit like anchors. Everyone has a favorite that works best for them. I can't think of too many different models that have not been recommended as a good replacement for my Tecma, including other Tecma's. Seemingly, every manufacturer has models that are someone's favorite.

It has been suggested that all our troubles with the Tecma are due to our location in Alaska (no it's not hooked to our GPS) Glacial silt has been blamed for our plugged bleeder line and failing pump seals. Perhaps there's something to that, but with the newly designed hose, I have hopes I can get a few more years service before I have to again take it all apart.

Finally, as Chief Engineer aboard small cruise ships it falls to me to discuss issues like water usage and toilets when we do our weekly "Welcome aboard" briefing. I've taken to telling our guests that if they flush anything down the toilet that they didn't already eat or drink, or small amounts of toilet paper, that the toilet will back up and flood their room. I've gotten some pretty concerned looks, but most folks take me seriously, it's not a pretty mental image...................Arctic Traveller
