Ok mystery solved....back at my workshop on the bench with my magnifying desk light...I could see that a bit of the original seal was still in there...after removing it with a tiny screwdriver...the new (second new) seal fit right in...i will go back and refit as soon as I have the energy (possibly tomorrow)
Only hope that I haven’t damaged the back of the centrifugal impeller trying to force it on 😳

My advice to everyone in boat land...what the eyes can’t see, the hands can’t fix

When do boats stop going wrong ?
It’s nearly midnight and I have noticed a leak coming from the pump assembly at the base of my Jabsco quiet flush electric toilet
I never get to my backlog of jobs because there is ALWAYS a newer more urgent job
They generally stop going wrong, for you, once you sell them

There is an etiquette of not flushing after about 11 pm....you can extend when next to yotties because they don’t stop talking till after 1 am...longer if one of them picks up a guitar. But the truth is if the bowl is so full that I start getting splashes on my legs then I’m flushing (or at least draining the piss which is just as noisy)...and if a motorboat keeps me up all night with their air conditioner pouring a constant stream of water into the sea...then I’m getting up at 4 am just to flush AND wash my hands

That’s your problem you see us northerners , are well blessed so if there is any water in the bowl our end gets wet , so we have to flush continually .

Never had that problem in 14 years of Tecma. I always set the water usage potentiometer to maximum water.
Bruce, there is no tp downstream of a Tecma, in the pipe to the tank. One it leaves the Tecma unit, everything is heavily macerated into a blended consistent fluid/slurry and the tp doesn't exist as tp any more.
I found my problem. My unit had a anti syphon valve in the toilet outlet for holding tanks higher then the toilet / toilet below sealevel. A sort of cross shaped duckbill valve. If anything is too close to the mascerator on start up it takes a couple big slices first before spinning up and becoming efficient and then packs the valve. That rubber valve is much stiffer than those of Sealand Vacuflush and its housing a greater diameter than the outflow pipes so a bit of a collection choke point. I have removed that valve now. Were it neccessary I would probably go with the sealand duckbill being softer and even if it only lasts a year before service instead if 10 its at an easy enough place to reach and service so not too much pain there.

EDIT mine is the nano version as its on a plynth. Personally I think the problem is down to the mascerator being too close to the business end of the U.

I removed the Jabsco electric conversion which had lasted something like 2 or 3 years since previously serviced before it performance reduced (which was disappointing).
In its place I installed a complete Jabsco manual pump (in July 2020) at a cost not greatly more than the service kit for the electric pump. As a result the noise output is very much lower decibels when the pump is in use and of course the bonus of no electrical power required. So far the manual pump has showed no sign of any issues.

On a separate but related note I rebuilt a Jabsco macerator pump last year (the type used to pump the waste out to sea) . The kit was at a worthwhile cost saving compared to a complete new pump. The original electrical motor was fine - all of the pump components new.
An aftermarket macerator pump had lasted under 2 years before the electric motor became faulty so had proven to be poor quality. So Jabsco not the best but not the worst .

Bruce, Tecma’s nano version (the one with the small bowl and designed to go on a plinth) is awful. It just doesn’t flush well. Although I think their mainstream unit is excellent and I just specced those for my new boat build, that nano version is always a very poor performer imho.
