Plumbed-in bean-to-cup coffee machines
A mains water connection and waste drainage mean less refilling and emptying. Which Coffee Format models have them and what to prepare on site.

Why plumb in a coffee machine?
A 2–4 L tank has to be refilled several times a day once you serve more than a few dozen cups. A mains water connection removes that job, and a waste drainage connection removes drip-tray emptying as well. The milk system still needs cleaning every day.
Which Coffee Format models can be plumbed in
| Model | Mains water | Waste drainage | Tank |
|---|---|---|---|
| FIT W4L | yes, via pressure reducer | not specified | 4 L |
| ATLAS | yes | not specified | 2 L or 8 L |
| BREAK | yes | yes | 2 L or 8 L |
| DUKE | yes | yes | 2 L or 8 L |
| DEMY | yes | yes | 4 L |
| ZONE | yes | yes | 4 L |
| GROW | yes | yes | M: none, W6LM: 6 L |
| DOUBLE | yes | yes | 4 L |
SEED and BLOOM are tank-fed only. ATLAS, BREAK and DUKE come with a 1.5 m braided hose (G3/4″ to G3/8″).
What to prepare on site
- A water valve within reach of the hose, with a 3/4″ thread, ideally a dedicated one so the machine can be isolated.
- A drain (trap) close to the machine, if the model has a drainage connection.
- A power socket without an extension lead. Larger models draw up to 2,900 W.
- A water filter matched to the water hardness. Without one, limescale builds up faster in the boiler and thermoblocks.
- A stable worktop with room above the machine to refill the bean hopper.
