That sounds easy, but we are talking 1500 or 1600 gallons of water. I
would need to fill a gallon bucket 1500 times and dump it down the
drain. And, no one else could use water while I was doing it.
Somebody must know how these things work. ...Pat


Watch for a half revolution and you only have to fill 800 times.

Is this a curiosity thing or do you need to monitor water use? You can buy
a meter for a couple hundred bucks and be accurate if it is something the
association can use for something.
