I am looking to add a 2 stage filter to my brewing system for filtering the beer post fermentation. Like the one in this thread
. I have a few questions for those that use a system like this.
1. What's the purpose/point of the purge button on the filter housing? There are filter housings that come with or with out this. Any reason to go for one with the purge button vs one with out?
2. I've seen a few setups with these filter housings where people have the filter housing installed upside down. What's the benefit of upside down vs right way up?
3. Gravity vs CO2. I know the setup in the link uses CO2 to push the beer through, but can you use gravity to do this? Ideally I want to use CO2, but that depends on me being able to pressurize the fermentor.
Any advise would be much appreciated.
