The dark bowels of a toilet cassette

[Glas Robin]

Anyone got a picture of the insides of a Thetford cassette?

I’m trying to understand what the baffles and internal chamber looks like to improve the efficiency of my emptying technique - instead of aimlessly twisting this way and that.

I’ve done obvious Google image searches as well as looking at parts diagrams with no luck.

Thought I’d ask before I dismantle one at some point.

I think there was a YouTube video showing a cut in half cassette, I'm sure it was to show the blade closing mechanism

 

[David and Sally]

No. But in 30+ years of twisting and twiddling I have never even worried about what it looks like inside

 

[Realist]

Emptying takes seconds, do you press the button to get air into the cassette while emptying?

 

[rb62]

Open the flap shine a torch in if your that desperate!

Not sure if one of my old threads might help..

Servicing The C200 Cassette - Seal Replacement

The cassette was starting to get a bit pongy, even after minimal use, so time to replace the seal and service the O rings at the the same time. Thought I'd post a few pictures in case it's of help to anyone else. Thoroughly flushed and rinsed with lots of bleach and water, followed by a good...

Open the flap and poke your mobile phone in to take a dirty video.

I had occasion to change the seal on our cassette , I’d always prided myself that the inside of the cassette was spotlessly clean ………… i was VERY wrong , it was filthy with crud and slime in hidden crevices ( to the naked eye ) , like a new pin now mind !

 

[Manic]

No baffles but the bend on the emptying spout can be a problem I have been known to remove that for easier flow.

Yippee a toilet thread.

Curiously enough, I've just been exploring the innards of our C200.
As above, there are loads of videos on You Tube on servicing etc.
About 3 or 4 times a year, I half fill ours with warm water and some bio washing powder. Leave it to stand on its base for 20min, then turn it onto its side for 20, onto its top for 20 then its other side etc.
Remove the slide, the two slide retaining clips spring off, remove the eight stainless screws and the seal and its retainer lift out.
This allows access to get hand and lower arm inside with a green plastic scourer. You will be able to feel the exit and all the gubbins. Refit the seal etc.

Incidentally, rather than using the pressure release button when emptying, I remove the slide all together and open the sliding arm. This makes emptying more thorough.

P.S. don't forget to wash your hands before the congratulatory tea & biscuits.

we use bio liquid all the time in place of the smelly blue stuff keeps the cassette clean

It would be fun watching you do that when it's full to the brim.

That's when I put my arm in a sling before approaching the CDP and hope for some kind soul to take pity on me!!

How do you identify which version of the Putin Box you have? There's no identifying marks on it, just some serial number.

Oh and I just a look inside. Nasty. Needs some industrial caustic soda, a Black and decker, and an NBC suit.

As an aside, Jan bought recently some loo paper from Aldi that is only 100mm square. Apart from the lack of 'wriggle room' would it be better for the cassette?

 

[Lenny HB]

Remove the slide, the two slide retaining clips spring off, remove the eight stainless screws and the seal and its retainer lift out.

On the later C260, C400 etc., no screws just just swivel mechanism holder about 45° and it lifts out.

Citric acid & white wine vinegar both work well.

Always stock up abroad for the cassette as their sheet size is smaller. Used to be the Continental size in Lidl but now UK size.

Even at home, if you haven't eaten it, it goes into a bin.

Flashback to squares of Izal - thanks for reminding me

Cheers Lenny,

Got me on that one don't think that's a Thetford may be a Dometic. Although the knobs & cap look like Thetford only seen Thetford with yellow/green or orange bits.

What does that tell us about the size of a (bog) standard British a**e?

Yippee a toilet thread.

Good to know that you're easily pleased!

Cheers Lenny,

Got me on that one, never seen one with blue cap & knobs looks like a Thetford but only seen Thetford with yellow/green or orange bits.

It's got Thetford written on it!
I have gone onto Thetford website, and it seems to be a C220 on a C223-S khazi, that flushes electrically from the main water tank.

Disgusting Admission.
Just found that there is a float thing that needs to be cleaned. Never looked at it before, didn't know it was there and obv never cleaned it before. Looked at it and it is uber-vile.
