Running it to when the low light comes on is way too much water. That first level sensor the tank is about 1/4 full. Doesn't hurt a thing except you don't need near that much to cover the bottom of the tank to prevent piling, etc.
For me, from an complete empty tank, I will run the flusher for 30 seconds on the average volume water flow faucet, longer for weaker flow, shorter for very strong flow (20 seconds). You be the judge. We were staying in a fairground that had 28 psi and the flow rate of an 80 year old man
and I ran the fluser for almost a minute. All of these scenrios are way before you get the low light on, which is overkill. Hope that helps.
PS - If you wanna get anal on finding out exactly how much water a faucet flows, get a bucket and run the faucet at full blast for 10 seconds (don't want or need to waste more water!) Measure how much water is in the bucket and then mulitply by 6. That number equates to a GPM or gallon per minute. Average outdoor faucet is anywhere from 4 to 7 GPM. rockin'
