To know for certain, you'd need to measure your water flow from your faucet at the rate it was turned on, but if its a newer faucet, then if you have pretty good water pressure (60 psi), the faucet will only flow at 2.2 gallons per minute. Thus if you had the faucet fully open for seven hours you may have wasted as much as 92 gallons.
