I have an unoccupied home where the toilet flusher started leaking and I had to pay an exorbitant amount of money to the water company.
Is there a water meter with some kind of wireless connection that will send a message when the water consumption goes above some preset number?
I don’t know where you could buy one, or if you could get one with the sort of alarm system you seem to be talking about, but here in the UK water meters with Bluetooth now seem to be standard. I had one installed last week (for free, by the water company). The Bluetooth is so that they can read the meter remotely, from the street, without having to knock on the door.
So anyway, water meters with wireless certainly exist. Whether they would meet your needs is anther matter. I doubt whether you would get very much range out of one. What you really need, surely, is a way to connect it to the internet.
Anyway, if the property is unoccupied, why can’t you just shut off the water?
Our town, and many other use wireless water meters. The range is limited, they have to send a vehicle up and down the streets to read them and they aren’t smart enough to check consumption, they’d have to be able to keep track of the last reading and the time to do that.
They make wireless toilet monitoring systems. These are often used by hotels. A monitor is installed inside the tank, generally attached to the filler tube. The monitor can tell the difference between a normal flush and a short refill caused by a leak letting the float valve dip to the point where it opens. If it detects the latter, it sends a message to a nearby computer which can then be programmed to send a text message to the maintenance folks.
The toilet monitors are wireless and can communicate over the typical distances between a hotel room toilet and the hotel’s main office where the server computer would be located. You would need to leave a computer in your unoccupied home running 24/7 with an internet connection so that it could send you a text or an email if it detects a problem.
I don’t know what these systems cost or how well they work. I don’t have any practical experience with them.
A much cheaper solution would be to turn the toilet’s water valve off until the house becomes occupied again.
You might talk to the water company. Mine came by and investigated a leak due to a steady higher than normal usage. They didn’t find anything on their end, so left a note about it so I could investigate inside the house. Turned out to be a water hose that was left turned on and was dripping.
Does the house have a washing machine? The toilet is nothing compared to what will happen if the washing machine connections start to leak. They make washing machine shutoff valves for that.
