I had an idea, and needed a little help where the rubber meets the road.
I'm a landlord here in the midwest, and was just hit with a 800 dollar water bill from a vacant property. It seems the toilet was running for, wait for it...1 month straight. Absolutely horrible, no rent was paid that month either. So on to the idea.
I want to hook up a sensor to the main water inlet from the street, after the meter of course, that closes a solenoid if the water is running for greater the 1 hour (Ideally this could be adjustable).
1. It would have to allow for a little slack, in case of small sink leaks. This could happen and annoy any tenant that is there.
2. It would have to be easily reset, hopefully just a turn of a valve or a push of a button.
3. It would have to be as cheap as possible, for obvious reasons.
4. If it could be mechanical, that would be awesome, as sometimes power can be abruptly cut to the property...
I'm thinking an alarm would need to be present.
A volume meter really wouldn't be necessary, really just something that would recognize if there is any flow at all.
A cheap solenoid could be used, even something adapted from a washing machine or something, it would just need to be at least 3/4" to allow for flow.
I found something like this, but is used in the opposite way,
https://www.lfsmarineoutdoor.com/aqualarm-cooling-water-flow-detector-1-in-fpt-10233.html
It sends a signal if the water flow is stopped, basically used for making sure your engine is staying cool. Either way, a completed product will get you a reasonable reward, I was thinking a Sack of 2 row, or something in that range (maybe more if we could market it)...
I would put this on everyone of my properties immediately, and if it works, it would be fun to sell to all the other landlords I know (Then I could complete a full Blichmann conversion to my system!)...

Ok, so really, if the flow monitor sends a signal (the water is running) to the RC circuit for greater then say 1 hour (this you say is adjustable), I want it to close the solenoid.
If it runs for 5 minutes (say dishes are being done) it counts the 5 minutes, then when the water is turned off, starts back at 0. Basically starts up every time it senses water, and resets if the time limit isn't reached. If reached, BOOM, shut. I would like the reset to be easy though, like something a tenant could do if they were watering the lawn, or left the water running inside for some reason...
Thanks man, I'm going to look into both... and will be getting back to you.
**Edit
What would you call the circuit... All I'm finding is something like this...http://www.youtube.com/watch?v=omS-oWrq0pw&feature=related.
It's a time delay, basically you get the signal, the "light" turns on, and after some time, shuts off. I'm looking for something that gets signal, and after some time, turns on... I'm close though..

Or you can fix the toilet. not trying to be a smart ass, but this seems a little overboard for a what is noting more then a broken toilet, $15 float replacement and your done. I was a landlord in Chicago for a few years and made some good investments. The best way to protect my investment was to keep an eye on my property. If you have an empty unit for more then a month, sometimes its just better to shut off the water. This is no different then your home. My two cents.

Another story, I was on vacation and had a tenant "accidentally" leave the tub running while it was plugged. That water ran for 2 days, the tenant and her boyfriend got in a financial fight, and both moved out. This applies to more then just a toilet.
I'm not going to get snarky here, because I don't want to ruin the vibe of this forum. Thanks for the insight and congratulations on your investments in Chicago.

Another story. We had friends that lived in both Canada and had a home here in Florida. They spent months at either location.
One of the outside hoses was left running (for weeks on end). They received a $2000 water bill. They disputed it, but were not able to get it lowered.
This was 15 years ago... I can't imagine how much it would be now as water prices have skyrocketed.

Crush,
What sort of signal does the sensor need to feed the timer with. I'm looking at a few, and am clueless as to what the alarm needs to start counting.
When the alarm isn't receiving an "on" signal from the flow sensor, will it reset? Sorry for the misinformed questions, any input would help...
I was thinking something like this...

As a quick update, I have the flow sensor connected to a 3/4" solenoid. If a given amount of water is used within a given time, the solenoid closes. If the power goes out in the property, the solenoid closes (NC). A simple reset button is included. A bypass is also included for when the power goes out, but you still need water (in my case for the backup sump pump which runs on water pressure.)
I will be trial testing this in 10 of my rentals, fingers crossed...
