Hi all,

Small update.

I have the system all up and running with the aquatec pump and a 12L water accumulator with a pressure regulator (Chris's coffee).

I figured out a way solve the two issues with the water tank:

1- not able to know when water runs out:
I installed a water level float sensor that has an LED warning and water is below designed level. I attached the probe at the depth I want (drilled a hole at the top and sealed it with the wire probe.


I put the LED and the switch to turn it off in a candle vase for cosmetic reasons.



2- issue with the drain of the water tank not low enough to utilize all the water in the tank. This is simple, I put a 3/4-1/2 fitting with a 1/2 to push connect tube fitting from the inside of the tank and attached a small tube bent downward so it touches the button of the tank. This way all the water can be sucked by the pump. I've also put a small strainer in the tube just in case some sediments got into the tank.

Are you sure you want to go that low in the tank? If air gets into the espresso machine it can be hard to get out, maybe? Slayers have a bleed group feature and I figure that's why?

The pump is self-priming in case it sucked air. Also the alarm I installed at high enough water level.

So, I'm rethinking my configuration and moving the water reservoir to an area with more room, specifically I have 17" x 22" x 29"h and figured I should just buy the biggest reservoir I can find. I've found this 25 gallon tank with a bulkhead (16" x 16" x 27"):

But I figured I'd ask if anyone knew of other resources that might have even larger tanks that might fit the available space. Probably unlikely and I'm basically filling most of the space.

This is the 6 gallon tank I've already purchased:

The only difference I can see is the material, polyethylene vs polypropylene, but they are both food safe as far as I know.
Thanks

Just factor in ease of cleaning. Also as I recall shipping on the larger tanks was much higher than expected. Enough so I didn't go larger.

So having read through this I have a question : why not just use a flow jet with a 5gallon plant spring and call it a day with some sort of a disposal container?

I get doing this limits customizability but for simplify sake ?

FloJet now makes some decent products. In the past their solutions would cycle on and off way too much. I am not sure what you mean by a "plant spring"

Spell check... Poland spring 5gallon with flojet or any recommended pump. Like the You I'm trying to find a carefree simple and portable or location agnostic solution not to worry about testing, being tied down to a specific location etc.... I feel this would offer flexibility of using a distilled with tww or Poland spring. I know this discussion is similar but seems like there's a lot of concentration on more detailed mixing, some more robust pumps which I'm confused about.

The reason I did this is I wanted 96% certainty on my water. If Poland gives you water that works for you then you have that option. 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.
