I almost went with a 5 gallon solution but the availability of tubes to use were limited. Cafewerks now sells one I think. If you can find good water in a 5 gallon size and a reliable pump go for it and post it here. Just not the Flowjet 5000. You need to make sure it's not going to cycle on each shot. That's why there is an accumulator in the system I use.
Interesting, is Poland spring not widely available in AZ? LM highly recommends bottled and after a lot of discussions here and with LM staff it sounds like that's the more simple approach although I hate the idea of buying water vs using tap. In any case Clive coffee has a video for this setup and suggests no need for accumulator unless using multiple devices so are they just going for simple as can be? Accumulator I suspect would give me close to or exactly what line pressure would be for duration of use? It's a fairly sensible solution and I'm sure helps avoid unnecessary hiccups. Sounds like I should account for some check/shutoff valves at every junction to easily service the parts but does that not impact pressure somewhere along the way? I'm imagining flojet/pump to check valve into accumulator to check valve to some length of line to shutoff then to machine? The shutoff there would allow water to remain in line to machine but allow disconnect from the rest of system. Check valves will prevent flow back but does one work better than the other (check vs shut)?

I don't know if Poland Spring water is available here. What I do know is that it only takes me about seven minutes to make enough water to last 2 1/2 months. If my hooligan cats aren't around it's probably only four minutes. To me that consistency and ease makes it an easy decision. If you want to chat through your choices send me your contact information in a private message.

Hooligan supervision of the water changing process. I am careful to make sure they (brother wasn't here yet) stay away from the tank and that takes me longer. Otherwise it works well.

As to using a 5 gallon container - Yes do it if you can find acceptable water.
You may still need an accumulator.
Get this adapter tube from Caffewerks with a built in check valve. They have other parts that may be of interest to you, including a 7 gallon tank.

Haha priceless, quality assurance at its best can't be mad there.

Yes Poland spring is widely available in 5 gal and I was considering just getting the whole setup from caffewerks which includes the pump accumulator check valve and tubing. In terms of pressure at the machine no issues right? Thinking if LM introduced line preinfusion it would be a nice to have with plumb.
