Thetford blade “welded” shut

This MH has been standing idle for an unknown amount of time due to last owners ill health.
Our friends have filled the bowl and now cannot open the blade. I would imagine it is stuck due to lack of use and not being lubricated.
We may have to ladle out the contents I suppose but suggestions please for loosening the blade
Thanks

 

Silicone spray is what I'd try

 

Just press down on it around it's edge, beware of splashback though !
Failing that, pull the cassette out and undo the screws that hold the seal in place, it'll come away then.

 

Seals can stick, hence why when left for a while it's always better to leave the flap open a little

 

Absolutely,

 

Poo glue is like Uhu, a good whack with a blue shoe is needed to unscrew.

 

sticks like shit to a ..... er thetford

use an old blunt knife to break the seal. dont force the lever as it will break the plastic blade

 

We’ve got cassette put and year old poo inside and welded to seal.
Done a clean up best we could here and now works ok
I suggested to friends to get a new casssette (wife not seen condition) husband told me he’s going to clean up at home

 

If empty, can they stick Ina bath of warm water? Leave for a few hours of even overnight.

 

Rubber seal has stuck to plastic blade.
Removal of seal may be the only solution and fit a new seal at the same time as there's a chance the lip on the old one may tear on removing from blade.
I doubt it will ever seal properly again anyway even if it doesn't tear.

 

Himself, or the cassette?

 

Am i too late to suggest gloves then ?

 

OOhhhh oooooh oooooh

The wife says just drop the whole casette into the bath or similar in diluted milton (or wilkinsons cheap version of milton)

 

Don't use the ladle for soup is my only additional comment.

 

Noo - you'll have the bowl contents to clean out of base if you do that. Use something (a stick?) to press hard on the centre of the blade. You'll feel it free off.

 

Big plunger and WD40

 

Struggling to understand how they could fill the thing if the blade was stuck. But in any event they should still be able to empty it through the spout. Or have I misunderstood the problem?

 

Yes. Bowl above blade full. The OP didn’t say what with!

 

Yes you’ve misunderstood.....
The cassette did have some contents but that was over a year old from previous owner .

The toilet bowl was filled overnight with combination of wee and flush water by our friends.
Then in morning I was asked how to get it out of the bowl and into cassette because their lever wouldn’t work. That was when I discovered their blade stuck to the seal.
The funny thing was, when I asked the husband to press down on blade as per one of the earlier suggestions in this thread. What put my hand in there! It’s only your own wee says me. I even made him squeeze out the paper and put that in bin lol.
Then when enough of a gap had been formed, the liquid drained into cassette and we were able to remove the cassette.
Then he poked at the dried brown stuff on the blade with his finger. Don’t do that. ! I said
Why?
It’s dried on poo. !
You should have seen his face.

 

poo is only part digested food. people are so squeamish about it, but you happily wipe your own bum daily when its fresh and warm
