A: 1. To make the water evenly pass each filter to reach complete purification, the water should flow through the constant pressure at the base, thus, the water coming out is always less than that from the faucet. If the amount is much, it means the filter is out of order.
2. Each area has different water pressure. Even the water from the faucet is much, it doesn’t mean the water pressure is strong. By means of the constant pressure design, the low water pressure will come out less amount of water.
3. If the flowing amount is little, the first filter tube could be
blocked. Cleaning it will increase the flowing amount.
