Everyone hates emptying the loo cassette, the fewer times the better I say, so why do we have to take up 2 litres of capacity with the initial charge of water?. When there are site loos, number 2s go there and the van loo is just used for 1s overnight, even when there are no facilities on rallies/CLs there is usually a good quantity of filtered beer in the cassette before any solids drop in, so I for one have stopped adding water to the cassette and just add the chemical, as yet I have noticed no difference.
