what a set up!I have built a wooden cart from some old shelving for my conical, so its about 3 feet above the floor. This allows me to gravity transfer from the small outlet tap so no need to transfer under pressure.
I also capture co2 whilst fermenting directly into a keg (previously used a fermenting bucket to collect).
Blow off tube connected to liquid out post on keg. Gas in post vented to a plastic pot. so only co2 is sucked back when cold crashing or bottling.
When kegging. I disconnect the blow off from the liquid in post & connect it to the gas port on the keg. The gas port is now connected to the top of the conical.
Gravity fill the keg from the small outlet tap on the bottom of the conical into the liquid post on the keg. As beer enters the keg co2 is now pushed out & back into the top of the conical. This results in a totally closed transfer system eliminating any o2 from entering the system.

The loop of silicon tube has a small amount of starsan in it which acts as an airlock.
