Arriving on site: Campervan toilet cassettes

[@travelcampervansandmore]

When does one knows when the cassette is full? Does the flush button lights up?

Normally next to the flush button is a red led, this lights up to let you know, I think its when y has about another two litres to go until totally full, I would empty it before it got totally full, I have always done this never had a problem Inside the cassette is a little float that has a magnet then rises with the level of the cassette, it has another magnet on the outside that sort of reds the level of the inside magnet hope this helps
