Well i hoping the filter on the out going side of my pump will catch all
that or most of it....connecting down pipes to the tank would have the same
issues i think.....

Actually it is quite low about 25mm from the bottom......

Well panel wiring is part of my job so if i cant get that right im in
trouble ;-)

You might get something from R.S..    My drain floatswitch has stuck off a
couple of times and thats why im thinking of using two of the sensor inputs
on of my boards as a backup...

Frank,

Thanks for sharing in another excellent post ? it's given me some new
enthusiasm to revisit water recycling at my house :-)
I need to investigate further, but even if I can't intercept a flowing
pipe, most of my roof water passes to a hollow soakaway so I may be
able to pump it from there. My only concern with this option was what
Lee raised ? the possibility/inevitability of sand & silt accumulating
in the main tank. Presumably the outlet to your pump isn't at the very
bottom of the tank so you could tolerate some build-up before having
to wash/dig(?) it out.

I'm particularly impressed (as ever) with your neat panel wiring and
the level probe. Is there a simpler way to detect level without using
ICs? I've been looking for float switches but none of the cheap ones
I've found are suitable for operating fully submerged. For now I just
need to light a panel lamp on low level?

Cheers,

Tim.
