There are cheaper optical water level sensors in the aquarium trade that might work for you. Check out the Tunze Osmolator as an example. It could easily be connected to a GPIO on the pi.
- geomark 10y agoThat's a very interesting idea. Thanks for the suggestion. It is still invasive since I have to cut the intake pipe and insert a section with the sensor installed in it. But it is more flexible since I can install it in any size pipe. And for my use case of a 1 inch input pipe it can be cheaper than my current solution.

Although, I wonder if scaling (as in hard water scale) is still going to be an issue.
