“The reason you need 1LIMIT for your family”
‘1LIMIT’ induces users to save water in each time of use. ‘1LIMIT’ fills up one liter of water in it when the lever is closed. If you lower the lever, you can use that one liter of water contained in it. If you want to use it additionally, you have to wait again after closing the lever. This way of using may let you know the amount of water you use visually. If a family with four members uses ‘1LIMIT’ for a day, they can save 40 liters of water, and this is up to 14,600 liters per year. Thus, if you use ‘1LIMIT’, you can save tap water that may be wasted unconsciously.
