Winter water drain down on 2019 Bourton

Advice on water drain down for winter storage please, apart from the usual drain downs  as per manual , has anyone been able to use the Floe system , or by applying as small air pressure to the shower hose?. I did managed to fit a Floe drain system to one vehicle , but very little room on our present vehicle for extra plumbing.

Just fitted a floe 636 to our Neuvo. It did the job perfectly. Not this year but hopefully next autumn/winter we will get out more frequently 3/4 times a month and this is where this system will come into it's own with an easy drain down each time.

I fitted the floe in the Elddis 115 some years ago  it worked very well but on the Bourton I haven’t got the space or access to the system due to the leisure battery and the EC700 unit being in very close proximity
