So, drunks use the bathroom and you want to shut off the water? I see
that being a problem.

This is the situation, we live in the Caribbean renting a house. The
non-potable water for the house is a cistern, w/water supplied by the
local government. The house has a pump that pushes water up to a tank on
top of the house when it gets a bit low. This is an automatic process
when "the pump is turned on". So far, no problem.
This house, it turns out, has a public bathroom attached to it. And you
guessed it: this public bathroom uses -our- private water. While I don't
mind sharing.... anyone, it turns out- can leave the water running,
especially if they are a bit inebriated, as there is a bar nearby.
Usually this is not a problem, as I am home a lot and would just shut
the pump off if it's the middle of the night or something.
I'm thinking of an automatic solution to this... To automate this, I
need a device that will monitor how many times the pump turns on. If
it's, say, 2x or 3x every 10 minutes... meaning that the water was most
likely left on... this device would control a relay that will shut the
pump off for an hour. Then try again after that. If the frequency of the
pump turning on is spaced out more than 10 minutes at a time, then close
the relay and let the pump do its thing.
Does any manufacturer make anything like this?
Any helpful suggestions are appreciated.
Ok how about this
Buy a programmable timer from radio shack etc and set it to turn on the power
for 10 minutes every hour.
That will be the most the pump can then run.
You don't need to monitor the status of the pump or anything, just cycle the
The pump will come on durning the 10 minutes when it needs to.
If you are using less water the it won't come on during the 10 minute window.
