I had an idea earlyer for a circuit thats easy to make, which could detect just about every possible leak in a w/c system. I dont know of any product that already exists for this purpose.
Every system I have built has had very minor leaks usually from barbs unscrewing slightly when tubing is put on etc... easy to fix but always makes me continually check the connections untill its been up for a week or two.

It could be done several ways.

At every hose connection (or other place that could leak/high chance of leak) you would have two copper traces. When they get wet, the resistance is low enough to complete a circuit and activate an alarm.

So assuming any leak forma hose joint would run down the tubing, with the right positioning any leak could be detectable.

The circuit would be cheap to make, and could do other functions if a microcontroler is used (like RPM detection from pump or flowmeter).


Im going to think about the design a bit and make a few for my 4 w/c'ed pc's.
Ill probably use a microcontroler, so not something simple for anyone to make for themelves.... butim sure theres a simplecheapway to make it with LEDs or an alarm of some kind.

if anyone in the UK wants one I could make a few extra, Id like input for extra features it could do (I will include RPM monitoring for DDC pumpfor example).
