You can take your machine to your parent's house for the holidays or for that matter anywhere at anytime it only takes less than a minute to disconnect. You can't do that with the direct connect system, it has to be connected to a water source with pressure, it won't draw water from a tank.
I've heard conflicting answers to this question: Do all espresso machines that have inline plumbing require a water source with pressure? Is this because of the pressure regulator and is it always required?
For those who are really paranoid, and a little handy, you could wire a solenoid valve to the power switch. Machine off = water off.
A lot of CGs leave their machines on 24/7. You could hook the solenoid to the brew switch, but that would only give it a very short time to refill.
I can't handle espresso right away in the morning, so a timer is unnecessary for me. By the time I've taken a shower and dressed, the machine is plenty hot. I agree that if you don't leave your machine on 24/7, your solution would eliminate the consequences of a failure (and no risk of a failure while you're away).
This reminds me of another offline debate: Will you consume more electricity bringing an E61 type machine up to full temperature more than once in a day than you otherwise would by leaving it on 24/7? I'm a little skeptical, but it could be true. It takes a good amount of energy to bring 9 pounds of brass from room temperature to 200F+. Any thermal dynamics experts out there who can settle the question?

Ambient temperature would probably be a major factor in the calculation?
I would think that each manufacturer would be able shed some light on this, as I can't imagine a manufacturer not having a tech dept. This sort of information is normally given in the form of 1 start up equals x amount of running hours.

I have tried to email you a couple of times and the note is always bounced back to me so I hope that you will get this.
I have purchased the float kit from Chris and will install it on my Giotto soon but I would like to know if there are any potential problems you would like to address. Did you install on the right or left of the water reservoir? Are the hoses any concern?
If possible, could you email me a picture of your install? It would help me considerably.

Sorry about the email address - it was wrong in my profile (now fixed).
I drilled the hole approx. 2.5" down on the left side. Tighten the float so that it moves straght up and down. You do have make sure the water hoses inside the tank are clear of the float action. I keep them close by on the left side.
For safety, I turn off the valve when I'm away from the house. I haven't had any problems, but just want to be safe.

I'm a tiny bit concerned about a float system with no drain. More than once I've had a toilet float stick and the water runs and runs. No problem, because the water goes into the overflow. If the same thing happens with your Giotto, the kitchen will be flooded.
A year later, using this float system and I wanted to weigh in with some actual experience.
I recently screwed up while cleaning my system and without realizing it lost a washer in the float hookup. So I had the expected disaster when I hooked everything up, and left it on when I left for work. The flow was so small that we have no damage, but we did get some wet carpet and a moderate amount of water to clean up. Perhaps a large glass or more worth of water. It was easy to shut down the system and when I figured out what happened, get a new washer.
The flow is low enough that a day with a leaky float valve resulted in a wet countertop, a wet spot on the carpet, and no permanent damage. The concern over failure is real. The concern over damage may be exaggerated for day to day issues, but probably not if we had been gone for a week long trip.
In my final installation (when we finish buying our new home), I intend to have the system setup where all surfaces are expected and designed for water exposure and will have a catch bucket installed under the hole in the counter. I'll also move the valve shutoff to a more convenient position so I can turn it on and off without opening the sink cupboard.
Use the info as you wish.
PS - I still like this solution as it is simple, elegant, and allows me to take the machine to a wedding or special event much more easily.

HI, I'm pretty new here-- a toddler geek, so to speak...Great topic, since I'm trying to decide how to plumb my Brewtus....
one thing I really like about the float kit--my machine comes with a function that turns off the machine if the water level gets too low....I hadn't figured out how to preserve that function with direct plumbing...(I'm on well water)
I think if I install the float properly I should be able to preserve the "auto off" function. Quite an expensive repair if I burn up the machine! And if I install the on/off valve in a handy position, it should become part of my routine to turn it on and off (I leave my machine on all the time).
I'm interested in any other comments, but from my reading here, I'm very seriously considering installing the float .Thanks for all the thoughtful input!

Update: I did a mental inventory of the plumbing this morning. Only the ice cube maker has no "exit strategy". Everything else (washer, dishwasher, sinks, toilets) has at least one exit (drain), failsafe (overflow), or both.
Yeah - I came home to that in Spring. It was raining in the basement and the floors are a wreck. I don't know why a solinoid on the water dispenser on the fridge would fail to the open position after it hadn't worked for 2 years...
That said - is there a difference between the direct connect kit and the float kit? I would love to direct connect the plumbing. I would like to find something for the drip tray too - my complaint with the giotto is the tiny drip tray.
