I'm in the process of writing a "How-to" for the whole house wine filter setup.
I've tested this a few times with water and it seems to do fine with just gravity. When I tried with the vacuum pump, it created a lot of cavitation and seemed too harsh as it was sucking the wine through the filter housing. Gravity feed is a more relaxed and enjoyable experience for me.
I used a racking cane in the carboy and a bottle filling wand in the bottle. I do use the vacuum pump to charge the system and get the wine flowing but after that, it's just the valve in the bottle filling wand to start and stop the flow.
As soon as I have a batch ready for bottling, I will take the videos and finish the tutorial.
