New electric toilet??

[Robin]

Just one word of caution.You may find that depending on your length of waste pipe that the fixed electrical pump period may not get your discharge out of the pipe.On my boat the exit and inlet pipe are in a weird position under the bunk in the main cabin.This means that there is about 5m of pipe between the toilet and the exit stopcock.(Why it was designed like this who knows).On my boat it is a standing order that a minimum of 15 pumps of the handle of the Jabsco to make sure it is clear.I asked about this at the Boat Show and was told that the Electric Lite on may need 4 or 5 flushes to clear that distance.As we reach the age where night time trips are usual I decided to stick with the manual pumped one.
As it happens since converting to the lock down pump it has performed faultlessly

Thanks for that Ditchcrawler, I hadn't thought of it from the exit strategy point of view but had wondered how to duplicate the vigorous pumping for times when things get a bit congested down the line. We had two normal electric Jabscos on the mobo that we lived on which had very powerful user controlled macerator flush pumps and also had 1" pipework on the outflow sides which I was told produced higher velocity flow than using 1.5' so was therefore more aggressive at moving things along to the holding tank ( which on that mobo was probably 20ft from the forward loo and 10ft from the owners aft cabin one). Our new sailyboat has just the one loo that is right next door to the vertical holding tank in a locker but involves an upward journey first to get to the top of the holding tank. that might help explain the mucky drainback that occurs with the electric conversion of the original manual Jabsco, that maybe it's modus operndi (and noise)doesn't encourage lengthy enough pumpout cycles. All food for thought and also making me think about simply replacing what we have with a brand new twist 'n lock manual Jabsco and using the extra money save to buy a complete new pump assembly for same to carry as an on board spare, that being easier to swap than to do a rebuild/service from a spares kit of the in situ one. Sometimes simple is best.

There's a small workaround that allows water from an external source, e.g. a bucket, to flush copious amounts through the LITE. After the toilet circuit is first powered up the initial touch of the flush button turns the impeller/macerator for several (10?) seconds, easily long enough to empty a full bowl. When we pack the boat up we do this several times, filling the bowl with a hose pipe then powering off and back on again. Not something you would want to do on a regular basis but very handy occasionally.

in our case making sure to remember to divert that flush overboard and not just fill the holding tank with it! not so easy over here where the poop police insist on diverters being locked with cable ties or similar to prevent accidental overboard discharge and they board and inspect boats to check on it up to 12 miles offshore even. since we are marina based on the ICW a check is always on the cards.

They have some great eletric toilets in Japan - more controls than a 747 - with ventilators, extractors, noise markers to mask bodily noises and plops, seat warmers etc they are the dogs b***ocks.
Why not go the whole hog and fit one of those if the standard Jabsco hand pumper is too low tech for you?

read all my replies and you will see the simple twist 'n lock hand pump Jabsco is very much an option, especially as Japanes ones don't play my kind of music ( handels water music?0

Jabsco lite. We have had one on our training boat for the last year its had probably 5 years use in a year, been perfect and as pointed out earlier MUCH easier to clean (i have a bad case of OCD around loos) I do hope it does not go wrong tomorrow after this post!
