No overflow with Nova-Flo!
The new sensor of bath overflow – Nova-Flo can save a lot of money and nerves at forgetful fans to take a bath. This completely mechanical device (there are no electrical connections or batteries needed) is installed under taps (see picture) and when the bath water reaches the existing overflow height, Nova-Flo activates and the taps suddenly stop gushing water. No more flood 
This Nova-Flo system is fantastic. I have one installed and I don’t have to worry any more about my bath flooding. It happened before when my daughter left the taps running. The insurance didn’t cover the damage caused to the living room. A great investment. I think it is better than insurance as you won’t have to go through the time consuming issues I did before fitting one.
