You know when

[Airspeed]

You know when people say "Leave well enough alone." ?
Do they mean that when the "Sludgebusters" truck has finished cleaning your septic tank, and you find that the 2 x 40+Kg lids haven't been replaced precisely, and you decide to realign them before shovelling the earth back on top; that you should not touch them?
Especially after leaving it for a week, so it's full of "stuff" again?
Possible outcomes being turning a 15 minute back-fill into hours of exasperation?
That being because there aren't any hand holds on the lids, and just because you manipulated one nicely into place doesn't mean that the second one won't flip and drop into the 3,000 litre tank.
I suppose they do.

I feel for you Mike, but that’s given me such a laugh.

I’m trying hard not to laugh Mike, honestly EricT

Oh dear, perhaps you should have left it well alone.
