Thank you Geoff, very clear video. I ordered the parts you suggested and tackled the job today. My C200 differed slightly to yours and i was able to take the blade out, clean it and refit it easily. The vehicle is 22 years old and I don't think the cartridge has ever been stripped and cleaned. Even in the 12 years I've had it I wouldn't have thought of doing it if it hadn't started leaking, and i can't afford a new cassette!! Thanks again, I wouldn't have had a clue without your video. 👍👍
Thank you. This was very helping when the blade became detached from the sealing disc whilst on our holiday. A dirty job, but someone has to do it. Thanks again.
Excellent informative video, notwithstanding the obvious error of not doing the vent and buttons whilst the blade is out of the way and access is better. One observation; Vaseline is a petroleum based product and should not be used with rubber seals as it will damage them. A silicone based lubricant should be used.
I wish I'd watched this before doing mine, as I had to relocate the arm. I cleaned mine with Thetford cassette cleaner, to get rid of scale, the day before. That really helped. And it doesn't leak anymore!
Totally agree. So many fix it videos on CZcams, where too much time is spent on 'like', 'subscribe' and 'follow'. And a lot of other nonsense. Sometimes half the video is wasted on useless information.
Very brave man !!!! On a serious note , very good video . It’s nice to know the cassette can be cleaned and maintained in this way . I got the fresh up kit but mainly to have a 2nd cassette as a spare and fancied a new toilet seat as it was a second hand van we got lol . I will be using this video as a reference point to maintain the two cassettes 👍🏻👍🏻👍🏻
Thanks for taking the time and doing not a bad video really, I think that it was covered in Cr*p added to the entertainment value, and it showed how messy a job it could be, I would empty and wash it thoroughly if I was doing my own though, and wear short sleeves. Not seen the other vid mentioned, but Wickersham is well boring to watch.
Would just like to take the time to say massive thanks for this video . Very helpful indeed . I need to know how to fit the floater part tho , when I was cleaning mine out today I noticed the floater had come away and was floating in the water..... Thanks again for your superb videos 👍
Like one other poster, I have doubts about the use of Vaseline on rubber components as it is mineral-based.Think it would be better to use silcon-based lubrication.
I wouldn't argue with you Alan, silicone grease much better. I didn't have any to hand at the time, and despite the dire warnings the Vaseline has been ok, but definitely best to use the proper stuff.
Thank you for this video. It explanes very much to me. I should have seen this a week earlier because I had to invent all you showed by myself. Indeed with some parts you must have the abillity of a gynecolist >
me i would have washed it well before dismantling, and i would have used tank cleaner for 24 hours before hand, i use silicon spray makes life better and doesnt attack any rubber seals
Thanks for showing us how to refurb the cassette and the difficultys involved,but i have to say that i think that i would jet wash it before tackling this, and apart from that i would never let it get in that condition in the first place
+Michael Mace When you have changed as many babies nappies as I have, a little bit of sh!t holds no fears. So long as your hands are washed thoroughly afterwards, no problem.
Great video Geoff. I dont need to do this as yet but it will be of use so I have downloaded it. Can I just make a small suggestion and fit the lip seal last as your still having to put you hands inside the tank to replace the other parts. Many thanks
thanks for the video, we wanted refubrish waste tank after buy older camper as well, but when i seen your video, how dirty it i bought new one. Thetford now sell new tank (with wheels and holder, this i didnt have in old one) and Seat & Cover and two toilet care products in one box for nice price - at least in my country, when i buy here all spare parts, i will pay almost half price of the set from Thetford - i got it for 110 gbp. so for 60 gbp i will not do this hard work. but your video really helped in this desicion....
Good, but I think tipping the tank on it's side makes for easier reaching inside (saves trying to twist your hands all over the place). As for all the people giving it large about dirty tanks and touching it! Calm down dears, it's only shite and we all do it! I operate an effluent removal tank mounted on the back of a pick up. You wanna see some of the mess I've had to deal with. I think some of you would be in hospital getting a liver transplant after you vomited yours up, lol. Hands & equipment wash. But You can get gloves that go up to your bicep if you're inclined to get them.
Fine video. Do you know if its possible to remove the guide plate for the hole disc. That's all got scale on too. One thing I would say is when doing this job. So long as you flush it out properly all the shite comes out so not really a dirty job.
Superb video. Straight forward to tackle these jobs when you have information like this. Do you know if the vent should leak? I have noticed mine does when I am cleaning it out. Many thanks
I'm in THAT part of CZcams again. Geoff, I sincerely hope that you binned that jumper after this. Whether or not you've changed countless babies' nappies, you're still running the risk of coming into contact with e.coli, gastroenteritis and any number of other infections.
Ah well, still alive 3 years later anyway. Everything was washed afterwards, including me, and the only poo in there belonged to me and my wife. My mum said "We all eat a peck of dirt before we die" [Definition: One peck = 2 dry gallons]
Hi Basil, only just spotted your comment. No I haven't tried replacing the float arm, although I do have a couple of tanks where the light has stopped working, so next time I need to replace some seals I'll look into it.
Are you joking? Before starting any kind of repair and applying spare parts, i would give this tank a complete and intense hot water cleanup from outside AND inside using all kinds of active foam and brushes. I cannot believe you touching this mess all over and already applying spareparts to a sticky stinking uncleaned tank.
I agree with you EPNER. Sure, it might be his own crap, but I doubt he'd go running about in a shower of it. Seriously, it just takes 30 mins to put some near boiling water to kill off any pathogens and nasty stuff that might be lurking in there, and throw a little bit of bleach and/or limescale remover. Just done that with mine and inside and out, it looks and smells almost new.
I think it just unclips. From time to time Thetford sell what they call a refresh kit, which is a new tank, new seat and lid and some cleaning fluids in a pack - about £80 I think, so the seat and lid must be quite easy to remove.
No thereford site doesn't say much at all.just gives a part list which is confusing enough. Mines the lower beige in in this photo. forum.karawaning.pl/uploads/monthly_11_2013/post-8228-0-11704200-1384969985.jpg
+Richard Poll those are both different from mine but at a guess I would say the lower one is an older model because the top one looks to have the pressure release valve the same as mine, and that is definitely the same as on current models. Also the colour of the top one is closer to the colour of current production.
Yes its very fiddly, you can't see what you are doing and have to try and do it by feel. It seems a bit hit and miss - you just keep trying and suddenly it will snap into place. If its any consolation it seems to get easier the more times you do it!
Dont Do It : no, the seal is not a simple o-ring (at least not on mine) it doesn't have a round cross-section. I tried an ordinary o-ring but it still leaked.
Yes I know its chamfered (looks like a seal from a motorcycle brake calliper piston) I repaired mine with 1 O ring and a flat rubber washer. flat washer placed on shaft 1st O ring beneath to make the seal with main cassette body. The blade is a piece of preverbial to put back in place if it slips. A good motor factors usually have a selection box of both, cost about 50p each.
It should be possible to re-fix it but it is a fiddly and frustrating job because you have to just do it by feel. I think there are some other CZcams videos which show the inside of a cut-open cassette.
A volte il magnete cade dal braccio galleggiante, quindi il sensore di livello non funziona. Non credo si possa fare molto al riguardo, ma è facile vedere quando il serbatoio è pieno.
Well, not so much that I forgot but that I have never needed to do that with any of my cassettes. My oldest is over 15 years old and the spout seal has never given me a problem.
Hiya Geoff just watched this video but have just got to say that putting petrolium jelly onto rubber seals is a real big NO-NO there is not much els that makes them go hard and brittle as fast BTW I can tell you're not a mechanical engineer
It was all I had at the time! I have to say though that the seals in question are still working ok. Of course there are an awful lot of different rubber formulations for seals for different applications so maybe I struck lucky!
Hi Barbara, no it's not a job that is particularly appealing, but it is at least my own crap! I wouldn't want to have to work on public sewer systems, but thank goodness some people don't mind doing it or we'd be in a terrible mess.
No harm to you but if my tank was as rotten as yours I would have binned it and bought a new one. I would certainly never put a video up showing everyone what a dirtbag I am. Gross, no excuse
Thanks for that :-) the refurbished tank is still working fine, every bit as good as the other three I have. I have the satisfaction of knowing that I have saved a good chunk of cash, and kept a large piece of plastic out of landfill and the environment. It's difficult to see how a large tank of sh1t can be anything BUT gross! The dirt on the outside was just dirt BTW.
True! It's only when dealing directly with our own waste that we can appreciate the unsung heroes who spend their whole lives unblocking sewers, fixing sewage pumps and repairing cess-pits...

Have you thought about giving it a wash , before you start?
thanks for the great vid! Just had to change a broken automatic valve on our cassette and had no idea how to get the old one out.
Would just like to take the time to say massive thanks for this video .
Very helpful indeed .
I need to know how to fit the floater part tho , when I was cleaning mine out today I noticed the floater had come away and was floating in the water.....
Thanks again for your superb videos 👍
This is a very helpful video for a very unpleasant job.
I'm off to wash my hands now
Good informative video. I would suggest shorter sleeves and longer gloves though. 🤢🤮😂

I wouldn't argue with you Alan, silicone grease much better. I didn't have any to hand at the time, and despite the dire warnings the Vaseline has been ok, but definitely best to use the proper stuff.
Vaseline will destroy natural rubber, but should be ok to use on synthetic rubbers. Sure thetford use synthetic rubbers on their builds. :)

+Michael Mace When you have changed as many babies nappies as I have, a little bit of sh!t holds no fears. So long as your hands are washed thoroughly afterwards, no problem.
Jet washing would throw the muck and stuff into the air in a fine aerosol which you would inhale. Just wipe it over like Geoff. Much more hygienic!

Not sure. I'd say if it's not causing a problem with the operation it's best left alone!
Thank you for that
And thanks for the coffee in Gloucester
Excellent! thank you
that is the most gross tank I have ever seen, surely it should have been thoroughly cleaned before starting work?
Lol. It's only sh1t. Mostly mine! Don't be so squeamish 😉
A good clean of all the seals and applying silicon grease would have got this cassette up and running again
Charles Toogood sorry it wouldn't. I had already tried that without success. I found that the old seals were worn and distorted.
Can you buy the handle cover with the writing on and if so where from as I can't find any part no. Or info . 👍
Great video, helped a lot thanks
Vassalene, are you sure ,it has petroleum in it ,probably rot the seal
Great video though i would double glove for that one! Thanks for the info
Why not use a Gerni water blaster to clean the tank before you start working on it
Why doesn't one come up with a super cheap disposable cassette?! Make sense!
I wouldn't want to splash and spray it around and then breathe in the mist. Better to wipe it over with a rag and sanitiser
Superb video. Straight forward to tackle these jobs when you have information like this.
Do you know if the vent should leak? I have noticed mine does when I am cleaning it out. Many thanks
When the cassette is out of the toilet none of the vents or valves should leak. If one does then it is not sealing properly.
@@rampak1 cheers Geoff
I will inspect 👍
I'm in THAT part of CZcams again.

This is one you already owned? You didn't buy it off eBay or owt to refurbish?
Oh no, this was mine from new. I wouldn't buy a second hand toilet tank!
Are you joking? Before starting any kind of repair and applying spare parts, i would give this tank a complete and intense hot water cleanup from outside AND inside using all kinds of active foam and brushes. I cannot believe you touching this mess all over and already applying spareparts to a sticky stinking uncleaned tank.
Don't be so squeamish! It's our own muck and no more dirty than cleaning a baby's bottom. A thorough hand washing afterwards will remove any bugs. 😀
Whilst I agree with you, Geoff about not being squeamish, I think I would have used a clean cloth to wipe the cassette over at the end!
Not mine. I inherited some fossilised gunk from previous van owners LOVELY.
Dont Do It Eughh! I think I'd have ditched the tank for a new one, but I can tell you're more thrifty than me ☺
I agree with you EPNER. Sure, it might be his own crap, but I doubt he'd go running about in a shower of it.
Seriously, it just takes 30 mins to put some near boiling water to kill off any pathogens and nasty stuff that might be lurking in there, and throw a little bit of bleach and/or limescale remover.
Just done that with mine and inside and out, it looks and smells almost new.
How on earth did you get it so dirty?
It spent some time stored in the engine room of our narrowboat when it had a leaky exhaust, so most of the dirt is good clean diesel soot!
that was very interesting, thanks. Do you know how to rmove the toilet seat, as I would like to do a thorough clean on mine
I think it just unclips. From time to time Thetford sell what they call a refresh kit, which is a new tank, new seat and lid and some cleaning fluids in a pack - about £80 I think, so the seat and lid must be quite easy to remove.
I have seen those Geoff and I thought the job ought to be easy. Maybe I'm just not strong enough to pull the sides apart. Thanks for your help
It's pretty tough plastic - so maybe carefully levering at the sides might do it - don't hold me responsible if it does break though! :-)
No, I won't Geoff! Thanks
Any idea of where I can buy the refurb kit? Had a look on eBay uk but can't see a complete kit. I don't Mind getting my hands dirty lol
Hi Richard
I didn't buy the parts as a kit but got them from here:
www.bradtech.ltd.uk/products/Toilet_spares.html
Hope this helps
Hi, thanks for that. Any idea how I tell if my casette is the pre or post 2007? Seems to be a different kit for each
Richard Poll hmm not sure how to identify the two, maybe the Thetford site gives a way?
No thereford site doesn't say much at all.just gives a part list which is confusing enough. Mines the lower beige in in this photo. forum.karawaning.pl/uploads/monthly_11_2013/post-8228-0-11704200-1384969985.jpg

Seems to be tricky to fit the blade knob.

If its any consolation it seems to get easier the more times you do it!
Surely the blade opener only needs a new o ring rather than complete unit

Yes I know its chamfered (looks like a seal from a motorcycle brake calliper piston)

A good motor factors usually have a selection box of both, cost about 50p each.
Dont Do It Thanks for the tip! You're right about the pain of refitting the blade if it comes off.
Hi what’s the capacity of the tank ?
I think this model is 17 litres
Hi my blade has dropped off any idea how yo mend
It should be possible to re-fix it but it is a fiddly and frustrating job because you have to just do it by feel. I think there are some other CZcams videos which show the inside of a cut-open cassette.
