BT dunny - a clean drop

Now that we have taken to the road with the van - we are becoming educated - For the dunny we bought some el cheapo paper towel, which we place in the bowl on top of the valve (fits perfectly) before the "bombing run". This stops any need to clean down the valve ( I learned fast, cause the cook said, you dropped it you clean it ).

I also noticed that the toilet flap valve should swing in under the hole - with the last movement of the flap being upward to seal the cassette off.( this is a water tight seal)

Initially it did this - but after I emptied the cassette I saw that one of the wires had been jammed by the female groove on top of the cassette, I moved it out of the way only to find that it would not seal ..........swing across - but wouldn't "click" up and seal.

Inspection revealed that a second wire had been interfering with the click and seal operation.

So check your dunny - rotate the flusher clockwise - which should close the valve over the hole, and then there should be a resistance and an audible clunk as the valve moves up and seals.

Probably the best way is to tip in a bit of water, which should pool ontop of the valve - if it disappears into the cassette then your valve isn't sealing.
