So the water IS clean flush water, not backed up flushes??? If so, yes, emptying the bowl SHOULD keep it drained...but as you'll see from my replies to others it doesn't always.

This isn't "normal" for all electric toilets...it's a function of gravity and water's pesky insistence on running downhill. If the solenoid valve or if there's also vented loop (vacuum breaker) in the intake is above the bowl, whatever water is left in the line when the flush button is released will continue to run downhill into the bowl....the higher it is, the more water will be left in the line to run into the bowl.

Pedal operated VacuFlush toilets have a water valve on the back of the bowl that isn't electric. The pedal operates it. Because the water valve is on the bowl, less than a tablespoon of water is left to run into the bowl.
So ideally the black water tank should be lower than the toilet?

Ideally, yes. And also within 6' of the toilet. But not always possible...in fact, rarely possible on most sailboats. So work-arounds and often a little extra effort are needed keep the system trouble free.

Are you ever gonna confirm whether the water in your bowl is clean flush water or dirty backup??

Ummm 14 is my last post. If you meant 13, it seemed to me to be just a question.

Peggie, you know I'm easy to confuse. You wouldn't gas light me would you?
This is what I see in Post 14 by Evil Rabbit.

"It seems to be a little bit of whatever was in the bowl. So yeah, if we empty a bowl with some pee, some of that pee water is returning."

Re: Does your electric head bowl slowly refill once you have emptied?

If anyone is being gaslighted, it's me! What I'm seeing:

#11. A post from me that begins "So the water IS clean flush water, not backed up flushes???
#12. A post from me that begins "There is a vacuum break, but it's the solenoid valve that turns the flow of flush water on and off...kinda like a faucet.
#13. A post from evilrabbit that asks "So ideally the black water tank should be lower than the toilet?"
#14. My reply to him that begins "Ideally, yes. And also within 6' of the toilet.
#15. From HopCar telling me he confirms that it's black water in post 14. The first time I'd seen what you quoted.

On my screen HopCar's post that begins 'Peggie you know I'm easy to confuse is #21...what number is it on yours?

This is totally bizarre!

It's dirty yeah. Seems some water is following gravity back down the waste inlet pipe as our black water tank is bulkhead mounted above the toilet. Means we have to flush 3 times now; not ideal when we using fresh water. To start, going to see if we can move the black water tank so the hose flows down from the toilet.

It gets even more bizarre...now your post "peggie you know I'm easy to confuse" is now #17 on my screen and my reply is #18....which SHOULD make this post #19....

And you think YOU'RE easy to confuse???

Re: Does your electric head bowl slowly refill once you have emptied?

The only way to stop your problem is to flush each time using at least two bowls filled with clean water. This way, when the anti siphon does it's job and empties its contents back into the bowl, the waste hose filled with water won't contain any visible waste. It's also good for your system to keep the waste hoses from permiating with odor.

If you have visible waste coming back into your bowl, you're not flushing with enough water.

Problem is the two fold: bowl refilling with water and not staying empty is a problem in bumpy conditions; quantity of fresh water needed

Re: Does your electric head bowl slowly refill once you have emptied?

I think the best thing you can do is move the tank lower than the toilet. You may have to get pretty creative but it's the best long term solution. Tanks are available in a lot of shapes and sizes. Ideally the discharge hose will slope at least a little downhill all the way to the tank.

Switch to salt water flush and flush using two bowls of water. Both problems solved.

Trying to find the space to lower them and also switching to a smaller hose to reduce the volume of liquid able to return to the bowl.
