Those electric conversion toilets are not worth it

My last but one boat had a manual Jabsco, not impressed. Fitted a genuine Jabsco electric conversion, worked OK in the 4 years we kept the boat, still going when we sold it, but horrifically noisy.

Last boat had a manual Lavac, worked well. I replaced the manual pump with an electric diaphragm pump, made a timer for it, so just press a button and walk away. Very quiet, worked well, no issues in the several years i used it.

Current boat came with 2 x Jabsco "quiet" flush electric toilets. One is an early model, works fine but is very noisy. The other is the latest version pump, again, works fine but is noisy, but nowhere as noisy as the other one. I recently replaced the one in the day heads with a Planus, works very well and is almost silent, probably quieter that a typical house toilet. Instructions for guest are very difficult though, "have pee, press right button, walk away" :)
The ‘Quietflush’ brand name should be tested in court. It’s quiet like a huge firework is quiet.
 
Why does this remind me of the ...

Poop Cruise Ship

People really like to be isolated from this reality of biology.
That link doesn't work for me. It's a netflix internal issue because they insist on regio blocking certain things and my account isn't from the UK.

But toilets on boat seem to hit the topic quite dead-on. That might be why. BTW: I didn't know about it and just googled, and that is horrible.
 
But a proper electric WC doesn’t need servicing, it just works.
I wouldn't remove a good quality, reliable and quiet flush toilet. But the cost of fitting a new electric loo doesn't seem to me good value so it isn't on my wish list.
The original post is about the electric flush conversion which I certainly would not have regardless of the brand.
Compared to the Jabsco electric flush conversion the Jabsco manual pump is, without doubt , an upgrade.
 
This thread does somewhat divide into the larger motor boats vs sailing boats, i think.
What is norm, or indeed a *game changer" is apparently rather different in these two worlds.
Limitless electricity is partly it I daresay. Plus the automatic reliance on mechanical systems. But we have enough electrical drain with a fridge, diesel heating, then instruments and lighting.
 
I'm biased towards the lavac. Shut the lid and 10 pumps (for my boat) clears all.
If the hissing noise from the anti syphon inlet vent is to much at night, the lid can be left open as you pump out ....

Plus less concern about fresh water supplies.

But I suspect it goes a bit deeper than that. When you have spent your sailing day pulling ropes, winching sails etc, a few pulls on a toilet pump are hardly noticed. And the experience is mainly about the voyage.
With a motor boat everything else is push button. And the experience is more about the destination and accommodation block.

On the type of bigger “sailing” yachts where the mainsail and jib are both on push button controlled electric / hydraulic furlers, the winches are push button etc, they have generators which run on anchor - again the electric toilets are the norm.
 
We had both manual toilets removed and new, Vetus electric units installed along with a 200l holding tank, plumbing to enable pump out or overboard. Two flush modes, Eco for fluids, Regular for solids plus the ability to just empty the bowl if the seaway is particularly heavy going.

This seems to be a common myth amongst sailors. It's just as much about the journey for motor boats as it is for sail boats. If it was all about the destination we'd go by car.
 
I have a lavac and a jabsco type both fitted with an electric diaphragm pump which are driven by using a time delay push button.

This solves the lack of flush to clear the pipes and prevent calcium build up.

The only downside is the jabsco type needs a flush water pump as well as the discharge diaphragm pump

My Lavac also has a manual diaphragm as well as a backup.

No detailed instructions needed as just a big red button to press and walk away just like the loo at home

A lavac pump instruction are close the lid and flush.
 
In what sense is an electric powered toilet a “game changer”?
He meant a GOOD electric toilet. A fresh water one. Planus, Tecma, etc.

How is it a "game-changer"? Let me count the ways:

1. No more calcification of hoses. No more need to keep flushing for a long time. Because fresh water doesn't react with pee, and your hoses stay unsclerotic.
2. No more clogging. Because a powerful macerator liquifies everything, even TP.
3. No more pumping and pumping.
4. No more worry about sea water getting into the boat via a stuck antisyphon valve, etc.

shall I go on?
 
Yup. Can't beat the manual Jabsco.
Are you kidding?

That's the worst boat toilet ever devised by mankind. The ONLY saving grace is that it is so cheap that you can keep complete spare pump units on board, which can be changed out in 5 minutes. Which is awfully good since you'll be doing it often.

They are: 1. easily clogged; 2. pump ineffectively and laboriously; 3. have poorly designed seals which rarely last as much as a whole season; 4. are flimsy.

If you want a decent hand-cranked toilet, try a Raritan. Incomparably better. Sadly the Crittendon-Wilcox bronze "Skipper" toilet is no longer made; that's the gold standard for manual toilets.

But in any case, I'll take an electric one, any electric one, any day, over any manual one.

I have no experience with the Chinese copy of the Jabsco Electric Conversion shown in the OP, but I have used the original Jabsco Electric Conversion for 16 years in my guest heads. It's noisy enough to wake the dead, it's true, and has a few other design flaws, but is immensely robust and powerful and does the job. Another drawback is it's ridiculously overpriced.

But they have the advantage that they are standardized to fit the classic Jabsco toilet base, so can be swapped out in 5 minutes for a spare, including a spare manual one if you prefer. It's a good choice.

I have a friend with the Chinese copy, and it seems to work well for him. I don't know how long he's been using it.
