Your new coffee machine will require a water connection to be put into operation. Therefore, it is necessary to have a place created for this purpose to connect the water inlet and the waste. This can be easily solved in both cases with the appropriate branch piece.

Don't forget that you should always consider installing a water filter before your coffee maker. This will ensure three things: great tasting coffee without defects caused by inappropriate water composition, a hassle-free warranty and a long life for the coffee maker . Filtration is an investment that will increase the purchase budget for the coffee maker, but it is absolutely worth it.

Where to place a coffee machine with a water connection?
You are probably right that it should be near the water and waste connection . The ideal is of course the kitchen and the location of the coffee machine near the sink. Alternatively, for example, during a planned renovation, have the water distribution for the coffee machine built where you would like it. Then Please note that there will be 2 hoses leading from the coffee machine. (inlet and outlet). The most common method is to make a small round hole in the table top or kitchen counter under the coffee machine. It is also possible to run the line between the table top and the wall behind the coffee machine, just be careful not to pinch the hoses.
Another need of the coffee machine is power. So think about a location that also has an electrical outlet nearby . This can of course also be solved by using extension cords, if you have a suitable location for them so that they do not interfere with the view and are protected from moisture and dirt, as their safety is threatened by splashes of water, steam and contamination with coffee grounds in the coffee machine.
