@Paul ... My best advise regarding the toilet is "Just harden up Princess and do it!!!!"
Nah not really... I have been in the Water and Waste Water industry for 40 years and have come across all sorts of "Toilet waste" new and OLD
ainkiller:
You never get seasoned but you do learn to put up with others sh!ite
(It might be sh!te to you..... But it's my Bread & Butter
)
A serious tip though is to put a few drops of eucalyptus oil in the flush water and run that through the system before doing anything else. Let it sit for a few hours, remove the cassette, drain it and hose it out.
The sight glass you mention, if inside the cassette storage area, is more than likely the flush tank level indicator. Dependent on toilet make and model the level indicator for the cassette will more than likely be inside the toilet area on the front area under the seat or on the flush button. Either will have a series of LED's or a red/green indicator (Don't let it get all red
).
A tip for emptying..... Don't let it get over full and follow the manufacturers instructions when emptying. ie: DO NOT press the air release button while tipping the cassette..... Do it once the outlet tube has lined up with the dump point drain
We have stopped using the toilet chemicals for the cassette and flush tank and have started using coles home brand nappisan (Now called Oxy Booster Laundry Soaker or similar) in the cassette and Eucalyptus Oil in the flush tank. The smell in the caravan is now more natural and sweet rather than smelling of chemical smells and it breaks down the contents just as good if not better!
After doing the original clean as mentioned above... Leave the cassette open and outside to dry and air for a day or so, then mix one capful of the laundry soaker in one litre of hot water to dissolve it, empty into cassette, shake and roll to the music of Elvis Presley
and let it soak for a few hours. Drain and flush then add some water with a few drops of eucalyptus oil, shake it and replace in van... "should" be no more brobs :encouragement:
