I don't know what is typical, but I just replaced the fill valve in 2 toilets. And one of them the stop valve clogged up and it had very sol fill.

So after replacing it I timed the fill of the two units.

About 1.5 minutes. And I think that they where 3.5 gal toilets. That figures out to 2 gpm.

Or 120 gal/hr, 2880 gal/day, and 86,400 gal/month.

This is absolutely true. Many people have had the same problem. Suddenly they have a bill from the city for $1,000 and they didn't realize the toilet was the culprit.

i certainly did not believe it when they told me i owed $500 for my toilet running last month. i appreciate it though because i was gonna tell them to kiss my ass but now i guess its my fault and will have to pay it. thanks again

Try whining......The utility must have an office of consumer affairs......a back room someplace.......maybe they'll offer to split the payments over several months.......

I know our (expensive) SEWER service is directly computed per water usage........after an un-noticed water leak 'outside'.....the utility adjusted the sewer portion to reflect a "normal" months usage......

Same way if you fill a swimming pool.......
