Water flush...

Apologies if I am being really dumb here but I’m in the process of draining the water out of my van in preparation for winter frosts. I remember thinking about this last year but wasn’t a member of this forum then to ask for advice. I know to drain the water out of fresh and waste water tanks and leave taps in ‘on’ position, and reverse the pump switch thing in the cupboard under the passenger seat. But, what do people do about the toilet flush water? Do I just keep pressing the flush button and collect all the water in the toilet cassette? Not really sure what to do here as I think there’s quite a bit of h2o in there...or perhaps it doesn’t matter if there are no pipes involved? But there must be some sort of a pipe up there??? Hhhhmmmm? Help and advice please folks!

Just keep flushing it until empty. Bench type loos have a drain tube but the swivel bowl type don't.

I’ve not got a toilet flush tank but I can’t see the harm in flushing into the toilet cassette till it’s empty.
Sure someone will be along soon with a definitive answer.

Edit...as usual Paul beat me to it

On our Nuevo ES (2015) we have the usual swivel bowl; in the external locker in which sits the cassette, there is a drain bung (top, right, front). Pull out that rubber bung and the cistern tank will empty.

There's a thread of a few years ago which suggested substituting a medical catheter tap for the rubber bung. It helps because, with the bung removed, the water initially pours out of the locker, but when the cistern is almost empty the water pressure is low and so the water runs into the cassette compartment. The proposed tap, with a little bit of plastic tubing attached, directs all the water out of the locker.

But I can't see anything wrong with just continually depressing the flush button until the tank is empty - unless the flush pump gets too hot.

Will the tank be "empty" when pump stops?

This the catheter valve, click on the free sample and they will send one "for free"

That is handy, but there is no category in the drop down box for Motor Homer or Aquarium Keeper or Home Brewer

Patient/end user fits surely?

Thank you gentlemen...job done!,,

I have a dustpan handy to deflect the last of the water out of the locker and stop it going into the body.
