I don't really follow. I have a cut off valve between the water container and the pump, so I just close that, take the container to refill, then put it back and open the valve. Unless I'm misunderstanding something? The instructions that came with the pump say it only primes if pressure is relieved from the outlet port.

Yeah, I tried the same thing and you might be OK, but you'll probably end up with a little air in the line after the bottle swap which was a bit of a chore for me to purge/prime each and every time water carboys were swapped. That's what led me to a separate water container with a large lid to be able to just pour water into...works perfectly as long as I don't forget and let the water level drop below the outlet (seldom to never as its a 10-gallon container).

Gotcha, I'll definitely keep an eye on it. I'm still trying to figure out a good method to cap it. Might just thread a fitting through the screw on cap I already have and run more rigid 3/8" tube down to the bottom of the jug.

Why not install an outlet with 3/8 JG. Or ideas from here.

I even tried 2 carboys in parallel. Then added one way valves feeding to the Slayer (and formerly the LI) to no avail; always ended up with air introduced into the lines when swapping bottles.

Another question for you guys, what pressure do you run your setup at?

I use 3 bar. @sopressomon is 2-2.5. May depend on your machine.

I wanted to share the piece parts the I subbed out to save a little cash on my setup, it's been humming along about a month now without issue with an old Vivaldi S1 V1 I picked up. Here they are (FYI these are affiliate links):

pump - https://amzn.to/3v0Reoh - reading around folks said this one was quieter. with the large-ish accumulator tank it rarely comes on and is super quiet.
pressure regulator - https://amzn.to/3wZFSTk - definitely cheap-o compared to the Chris Coffee one but it seems to have done the job along with the gauge below
pressure gauge - https://amzn.to/3n0yoej
accumulator tank - https://amzn.to/3ec1xPM - same brand as the RO system I have but still works nicely.
water jug - just picked up at the grocery store. The 3 gallon size fits nicely under my RO spigot in the sink for refills (which is sooo nice to only fill every 3 gallons!). I tucked it all away pretty much just like @CarefreeBuzzBuzz did, working great!
