Our drinking water filtration systems are typically installed under the kitchen sink (WA3, WA7, WA9) or near the dishwasher or washing machine (WAV). To supply the entire house, a flow rate of approximately 10 liters per minute is temporarily required. This works with our industrial systems, but they are expensive. For the purest water, special pipes would need to be installed throughout the house. A better solution would be a combination of the WA7 in the kitchen and the WAV for the washing machine and dishwasher.
