You currently pay for the same amount of water multiple times. The meter in your pipes measures total water flow through the pipe. That’s an issue because every time water sloshes back and forth past the meter (even though it’s the same amount of water) you are being charged as if it’s new water.
The ExactWater install controls the excess water and makes sure you are only getting charged for what you use. On average, you will immediately save 30-45% on your water bill.
