Long Overdue Thread .....

It was literally full to the brim because he hadn`t emptied it for several days since he got to the site so maybe that made the difference.

And I guess if you turn it upside down maybe.
I think when it comes to cassette empting, a bit of over-confidence can go a long way - quite literally! :LOL::poop::poop::cry::poop::oops::poop:o_O:poop:

interesting. so on the old cassette it is always up - so closed. Maybe meant to push it in before emptying?

Didn't someone here post about a problem with opening the flap and being 'annointed' by the contents due to pressure build up at altitude?

Our cassette is now some 7 years old, David. The push button mechanism operates as a Pressure Relief Valve [IIRC the instructions just say something like, ' ... to make emptying easier, push down the orange button' ...]. Roaming Rog had an unfortunate episode this year on his 'Italian Gadabout' where he was staying overnight at high altitude and couldn't open the cassette. He didn't know about the button either, tried to force the seal mechanism, and covered himself in glory [or something much more unpleasant! Probably will want to stick to custard on his rhubarb rather than risk the manure ... :D

I don't know the ins and outs of how these work, but the description of the grey rectangular pressure relief valve push mechanism includes the word "automatic", so you would think that would do something automatically to counter excess pressure?
There is a version of the same cassette that does not have an automatic version, but is manual (and it doesn't fit the same receptacle under the toilet, so the actual loo must be slightly different? Maybe that version of toilet has a manual pressure release control that activates the manual valve?). Maybe Roy's auto PRV is jammed like my old one is? Or he has a manual PRV loo and didn't push/pull/press a hidden control first?


There is a current thread on funless where someone bought the wrong relief valve version (auto instead of manual) and it didn't fit. His fix was to cut a hole so it slid in. Possibly returning to supplier for the right one may have been a better idea?

As I understand it, the yellow button is different and is purely a way to allow air to enter the top of the cassette as you are tipping the contents to avoid the glugging and splashback effect? (Similar effect to when pouring fruit juice with a small opening and tipping it too fast, or tinned milk - where you make a second top hole for air to come in and replace the fluid)
 
Our cassette is 16 years old now and still works perfectly.

All i ever done is to keep it meticulously clean and i`ve change the main lip seal 3 times after it developed a little dribble.
