No, Suvie is self-contained and does not require a special plumbing hook-up.
Suvie V1: Water is supplied to the appliance through the removable water reservoir that you fill before use. Then, after each meal, you empty the drain tray that is on the front of the Suvie appliance below the main door.
Suvie V2: Suvie will use only the amount of water necessary for each cook, and there is no need to drain the unit in between cooks.
The only hook-up needed is a standard electrical outlet. For maximum convenience during filling the water reservoir and emptying the drain tray, we recommend placing Suvie on the counter near your sink.
