I see what you're saying but going full pressure will cost me money I don't have at the moment and I want to build something now. When I do have money it will be for upgrading Loki 2. Also more flips on low pressure and fittings are cheaper/more available. Also the dump valve is on the buffer tank, plan to put a push fit adapter in it and pipe it to the rear:


How do I go about putting in an uptube/antisiphon tube? Tap a thread in the bottom of the pin valve, adapter and tubing?
