My gas water heater (50 gallon) will spring a leak in the next
two years, if past history is a reliable indicater (Replaced in
'78, '88, and '98, neighbors also get ~ 10 years out of theirs).
It will leak slowly, at first (again, if history repeats).
I want to detect that and replace the thing at the first signs.
Has anyone brewed up a sensor for that purpose? I have two
ideas (but they are not necessarily the best):
1) two pieces of aluminum screening separated by a piece of
thin cardboard. Connections via stainless screws & nuts.
2) Piece of PC board etched to have a bunch of parallel
traces.
The circuit is trivial and I'll use a wall wart - the question
is what's the simplest effective sensor. The tank sits on the
floor, so the sensor can't be directly underneath.
Thanks,
Ed
